Ways to Get Better Car Audio Quality

You Listen to the best Music when your are travelling in your Car, The Best Audio Quality is very Important during your drive, There are a Certain ways to get the best quality of the Audio in your Car Speaker by tweaking your Car Audio System as below,

Getting a Head unit, Installing the Premium Speakers, Subwoofer is important though there are other factors which will decrease your External Interface and improve the Audio Quality,

  • Replacing your Factory Speakers
  • Upgrading your Head Unit
  • Adding Amplifiers, Signal Processor, Equalizer
  • Using High Resolution Audio Files
  • Using of the Sound Deadening Materials
  • Bypass your music player’s built-in digital-to-analog converter. 
  • Add a signal processor or an equalizer. 
  • Set your amp gains properly.

Replacing your Factory Speakers

The Problem – The Factory Speakers might have some Issue so troubleshooting is a must.

The Solution – Should Install some Aftermarket Feature which works with your Head Unit.

Replace your Factory Speaker with the Aftermarket Quality Unit which will go well with your Head Unit, Do a Plugin Play type of the Job where you replace the Speaker with the speakers that conform the dimensions and basic type of the factory speakers. Replace coaxial speakers with component speakers, or even add a subwoofer, but that type of upgrade is both more complicated and costly.

Upgrade Your Head Unit and Ditch Your Phone’s Built-in DAC

The Problem – If you’re listening to music through a phone or MP3 player and an auxiliary connection, audio quality takes a hit

The Solution – Find a replacement head unit that has a USB connection

While upgrading your head unit isn’t always the best place to start when you’re specifically looking to get better audio quality, it’s always worth considering.

This is especially true if your head unit is getting a little long in the tooth, or if it doesn’t have preamp outputs and you’re looking at installing an amplifier. If your Head Unit does not have a Quality Built In DAC, adding a New Head Unit does will allow you to offload the heavy lifting of the digital audio conversion from your phone or MP3 player to your car stereo.  Connect your phone or another device to your car stereo via USB cable rather than an ordinary auxiliary input, This will allow the head unit to read the data from the device and convert it into Analog Audio Signals that gets passed to Amplifiers and Speakers.

Adding Amplifiers, Signal Processor, Equalizer

The Problem – Factory car audio systems are oversimplified

The Solution – Adding Components such as new Amplifier as a part of thoughtful upgrade process.

Adding an amplifier, or another component like a signal processor or equalizer is typically going to be more expensive and complicated than dropping in speakers or even upgrading the head unit. Amplifier can transform the Quality of the Car Audio.

If you’re dealing with a factory stereo that didn’t come with an amp, then it’s important to find a unit that comes with speaker level inputs. The best way to Install the Head Unit with the Speaker level Input but an amp that includes speaker level inputs is at least a workable alternative.

Using High Resolution Audio Files

The Problem – Most cars allow too much road noise in

The Solution – Use damping materials and other solutions to minimize road noise

Upgrading your Car Audio System, they total gloss over the fact that cars make for pretty erratic soundstages. The easiest and fastest fix in this category is to slot some damping materials, like Dynamat, into your door panels.

These products are essentially just sheets of sound-deadening materials that help keep out road noise and other sources of external crosstalk, which is why it’s so easy to install them in your door panels. You can install a similar sound-deadening material on the inside of your hood to help cut down on noise from your engine, and the same type of material can be installed under your carpet to further cut down on road noise.

Installing a big subwoofer in your trunk, the same type of damping material can also help there. The basic idea is to line the floor, side walls, and the inside of the trunk lid, only leaving the divider between the vehicle and the trunk uncovered.

Using of the Sound Deadening Materials

The Problem – Most cars allow too much road noise in

The Solution – Use damping materials such as Dynamat

By reducing vibration and road noise, Dynamat, Hushmat, and other sound-deadening products do two things to make your system sound better.

Setting your equalizer for the best sound

The Problem – Most cars allow too much road noise in

The Solution – Using the Equalizer to reduce the Noise Quality.

Proper use of an EQ can take some tweaking and lots of listening, but that’s the fun part. Start with everything set “flat” and tweak one or two things at a time. You’ll start figuring out what’s missing in the sound and what there’s too much of. Before long, with the equalizer’s help, you’ll have it dialed in just right.

Your crossover can really improve the sound of your system

The Problem – Most cars allow too much road noise in

The Solution – Experiment with the Cross over Point.

Many in-dash receivers now include frequency filters that’ll work with your preamp and speaker outputs. If you have a sub, use the high-pass filter to remove the low bass from your car’s full-range speakers.

You’ll get more clean volume out of them, particularly if you’re driving them with the receiver’s built-in power. Or maybe your sub sounds really strong, but the bass sounds like it’s coming from behind you. Experiment with raising or lowering the crossover point on your low-pass filter, and you’ll be able to bring the bass up forward with the rest of the music.

Set your amp gains properly

The Problem – Most cars allow too much road noise in

The Solution – Set your Amplifier Gains

Our Tech Support people field calls every day from customers who can’t understand why their new car audio system sounds so bad. The #1 problem? Most people think the gain control on their new amplifier controls the volume level.

Naturally, they turn it all the way up, which causes bad things to happen. The gain control actually adjusts the amount of input signal coming into the amplifier. When you crank it up too high, you’ll hear some seriously nasty distortion.

Why Did Your Car Speakers Stop Working?

People Listen to their Favorite Track and Enjoy the Music during their Travel. Most people feel joy when they listen to music while driving, while some people can concentrate more on driving while listening to music.

One of the most occurring problems that people face is that the speakers suddenly stop working while playing any audio. It is a very common problem and is very tricky to troubleshoot.

Speakers are the most important part of the sound system and people spend a large amount of money on them. People ask too many and different types of questions when it comes to malfunctioning of speakers. Some have the problem of less base, some complaints about the low volume, some say it creates buzzing sound, etc. But when the speakers stop, it is a real deal

There are Major reasons why your Car Speakers should have stopped working,

  • Blown fuse
  • Damaged signals wire
  • One speaker working and the other is not
  • Car Speakers not placed properly
  • When speaker wires are pulled out
  • Improper connection of wires

Tools Required to Fix Car Speakers

To undergo the inspection process, you may need the following tools to operate:

  • Screwdrivers
  • Fuses
  • Multimeter
  • Screws
  • Drill machine
  • Work lights

Blown Fuse Problem

The Blown Fuse Problem occurs due to the High Voltage or Current, there are several Fuses to protect every accessory of the Speaker, Speakers are one of those places that can be damaged by a large quantity of current.

So, people install fuses in the speaker wire that is coming from the amplifier to save their speakers from getting damaged. In this way, the speakers get a limited amount of power that they require to operate properly. The Easiest way to solve the problem is to Locate the fuse in the speaker wire and check all the fuses if they are blown. Replace those fuses with the new and better ones so that they do not bother you again.

If the fuse is located outside the speaker box, then it will be easy for you to replace them. If the fuse is located inside the speaker box, then you will have to open the screws of the speaker with a screwdriver and take the speaker out to find the fuses. In this way, you can correct this error in the speakers.

Damaged signals wire

Damaged signal wires are the Important problem to detect in the case of speakers because when the speakers stop working, you may not know what the main problem in the system is.

The speaker wires may be doing some problem, the amp is doing some problem, the head unit is doing problem, or the signal wires may have been damaged.

Whenever you put the signal wires through your car, you must pass it from the sides of the inside of your car. You should never pass them from the footrests of your car.

Another important thing for the signal wires is that you must always install the wires properly, which is pushing the wires inside their port properly so that they must not be left loose.

One speaker working and the other is not

To check that the speaker is fine, but the wire is cut, you must go through some steps.

Get a screwdriver and open your speaker. If it is in the box, then open the screws of the speakers and get the speaker out. When your speaker is out, make sure that the speaker is completely disconnected from the amplifier.

When the speakers are placed very close to each other, so close that the magnetic field of one speaker tries to enter the magnetic field of the other speaker, they will not work as they should.

The speakers have a mechanism with the magnetic coil that creates a powerful movement of the diaphragm, which creates bass and loud sound.

But when the magnetic field is not free to process its power and is continuously opposing another field, it will not work with its full strength.

So, the speakers must be placed at least one foot away from each other to give each other their required space to operate.

Car Speakers not placed properly

Get a New Cardboard and Place the Speakers away from each other, This will prevent the Speakers to be near and giving Distortion sounds.

If you have installed your speakers in a sound box and your boxes are coming close to each other again and again, then mount those boxes away from each other. The best thing to do with them is to mount them away wherever you want but away from each other speaker.

When speaker wires are pulled out

Longer wires are beneficial for your sound setup because, with this feature, you can move your sound system easily. Suppose if you decide to place your speakers to another location and you are out of wire, then you must add a new wire or connect another wire with it which is not a healthy option.

Also, when your speaker wire is damaged from somewhere, and you cut the damaged part from that place to attach the remaining part again, but you are short on wire. You can face many difficulties if you do not keep a good length wire.

If your wire is long and it is pulling out because of the stuff in the trunk, then place the wires in such a way that is attached to the inner surface of the backseat and goes through the walls of your car.

Improper connection of wires

If your speakers are fine, your wires are fine, and your amplifier is fine, then you may have a problem with your connection of wires, The wires must have been damaged so the right power supply does not go to the Speaker or Amplifier.

Try to check your speakers by swapping the two input wires of the speakers either from the amplifier or the back of the speakers if you have pin connections in your speaker box. It works most of the time.

Common Car Amp Problems and How to Troubleshoot to Fix Them?

car amplifier check - best car subwoofer

The Complex Car Audio Systems are often difficult to fix by finding the root of the Issue to Troubleshoot the Issue and Fix them. Though the Components of both the Car Audio and Home Audio Systems are same, The Car Audio System is Subjected to High Temperature because of the Car & Auto Parts Working, The Car Audio System goes through the Vibration, Stress and High Temperature due to the Working of the Engine and the Auto Parts.

Types of the Car Amp Problems as below,

  • Amplifier Doesn’t Power on at All
  • Protect Mode Light Turns On
  • Amplifier is getting Hot or Shutting Down
  • Amplifier Volume is turning down
  • Sounds Like the Amplifier Is Clipping
  • No Sound Is Coming from Your Speakers
  • Hear a Lot of Hissing or Other Distortion from the Speakers
  • Subwoofer Sounds Like It’s Farting

Why did your Car Amplifier Stop Working?

The major Car Amplifier Problem occurs with the noise distortion and the Amplifier Shutting down due to the heat of the Engine or Auto Parts. These two are the Common problem which occurs frequently, and this Issue can be Troubleshooted easily with the below Steps and Maintaining the Proper Precautions.

Why does your Amplifier get Hot so fast?

There are several reasons why an Amplifier is getting Hot too fast and Shutting down because of the Heat, The Major Problems are as below,

  • The Speakers are blown out.
  • The power the Amplifier is getting is very poor.
  • The Bass Control Setting is too High
  • Too Low Impedance

Is it Normal for the Amplifier to get too Hot?

Amps get usually as hot or hotter than the outside temperature even being on without playing music. The smaller they are the hotter they may get. And when not turned on, after a cold night and you check them, they are way colder than the outside temperature, This is normal for any Amplifier so this Situation has also be to taken In consideration that do not make your Amplifier too hot, Take necessary Precautions to protect your Amplifier from being too hot.

What is Shorted Speaker(s)

Speakers which are blown or grounded to the chassis of the Vehicle, The Amplifier will still try to power-in the grounded Speaker. Now your Speaker will get too hot and will be Shutdown easily. Because our amplifiers can play into a direct short for longer periods of time than other amplifiers on the market the problem may go unnoticed for some time before the amplifier shuts down completely to protect itself. When it does, it is a warning sign to check the trouble before continuing to use the amplifier.

 

Guidelines to troubleshoot your Amplifier as below,

  • Problem – Amplifier Doesn’t Power on at All

Solution to the Amplifier Problem as below,

Amplifier should have the power both in the remote and power wires. If it is not turning on because of the Power is not supplied properly, It is time to troubleshoot the problem.

If the remote turn-on wire doesn’t have power, your amp won’t turn on. The remote wire acts essentially like your finger flicking a switch, where your finger is battery power, and the switch is a mechanism inside the amplifier.

If there is no power in the remote terminal, You need to check the radio connecting the Corresponding Wire. If your amp is wired incorrectly, and the remote turn-on is connected instead to the power antenna wire on the head unit, you may find that the amp only powers on sometimes. 

Using the Power Cables which are too small for the amplifier will cause the Thermal Shutdown of the Amplifier. 8-Guage Power & Ground Cable is needed for the Amplifier you are using. The Amplifier Power Cable should be 18” Long and should be the same size as the power cable, bolted directly to a solid, thick steel part of the chassis which is scraped clean of any paint or primer for best possible grounding. positive power cable should be attached directly to the vehicle’s battery using a high-quality battery post adapter and must be fused within 18″ of the battery itself. The power Cabling must be Setup Properly for the overall Performance of the Amplifier.

Amplifier should have the good power and the ground, that the remote wire is having the right Voltage when the head unit is turned on. Also make a Check that none of the Fuses are blown that you are not dealing with the busted amplifier.

Problem – Protect Mode Light Turns On

Solution to the Amplifier Problem as below,

The Amplifiers usually go into the Protect Mode to avoid further damage of the Components of the Amplifiers. If your Amplifier goes into Protect Mode of Light On, then you have a Faulty Speakers, Subwoofer Cable Etc. If the Problem is in the Speaker you can perform the Visual Inspection to rectify the Speaker and Subwoofer in the System.

Use Ohmmeter and Rectify the Grounded Speakers, if any speaker wires become loose and contact ground or if the speaker connections themselves are in contact with bare metal.

RCA patch cables that are grounded out or otherwise faulty can also cause the protect light to come on. To check this, you can simply hook up a set of good RCA cables to your head unit and amp. If that causes the light to turn off, replacing the RCA cables will fix the problem.

  • Problem – Amplifier is getting Hot or Shutting Down & Amplifier Volume is turning down

 

Solution to the Amplifier Problem as below,

 

The Speakers are blown out. The power the Amplifier is getting is very poor. The Bass Control Setting is too High, Too Low Impedance. The amplifier then “sees” a low impedance and tries to keep up with it but heats up due to the extra power it’s trying to make. Once it gets too hot, it shuts down for protection.

  • Problem – Sounds Like the Amplifier Is Clipping

Solution to the Amplifier Problem as below,

 

Audio waveform having a Sound distortion is known as Sounds Clippings by the Amplifier. When there is no Enough Power to the Amplifier from the Subwoofer or other Speakers. You Would need to downgrade or Upgrade the Speaker or the Amplifier. So if you feel like your woofer or subwoofer amp is clipping, the first thing you’ll want to do is compare the amp’s power rating with the speaker.

If you find that the amp has plenty of power for the application, then there could be a problem with your speaker wires, the speakers themselves, or the amplifier’s ground.

  • Problem – No Sound Is Coming from Your Speakers

Solution to the Amplifier Problem as below,

 

Is your Amplifier not turning “On”, Make sure your Amplifier is receiving Input from the Head Unit. Simply unplug the RCA cables from each unit and reconnect them with a good set.

Head Unit is turned On, Volume is Turned Up, Cycle through the Multiple Inputs , like the radio tunerCD player, or auxiliary input. After bypassing the installed RCA cables, then you’ll just need to replace them with a good set. If you get sound from one input but not another, the problem is in your head unit, and not your amp.

If you still don’t get any output from your amplifier, then you’ll want to try disconnecting it from the speakers in your vehicle and hooking up a known good speaker that isn’t in your car.

If the amp drives that just fine, then you have a problem with your speakers or wiring. If you still don’t get any sound, then you could have a faulty amplifier, although you’ll want to check that it isn’t in “slave” mode and that you don’t have conflicting filters before you condemn the unit.

  • Problem – Hear a Lot of Hissing or Other Distortion from the Speakers

Solution to the Amplifier Problem as below,

 

You would need to track down the source of the distortion, you need to know the potential cause,

Inspect the Patch cables and Speaker Wires.

If the cables that connect your head unit and amplifier run alongside any power or ground cables at any point, they can pick up interference that you will then hear as distortion.

Rerouting the wires so that they don’t come close to any power or ground cables, and that they cross at a 90-degree angle if necessary.

Using higher quality cables or wires with good shielding can also help.

  • Problem – Subwoofer Sounds Like It’s Farting

Solution to the Amplifier Problem as below,

 

Strange sounds can come from a subwoofer that’s overpowered, underpowered, or simply installed incorrectly, so getting to the bottom of this particular problem can take some work.

Eliminate the Problems with the Speakers, If the enclosure isn’t the right fit for your sub, then the sub typically won’t sound right either. If the speaker isn’t mounted properly, it can allow air to escape while you’re listening to music.

Impedance matching is pretty simple if you have one sub hooked to one amp — it either matches or it doesn’t. If you have multiple subs hooked to a single amp, then you’ll have to do some calculations based on whether they’re hooked up in series or parallel.

Should you find that the impedances match, then you’ll want to check both the power ratings of your sub and your amp and make the necessary corrections if the amp is either under- or over-powered.

In the event you are using a woofer (or a combination of woofers) that results in a load that’s lower than what the amplifier manufacturer recommends, the amp may shut down to protect itself.

Most common is the use of two 4-Ohm woofers wired together in parallel for a 2-Ohm load, then bridging the amplifier to that load – but the amp is designed for 4-Ohms, not 2-Ohms.

The amplifier then “sees” a low impedance and tries to keep up with it but heats up due to the extra power it’s trying to make. Once it gets too hot, it shuts down for protection.

  • Problem – Gain & Bass Boost

Solution to the Amplifier Problem as below,

 


The most obvious thing to check is your Gain and Punch Bass control settings. The gain adjustment (or control) is a level-matching control that adjusts the amplifier to work with the electronic piece(s) used before the amplifier.

Essentially, by dialing-in the gain control you’re telling the amp how much signal you’re putting into it so the amplifier will reproduce the signal accurately.

If you have the gain set too high, the amp will make full power right away, and you’ll have problems with distortion and “clipping”.

If the gain is set too low, the amp will still make full power, but it might not sound as loud as it should, and you’ll think you aren’t getting much volume.

How to install a SubWoofer in a car – Beginners Guide

Wow! Are you going to Install the Subwoofer for your Car? Checkout our Procedures to Install a Subwoofer. A subwoofer is a special kind of speaker. It’s designed to reproduce the low range of frequencies, resulting in cleaner and better sounding bass than a standard speaker. Subwoofers work with the other speakers in a car stereo system to provide a full range of sound frequencies. You can Fix your Subwoofer System in No time.

In this Instruction, We will show you the whole process of installing an subwoofer into a car.

Best Brand of SubwoofersJBL Audio 10, MTX Audio Terminator Series TNE212D, Rockford Fosgate P300-12 300 Watt Amplified Subwoofer, Orion HCCA122 12-inch DVC 2 Oh Subwoofer, Rockford Fosgate P3SD2-8 Dual 2 Ohm Subwoofer, CT Sounds Meso 8-inch Car Subwoofer Dual 4 Ohm, JL Audio 10TW3 – D4, 10-inch Subwoofer.

Common Size of the Subwoofers – 10 Inch, 12 Inch, 15 Inch, 18 Inc

Required Items for the Fixing of the Subwoofer – You’ll need 3/4-inch-thick medium-density fiberboard, PVA glue, screws, clamps, silicone, carpeting, a terminal cup (which is a plastic cup with terminals to connect the speaker wires to the speakers), speaker wire, and the subwoofer. Tools such as tape measure, pencil, screwdriver, jigsaw, drill, and soldering iron. For the power and ground wires, you will need thicker wires depending on how powerful the amplifier is. REALLY powerful amps could need as much as a 0 gauge wire.

When looking at speakers and amplifiers, do not look at the peak power. A speaker or amp can only be run on the peak power for about a minute before it goes bad or overheats. You want to be running your subwoofers on its RMS rating rather than the peak rating.

Choosing a size for a speaker is also important. Smaller speakers like the 8- and 10-inch ones, are very quick to respond and punch better than bigger ones, but are not very loud. Bigger ones like 15+ inch ones, are very loud compared to smaller ones at the same wattage, but have slow response, and make the sound mushier. The bigger ones also handle lower frequencies better too. 12-inch speakers are a good compromise for a basic system.

The Right place to mount the Subwoofer is in the Front Trunk or in the Luggage back area of the Car.  The flat rear surface of the box should sit against the back of your rear seat, leaving the speaker facing outward into the luggage area.

Measure and Fix the Subwoofer as below,

We will start with wiring the power from the battery. It is important to get the power from the battery. You could also easily blow a fuse by using the little ones the fuse box has. Run the majority of the power cable through the hole in the firewall, making sure to leave enough wire to get to the battery.

If you look at all the wires coming out of the back of the head unit, there should be 1 or 2 blue ones. These are called the remote wires.

If your wires are labeled they may be labeled as:
-Remote
-Rem
-Amp
-Amplifier
-Power Antenna
-Pwr. Ant.
-Antenna
or something similar to one of those.

If there are 2 wires, there should be one labeled Amp. If there is just one blue wire, you can use that. If you have a power antenna, you will have to splice into the blue wire for use with the amp too. What you need to do is connect the 16 – 18-gauge wire to the correct blue wire. When the stereo comes on, so will the amp.

The Measurement of the Box should be few Inches outside the diameter of the Speaker where the Box diameter is more over the diameter of the Speaker.

Size the box by cutting the unwanted space of the box.

You would need a Certain Space in the Box to Mount the Screws to fix the Car Subwoofer.

Put the speaker in the box, making sure the flimsy thin gasket thing is on it.
If the box has its own connectors on the outside, make sure they are wired to the speaker inside.

Predrill the Mounting Screws to a Smaller Hole Size using the Jigsaw and Driller.

Cut the Hole to Fix the Speaker Wires on the sides of the diameter of the Speaker on the box.

Fit the terminal cup, using silicone to seal and secure it in place.

Glue the Sides of the Box Front, Back, Bottom and Top to Place the Subwoofer inside the Box.

The Box should be Airtight so seal the box with Silicon

Spread the Carpet over the Box with the help of Glue and Tightly cover the box area with the Glue and the Carper.

Carper must be cur for every segment where the Speaker holes are neatly visible. The Front Section has to be Glued with the Carpet.

Run the Wires of the Speaker through the Holes of the terminals so you solder the Wires with Positive to Positive and Negative to Negative.

Connect the power cable from the battery into the spot on the amp that has one of the following markings (do not connect it to the speaker positive):
B+
Batt.
Pos.
+12v
12v
Pwr
Power

Connect the 16 to 18 gauge wire into the spot that says:
Rem.
Remote
Ant.

Connect the 3 foot, 10 gauge wire to the one marked (do not connect it to the speaker negative):
B-
Neg
-12v
Gnd
Ground

Connect the other end of the ground wire to a nearby bolt that connects to the body of the car.

Connect the speaker wire to the + and – marked for speakers on the amp. 

The final step is to go and connect the power cable to the battery. Make sure a large fuse is in the fuse holder.

Fit the speaker in place and secure it with screws. Place the speaker cover on the speaker, Connect the wires from your sound system. You’re ready to rock with the Nice Music!
