If by the end of going through these installation guidelines you still have some questions to ask, kindly do not hesitate to contact us or leave a comment below.

Car Audio Installation Budget and Tips

Not all cars are the same. In the same vein, different people like different types of audio output. Some like it heavy while others like it cool.

Trucks and pickups have limited spaces for huge speaker cabinets while buses require a heavy investment due to their spaces.

Small cars and 10 seater vans on the other hand have adequate space to fit the subwoofer cabinets.

To add to these, a majority of the imported cars do come with the original manufacturer audio installed.

But, due to age, most of these audio gadgets have to be replaced. Additionally, the Japanese car stereo needs an expander in order to tune into all radio channels.

Depending on your car, the budget for fitting a simple car audio system may range from as little as $100 and above.

This would entail changing a pair of speakers. However, changing the car stereo and speakers which is the most basic car stereo installation could cost you more.

In addition to these, there are other parameters to look at in regard to pricing. They include speaker size, stereo size, amplifier, equalizer, and cables.

Kindly talk to expert audio installation experts in your locale to get a detailed budget and breakdown of what you need for your car depending on your preferences.

We shall break down these aspects below so that you have a glimpse of everything.

Car Audio Installation Accessories and Gadgets

Just to add on to the above and to help you with the budgeting, below we share with you more on gadgets that you require for this process.

I want to share with you a guideline on how to do a complete audio wiring and set up.

Depending on the wiring setup, you will need some of the above-mentioned car audio gadgets and accessories.

After you have acquired and ascertained that you have all that is required, it is time to start your audio wiring.

But before we do so, let me highlight some of the most important gadgets and accessories that you should give attention to.


First off, make sure you have a working 12 volts car battery. The battery will power all the gadgets.

With a good battery, you are halfway through the journey.

Below are the top-rated 12 volts car battery brands. Kindly click on the links to see the prices.

Car Stereo

After the battery, a good car Stereo is the other important aspect that you should consider.

Any car radio would be appropriate but ultimately, your budget will determine the one you acquire.

In my own opinion, a simple single din stereo would be enough. This is so because the audio output will be amplified.

But due to the features, the pricing may vary. Prices may range from as low as $30 for the single din BOSS Audio Systems 616UAB Multimedia Car Stereo to about $99 for the Pioneer MVH-S310BT Single Din.

There are two major categorizations of car stereos. They are Double Din and Single Din.

Double Din Car Stereo

Just to expound, a double din is a large stereo that measures 7 x 4 inches (180 x 100mm).

Single Din Car Stereo

On the other hand, a single din is the normal slim radio measuring 2-1/8” (50mm) height by 7-1/8” (180mm) 

Double Din car stereos are more expensive as compared to the Single Din ones.

This is so because they have more advanced features like monitors and advanced inbuilt equalizers.

Some of the car stereo brands that come in both variations and you can purchase are:

  • Sony
  • Pioneer
  • JVC
  • Kenwood


Well, the other very important and vital appliance when considering doing some car audio installation is the speaker.

Speakers come in three categorizations; bass (Low) speakers, mid (mid-range) speakers, and high (tweeter) speakers.

All the speakers have their specific functionalities within an audio setup and should be included if possible to get the best audio output.

To get some nice music, you will need a combination of 3 types of speakers IE;

  • Bass or Lows speaker
  • Mid-range or Mid speaker
  • Tweeter or Highs speaker

The bass speaker comes as a sub-woofer, mid-range mainly comes as a 6/9 though there are other dimensions while the highs speaker comes as a tweeter.

Bass speakers are also referred to as woofers or subwoofers and are the most expensive among the three categorizations.

They mainly come in 8 inches, 10 inches, and 12 inches. The most common midrange speakers come in an oval shape and measure 6*9 inches.

Just to add on to these, most 6*9 midrange speakers come as 2 in 1. Meaning, they have two speakers in one.

The midrange speaker itself and a tweeter on the top are housed under one unit. If on a budget, I would advise you to get a pair of these speakers.

A tweeter produces high note sounds. They play a crucial role in balancing mid and low-sound outputs.

We also have the powered subwoofers for those of you that have limited space in your cars.  

Before you think of acquiring a speaker, you should think about impedance matching. What is impedance matching?

Impedance matching. A technique of electric circuit design in which one component provides power to another and the output circuit of the first component has the same impedance as the input circuit of the second component. Maximum power transfer is achieved when the impedances in both circuits are exactly the same.

This has been cited directly from

If you can manage to get an almost exact matching impedance between the amplifier and speakers, then you will achieve the greatest audio output ever.

If impedances are not well-matched, the life span of your appliances is compromised and the audio output is not up to par.

Distortions, overheating, low-quality output, and other audio issues could be a result of a failed impedance matching.

NB; A speaker has a positive and negative polarity and these should be connected accordingly.

Some of the top speaker brands you could have a look at are;


  • Pioneer
  • JBL
  • Sony
  • JVC
  • Boss
  • Kicker
  • Rockford
  • Skar
  • Orion
  • Infinity


  • Pioneer
  • Sony
  • JVC
  • Infinity
  • Rockford
  • Hertz
  • Pyle
  • Orion
  • DS18
  • Massive


  • Pioneer
  • Polk Audio
  • Power Acoustik
  • Kicker

  • Rockville
  • Memphis
  • Hertz
  • Rockford

Car amplifiers are a critical component in the whole process of audio installation.

They help in audio amplification thus a necessary gadget when it comes to quality audio output.

Amplifiers can be categorized into mono and stereo. A mono amplifier has one output and is suitable for low (bass) output.

A stereo on the other hand has two outputs and goes well with mid-range and tweeter speakers.

Remember that an amplifier could have 1, 2, 3, or even 4 channels. Channels are the number of speaker outputs that an amplifier has.

Take note that a stereo amplifier can be bridged to produce or act as a mono amplifier.

Stereo Amplifier

Mono Amplifier

Our audio installers will advise you on this and more. Some of the car amplifier brands that you can have a look at are:

  • Pioneer
  • JVC
  • Sony
  • Kenwood
  • JEC


This will be the nerve center of your audio wiring. This is so because the audio amplifier will ultimately determine the audio output power.

Additionally, the amplifier will also determine the type of speakers, and the equalizer that you acquire for the setup.

Before you acquire an amplifier remember that there are two main classifications of car amplifiers.

  1. Stereo amplifier; This is an amplifier that is mainly built to produce mid and highs {Mid sound & High sound} audio output.
  2. Mono amplifier; On the other hand, this amplifier is built to produce LOW {BASS Sound} audio output.

Remember that amplifiers have channels as well. Channels are the number of available outputs.

In some instances, a stereo amplifier can be bridged to produce a mono audio output.

As an example and depending on your budget, you can get a stereo 4 channel amplifier and a 1 channel mono amplifier. The 4 channels would ideally feed 2 mid-range speakers and 2 tweeters while the mono would feed the subwoofer speaker.

Below are some nice and affordable amplifiers you can try out.

Though most modern car stereos have inbuilt equalizers, an independent external one is a great addition to your car audio setup.

This is because they are specifically built for that function and a majority of them have inbuilt crossovers for great audio separation.

An equalizer is basically used to separate audio outputs. It helps in the realization of quality crisp audio output.

We usually stock two equalizer brands;

  • Boschmann equalizer
  • Pioneer equalizer

NB. The pioneer equalizer is rare and expensive. However, the Boschmann equalizer is quite affordable and performs as well too.


Car audio wiring cables play a very critical role in the audio installation process. They transfer voltage, current and audio signals.

For this reason, a wiring technician must be able to identify and use the correct cables and wires.

To optimally get the correct voltage and current from a battery to the other gadgets, the correct wire gauge should be used.

Furthermore, for a subwoofer and the other speaker categories to work optimally, the correct wires should be in place.

If the incorrect wires and cables are used, the risk of fires and damage to the appliances is very likely.

At Newtrendz Sounds, we have all the necessary cables and wires to perform a brilliant car audio installation process.

Cables and Wiring Kits

This is another very important car wiring accessory that you must put into consideration before you embark on the car audio wiring process.

This is so because there is a risk of fire if the incorrect cables are used for wiring mainly in regards to the battery to gadgets wiring.

On the flip side, excellent performance in regard to audio output can be achieved by using the correct cables.

Furthermore, you can also protect your car battery and other audio gadgets by using the correct cables to do your wiring.

Well, I would classify wiring cables into two categories;

  • Power (electrical) cables. These are used to transfer current and voltage from the battery or source of power to other gadgets.
  • Audio cables. These are used to transfer audio signals.

What matters most is the gauge of the wire. The bigger the gauge, the better the transfer of current.

Well, the good thing is that you can now purchase complete wiring kits that come with all the required cables and connectors.

I would encourage you to go for the complete wiring kits. Not only are they inexpensive, but they also come with all the connectors and other wiring accessories that you may need.
