We can't stress this enough as most of us seem to make the mistake of buying the wrong audio system. In this article, we have put together some useful tips that will help you make the wise decision when you want to upgrade your car audio system.

1. What Does Car Audio System Consist Of?

A car audio system is made up of different components which work together as a unit. A simple car audio system includes three main components while a more advanced car audio system will have additional components working with these three. The three most important components of the system are the following:

The Head Unit

While this name is not common, a lot of people know this component as the car radio. The primary function of this component is to provide an audio signal. It consists of digital music, satellite radio, CD players, internet music, and more.

The Amplifier

This component often goes unnoticed since a lot of OEM car audio systems have the head unit and amplifier as a single component as a means to conserve space. The function of the amplifier is to boost the audio signal created by the head unit, so it is powerful enough to cause movements in the speakers.

The Speakers

Audio signals are usually formed as electrical signals in the head unit, boosted by the amplifier, and then converted to mechanical energy to cause vibrations in the speaker. These vibrations display air to produce sound. Car speakers are often full-range speakers. They can also be coaxial, woofers, subwoofers, etc.

2. Facts about Car Audio System

#1 Your car audio system is built around the head unit. It is the core component of the system.

#2 The OEM audio system is not installed as a permanent audio system, and it is easy to replace them with aftermarket parts. All you need to do is ensure that they are of the same size so you can install the new one into the space occupied by the OEM system in your car.

#3 It’s not in all cases that you will have an OEM system with poor sound quality. Some OEM systems which offer some great quality sound include Bose systems, Bowers & Wilkins, Revel systems, Fender, etc.

#4 Amplifiers are often built into the OEM head units for some cars while they are absent in others. This difference is indicated by the names they are called. When the amplifier is built in, it is referred to as a receiver while in a case where it is not, it is called a turner.

#5 Money may not always solve the problem of your sound quality. 50% of how great the quality of the sound you can get often depends on how the speakers are arranged and the location in the car.

#6 There is a range of audio frequency available and using a full range speaker lets you capture frequencies throughout this range. This is why full range speakers are used in lots of OEM speakers.
The only problem which makes them ineffective is that they lose sound strength because they are placed relatively close to one another, and the size of the speakers also causes interference between them.

#7 By installing a subwoofer, you can achieve the perfect car audio system which you desire.

3. Why Should You Upgrade Car Audio System?

Improving your vehicle’s speaker system will not only revolutionize it, but also gives you the best-desired quality sound. Unlike factory speakers, most aftermarket speaker systems offer high-quality material that is strong enough to withstand any warping and can play louder as well as deliver smooth sounds.

How to Choose Your Right Speakers?

Consider the Cost and Model

There are basically three main types of speakers based on their cost. We have the full range speakers, coaxial and the component speakers.
A full range speaker system offers an all-in one parts that are easy to install and the cheapest on the market. Regarding sound, they can produce a different range of sounds. The only limitation is that they aren't customizable like component speakers, which are higher priced than full range speakers.
Unlike full range speakers, the coaxial speaker, on the other hand has two drivers that use the same coil voice. Most OEM system does come with either a full range or coaxial speakers.
So, the point here is to go for what suits you. If you are looking for an advanced set of speakers, then you can as well want to choose from either coaxial or component speakers.

Consider the Sound Quality of the Speaker

Before making a buying decision make sure you find the type of speaker that fits your needs. Ensure you buy a speaker that will fit your favorite music.
An aftermarket speaker offers better quality material. Find out if it has an MRC Cone, Mica Reinforced Cone. Ensure the speaker has a tweeter and much larger voice cone, which will allow the speaker to hold way more power. That means you are going to get higher sound quality and frequency. 

How to Install?

For easy installation, you are going to need the following tools:
● Socket Wrench
● Standard Philips Screwdriver
● TI5 Torx screwdriver
● Panel Tool
● Flush cut pliers
● Until Knife Razor Blade

Step 1:  Disassemble the speaker by removing the panel. Take note of all screw locations.
Step 2: Using the approximate tools, remove each tool
Step 3:  Using the plastic panel and popping tool loosen the panel.
Step 4: Make sure you disconnect the wire harness before finally removing the panel.
Step 5: Next, eliminate the screws holding in the factory installed the speaker.
Step 6: Remove the speaker from the door and disconnect the factory speaker harness from the system.
Step 7: Make sure the kits speaker harness fits the factory connector before connecting the speaker harness,
Step 8: To ensure that the power window doesn't accidentally lock or hook the wires when installed, secure the wire zip ties.
Step 9: After that, plug the speaker into the battery connector.
Step 10: Insert the speaker into the cavity lineup and screw it.
Step 11: Reattached the wire harness and lineup the panel.
Step 12: Push the door in until it clips back into place.
Step 13: Reattach all other panel screws and covers on the door.
Step 14:  Make sure you reconnect the lock switch before you are done.
Step 15:
Repeat this process for other doors you wish to install speakers into.

Common Mistake

One mistake most of us make while installing a speaker in our car is the wiring issue. Make sure you double-check to see if the speakers have the same polarity. The same goes for subwoofers.

 If you have multiple subwoofers, you want to make sure they are also wired in correct polarity. The reason for this is that if you have one speaker while it is going out and the other one is coming in, then the speakers will be working against each other. The best way to check the polarity of those wires is through a polarity checker.

10. Conclusion
