While on the way there, the journey becomes more relaxed if we are listening to some music. This is where a car audio system comes in. Our cars come equipped with a radio receiver and possibly a CD player unit. These stock parts produce good sound but it is often not quite as clear and crisp as we would want. Therefore, many of us turn to aftermarket products and construct our own unique car audio systems. A car audio system consists of many parts. These include the speakers, amplifiers, equalizers, cabling and possibly an extra battery. These parts range in price from affordable ones to wildly expensive units. Read on to find out how to build a budget-friendly audio system for your car.

Determine Your Budget

This is the most important step when you begin the journey of building an affordable audio system for your car. You need to identify how much money you want to spend on it.

Find out what you want and perform some research to find out the lowest prices you can get for each part you want. After that, add up the prices and get an estimated total. This is the budget which you will work with going forward.

The Car Stereo

This is the heart of your car audio system. You may decide to change the stock car stereo in your car and replace it with an aftermarket unit that produces better sound. Also known as head units, car stereos are diverse. Some have just a few features while others have it all. Refer to the features which you decided to search for as you were making your budget.

An aftermarket car stereo is not powerful enough to power your car audio system. Thus, you need a unit that can boost the signal from the car stereo to the speakers. This unit is known as an external amplifier. There are two types of amplifiers. These are the mono channel and the multiple channel amplifiers. A mono channel amplifier can only send signal to one speaker. On the other hand, a multiple channel amplifier can send sound signal to many speakers. There are multiple channel amplifiers which can handle up to 6 speakers. It is advisble to buy a multiple channel amplifier. This is because you can always connect new car audio equipment to it in future. Perform some research so as to find an amplifier unit which can power your front and rear speakers. Remember to check the power rating of your amplifier. You do not want to send more power than your speakers can handle. This can damage them.

There are many sizes of subwoofers. Examples of these are the 8 and the 10 inch subwoofers. Car audio amplifiers normally have some special characteristics which you should know about.
