If you have an old head unit that has no RCA jacks and you want to hook up and additional amp in your car audio system. You know it is very complex to install an amplifier in your car and when there are not even RCA jacks available, it becomes a little more complex.

An old head unit is not useless just because of the lack of RCA jacks. You should install an additional amplifier in your car to increase the power for running speakers or subwoofers.

When we move to hook up an amplifier, there are many methods available to perform this task. It all depends upon the type of equipment being installed and the number of methods available to connect.

Before we start, make sure the amplifier can accept speaker or line-level connections. And the other thing to check carefully is that the RMS power of amp is less or very close to the RMS power of speakers. If it is more than speakers, it can damage the speakers.

RMS: Root means square or RMS is the power at which a speaker or an amplifier can work continuously. Not to confuse with peak power, which is the maximum power a speaker or an amplifier can reach but cannot work at this power for a long time.

Where to place amp in the car?

First of all, you must decide a place to hook up your amplifier. There are many places to mount the amplifier in the car like at the back of a seat, behind the seat, between the seats, sidewall, back of a subwoofer box, etc. Don’t mount it close to any loose item that could damage the amp when you drive the car.

If possible you can also place it in the trunk of car. When you place luggage there, it may become difficult for you. Also, try to keep it at a place where it could get cool air to get cool as it will be getting hot while running.

Safety Tip: For safety, disconnect the negative terminal of your battery before you get started.
