In order for your car amplifier to power on, you will need to connect it to your car battery using a wiring kit. There are different types that are available for you to use with your car amplifier. They come in different gauge size. The higher the gauge, the more thicker copper stands are inside the wire making it more better for larger powerful car amplifiers. To workout what the best wiring kit for your car amp is, its best to refer to the specifications section in the user guide. Although, having a bigger sized wiring kit for a low powered amp will do no harm, it just means you spend that extra money that you didn't really need to.

Here is a car amplifier wiring diagram installation showing you an quick simple overview of how its setup.
Once you have your wiring kit, you are now ready to install your amp into your car as follows.
1) RCA cable. These are the long leads that have double plugs on both ends. You will need to remove the car stereo from the din slot. Look at the back of the car headunit, you will see a bunch of RCA cables. If you connect a subwoofer amplifier, you will need to connect it to the subout. If you connect a 4 channel car amplifier for your front and rear speakers, then you will need connect them to the front and rear outputs. Then all you have to do is connect the other end of the RCA cables into the inputs on the car amp.
2) Connect the remote turn on wire. This is the small wire that is found in between the RCA cables when you split them. This is used to tell the car amp when to turn. When you power on your car stereo it will also send the signal for the car amp to turn on at the same time. This way the car amp is not running all the time to prevent a dead car battery the next day. You connect the remote wire to the blue wire found on the wiring harness on the car stereo, followed by connecting it to the remote turn on socket on the car amp.
3) Power Wire. This is the red chunky cable that is used to transfer the 12 volts from the car battery into the amp. You will need to ensure that the fuse side is the closest to the car battery, in order for it to protect the wiring as best as possible. All you really need to do is run this wire down your cars side panel to the opposite side of your car to were the RCA cables are fitted. This is best to do at first as running both power and rca cables down the same side could cause buzzing or humming interference to be heard through your speakers.
4) Ground wire. This is the same sized wire as the red power one, expect its black in color and really short. This is used to ground your car amplifier. You need to find a grounding location such as a bolt and sand down the area to remove any paint. This will then ensure that you have a proper ground for your car amp, so that it turns on the very first time saving you hassle later on.
5) Speaker wire. This is used to transfer the sound signal created by the external car amplifier into the subwoofer or speaker. Simply unscrew the screws on the terminal for the channel. Insert the speaker wires in, tighten up the screws and connect them to the terminal cup on the sub box. Ensure that you have connected them with the correct polarity. Connecting them the other way around will make the sub play sound backwards resulting in less bass and loudness.
