Car Audio Amps

Let’s talk about how to hook up an amplifier. For those who never installed an amplifier before, sometimes it can be an overwhelming and daunting task. Once you understand the basics of how to do it, it becomes very simple. There are three main parts to hooking up an amplifier. Number one, you need power your amplifier. Number two, you need to give your amplifier an input signal. Number three, you need have an output signal coming from your amplifier to your speakers or to your subwoofer.

First, let’s talk about how to power your amplifier. Here, we have Stinger SPV44 battery. It is very important to disconnect the negative battery terminal when you’re doing an install like this. And, here, we have our four gauge power cable and four gauge ground cable. The first thing we’re going to do is to connect the ground cable to a terminal of the amplifier. Put it into the portion of terminal that says ‘ground’ and screw that down. Once we have this connected from the negative on the amplifier, we’re going to ground the other side of the cable to the chassis of the vehicle. Now that we have our ground cable connected, we’re going to connect power cable. With our stinger battery, we’re going to connect this with our battery clamp. Connect power cable to the positive battery terminal. The power cable goes through the fuse holder and then is connected to the positive terminal end of the amplifier. After this, we’re going to connect the remote turn-on wire. This connects to the wiring harness of your receiver. In this example, we have Kenwood DNX6140, a fantastic GPS, navigation receiver. It is color coded and labeled on the back of the wiring harness. Different manufacturers use different color codes and different ways to label, so you need to be careful and make sure you connect the correct wire. Take the wire and connect to the remote turn-on portion of the terminal on your amplifier.

Once you have the wires connected, it is time to give your amplifier the input source. Here, at the rear of the receiver, we have RCA interconnects, Kicker X-series RCA interconnects. They are connected to the subwoofer out portion on the receiver. Take the other side of the cable and connect them to the amplifier. Now that your RCA interconnects are connected, your amplifier is receiving an audio source and you need to give that source some place to go.

The last part of setting up your amplifier is to connect it to your speakers or your subwoofer. We have here Kicker CVR subwoofer, which is already prewired. Secure the speaker wire in the output terminals. Once your subwoofer is connected the amplifier, our installation is done. The whole procedure is very simple. Remember the three steps of installing an amplifier: 1. Power the amplifier 2. Give the amplifier an input signal 3. Connect your speakers or subwoofer to your amplifier for your outputs.
