How to Install a Car Amplifier: A Basic Guide

What can be more relaxing than enjoying your favorite music while driving on the highway? A quality amplifier can make all the difference. This piece of equipment will breathe life into your music while reducing disturbances.

Amplifiers are not just for those who want the whole world to hear their bass. These devices can replace factory amplifiers, power a full speaker system, and offer a high-quality sound.  

The best part is, you don’t have to take your car to a repair shop to get an amplified installed. Below, we’ll show you how to install a car amplifier by yourself. It’s easier than you think.

Get the Right Tools

First things first, make sure you have all the right tools for car amp installation.

In addition to an amplifier, you’ll need a socket set, a utility knife, an electric drill, and wire strippers. The following tools and accessories are just as important:

  • Pliers
  • Electrical tape
  • Power and ground wires
  • In-line fuse
  • Speaker wires and RCA cables
  • Connector plugs
  • Power supplying cable

Some amplifiers include wiring kits, which can save you a lot of time and money.

If yours doesn’t come with a kit, you can purchase most types of wires and fuses separately. Make a list and head over to the nearest tools store to get what you need.

How to Install a Car Amplifier: Step-By-Step Instructions

Once you have everything you need to install the amplifier, check the manufacturer’s instructions.

Generally, this device should be placed at least three feet away from the stereo. If your car has a subwoofer, see this guide on how to install an amp for subs.

The first step to car amp installation is to open the hood and locate the vehicle’s battery so you can disconnect the negative terminal. Avoid touching the negative lead as it may lead to electric shock.

Next, decide where you want to mount the amplifier and mark those spots. Make sure there are no pipes or wires on the other side. Drill holes where the amplifier will be installed and then use screws to attach it.

Now it’s time to install the ground and power wires. These should be thick enough to accommodate the energy required by your amp.

Try to find a hole in the car’s firewall. Keep the battery’s location in mind and look for a whole on the same side as the battery. If you don’t find one, you can drill a new hole and run the power cord through it.

Consider fitting a rubber grommet into the hole to protect the wire. Install an inline fuse close to the battery and attach the power cable. Next, install the ground wires and remote wires.

Make sure the wires are in place and run the RCA cable along the side of your car. Connect them to the preamp in-dash receiver output.

Wire the speakers and subwoofers, run the cable from the switch back to the amplifier, and turn the car’s engine on to test the amp. Remember to reconnect the negative battery terminal before turning the engine on.
