If you’re looking to mount your current car amp or even replace your old system, but don’t know how to do that? Don’t worry in this post we going to cover all of the basics of where to mount and how to wire the amplifier. So let’s get started.

Quick Tips To Install Amplifier

First of all, you need to set up the parking brake. Disconnect the negative (-) terminal from the battery to prevent any electrical shocks. Before doing this that make sure you know how to reactivate your radio.

Step 2 — Mount your amplifier

Choose the place where you want to mount your amplifier. After that Mount that properly in your chosen place.

Step 3 — Install the power wire

The power wire from your amp wiring kit needs to pass through the firewall. Put it through an empty unused rubber grommet in the firewall or cables passing through it and that has enough room for the power wire to fit through too. If you haven’t any existing grommet, then you need to drill a hole through the firewall. Also, you can paint the hole’s edges to protect against rust and put a rubber grommet in the hole to keep the wire from chaffing.

Step 4 — Install the fuse holder

In your amp wiring kit, you may have a fuse holder installed. If so, go to Step 5. If not, then follow this- find a good spot close to your battery terminal to install an inline fuse holder for the power line.

Step 5 — Connect the power wire

After installing the fuse holder connect the power wire to the amplifier.

Plastic wire ties loom provides added protection for your wire against the high heat inside the engine compartment.

Step 6 — Setup The Ground Wiring

Find a bolt to your car’s metal frame to use for ground as near to the amplifier’s location as possible. If you haven’t any ground screw or bolt, drill a hole. Be careful do not drill into any wiring, the gas tank, or a gas or brake line.

Step 7 — Install the remote turn-on wire

The turn-on wire or the remote wire is located behind the stereo. This wire comes with blue and white color. This remote wire will send a signal to your amplifier to turn on whenever the vehicle or the stereo is powered up.
