Amplifiers increase the output from your vehicle’s sound system so you can listen to music louder and improve the sound. A car amp can be a difficult installation since you’re working with your vehicle’s electrical system, but you can finish within about 3–4 hours. Start by finding a flat spot inside your vehicle and screwing your amplifier down to...
Disconnect the negative terminal on your vehicle’s battery.
Open the hood of your vehicle and locate the battery near the front of the engine bay. Use a socket wrench to loosen the nut holding the negative terminal to the battery, which is usually black and marked with a negative symbol (-). Set the cable for the negative terminal aside while you’re working so it’s out of the way.
Don’t touch the negative lead to the positive terminal since you could create a spark or shock yourself.
Never work on your vehicle’s electrical system while the battery is still attached.
Mark the amp’s mounting holes on your vehicle’s floor where you want to mount it.
Choose a place that has flat floors, such as your trunk, in the passenger seat footwell, or under the rear seats. Check underneath your vehicle to make sure there aren’t any wires or pipes on the other side of where you want the amp. Hold the amp still as you mark the locations of the mounting holes in the corners with a marker or pencil.
Buy an amp installation kit so you have all of the proper wires.
Look at an automotive store to see what options they have for installation kits. Get a kit that has 8- or 10-gauge wiring so they can carry the full current without overheating and melting. Open the kit and separate all of the components so you can stay organized while you’re working.
Installation kits usually cost around $15–20 USD.
The installation kit will include a red power cable, black ground cable, blue remote wire, RCA cables, in-line fuse, and connectors for all of the wiring.
It does not matter what kind of stereo you use the amplifier with. You can use the stock car stereo or use one that’s after-market.
Find a hole in your vehicle’s firewall on the same side as the battery.
in (1.3 cm) off the ends of every wire you ran.
Grip the wire in the jaws of a wire stripper and close the handles together. Pull the stripper toward the end of the wire to cut off the insulation covering the copper wires. Be sure to strip
inch (1.3 cm) of insulation from each end of the wire. Repeat the process with all of the other wires you’re connecting to your amp.
Be careful not to cut or damage any of the wires, or else you may need to feed new ones through your vehicle.
If you don’t have a wire stripper, carefully slice the insulation off with a utility knife.
Push the power cable into the 12 V input on the amp.
Connect the end of the ground cable to a bare metal bolt.
Lift the carpet or trim near your amp and look for a bolt that has bare metal. Use the end of the ground cable that has a ring or bracket to attach to the bolt. Loosen the bolt with a socket wrench and pull it out. Line up the end of the cable with the hole before feeding the bolt through it. Tighten the bolt completely so the cable has solid contact with the metal.
If there’s anything attached to the bolt, be sure to support its weight when you attach the cable so it doesn’t fall and break.
Don’t attach the ground cable to a painted bolt, or else it will not work properly. If there’s paint on the bolt, clean it off with sandpaper first to expose the bare metal underneath.
Secure the remote wire to the amp turn-on wire plugged into the stereo with a butt connector.
Look for a blue wire with a white stripe that’s already attached to the back of your stereo, which is the turn-on wire. Leave the turn-on wire plugged into the stereo and remove
Reconnect the negative battery terminal to test the amplifier.
Slide the negative terminal back onto the port on the battery and push it down as far as you can. Tighten the nut with a socket wrench to secure the terminal back to the battery so you’re able to use your vehicle again. Turn the key in the ignition to start your vehicle and check if the power light turns on for the amp.
If you don’t see the power light turn on, shut off your vehicle and disconnect the negative terminal before checking all of the power connections.
Turn the gain on the amp down as far as it can go.
Look for a knob or screw that’s labeled “Gain” or “Amp Sensitivity” on the front of your amp. If there’s a knob, turn it counterclockwise by hand to lower the gain. If there’s a screw, turn it counterclockwise with a screwdriver until it doesn’t go any further.
The gain controls how loud the amp will output the audio from your stereo.
