What about the remote wire

Best way to hook up amp to factory radio

Now attach a line of speaker wire to each splice and secure with electrical tape. If the amp doesn't seem to be working properly, disconnect your battery again and go back and double-check all of your wiring for possible damaged wire, grounded wire or loose connections.

You can use the remote fuse in the trunk fuse box. If you have never installed or heard a system run on a stock radio, it is vastly different than one run on an aftermarket. Disconnect your car battery's negative terminal for safety purposes. Run the red power wire from your amp installation kit from the positive terminal on your battery through your car's cabin to the location of the amp. If you don't already have one, purchase a car amplifier with speaker-level inputs and also purchase an amp installation kit.

Run this wire back to your amp and hook it into the speaker-level inputs. Now that your amp is tapped into your car's factory audio system, run speaker wires from the amp's speaker outputs to the speaker s or sub-woofer s you want the amp to power. Connect the red power wire and ground wire you prepped earlier to the proper inputs on your amp. You can usually find one on the sidewall behind the carpeting.

Run this wire back toNow that your amp is tapped

Every amp has pre-drilled mounting screw holes located on each of the four corners of the amp for easier mounting. And since the battery is in the trunk the power and ground should be no problem for the amp. Anyways I was hoping to add a couple of subwoofers and an amp to the trunk but I don't want to change the factory head unit.

Its a million times easier to install up there because all the wires are right there as opposed to anywhere else in the car. Warning Never let your amp rest freely in your car without being mounted, because it can shift while you're driving and damage the wires or even pose a fire hazard.

The installation is quick and easy and won't require removing your factory head unit. Hide all of the cables and wires behind carpeting, panels or trim for a cleaner and more professional look. Other cases, after the amp is fine. This tutorial will focus on how to add an amp by using speaker-level inputs to tap into your car's existing wiring.
