Before you start running the wires for your car amps you will want to make sure that you have all the necessary tools and wiring and equipment to install your car amps. Then you will want to make a plan for how you plan to route your wires making a note of any components or parts that might get in the way. The first wire I like to run is the power wire. This is usually the most difficult since you are usually running the wire from under the hood through the firewall and inside to the car amps. Some cars such s BMW's and Mercedes Benz have the battery's in the trunk, usually making for a fast install of the power wire if you are installing the car amps in the trunk as well.
You will want to make sure you run the power wire and the remote turn on wire on one side of the car and on the other side of the car run the patch cables or RCA cables. This will help prevent any engine noise from entering the system.
Now you will want to run the power wire from the battery through the fire wall making sure you keep the wire away from any moving parts or components. When running the wire through the firewall I first look for a pre drilled hole that simply does not have any wires going through it. If none of these are present you will need to drill a hole. Make sure you know exactly what is one the other side before drilling.
You will want to run all the wires underneath the panels and carpet for safety and it will also give your system a pro installed look, so after the wire is in the car you will want to remove the kick panels and entry plates or scuff guards and run the wire under the carpet and to the place where the car amps are to be installed. A panel remover will come in handy when removing some of the interior panels and will help not to damage any parts.
