ICE How to wire an Amp

Once thats sorted firstly you need to locate a place in the engine bay whereby you can run the power wire through the bulkhead easily but shortly. Avoid running the power cable too near to other power sources (especially the coil if can be avoided) as this can cause noise on the amp. If possible, try to use a rubber grommet that already exists and has non mechanical parts running through. Theres usually locations at the top corner of the bulkhead near the battery. If there is no suitable locations, you need to think about making a new one with the drill... When doing this, make sure theres nothing behind it in the bulkhead that can be damaged when drilling the hole through, and that its easy to run the wire through and get to from the inside... (if you do drill, also make sure to file any rough edges off the hole and use the rubber grommet for the hole. Otherwise you run the risk of shorting the power wire to the car body)

Once you've located a suitable hole or made one, you will need to start running the wire through. The best way that worked for me is to feed about a foot through the hole from the engine bay, then go into the car and pull the wire through routing it around various under dash components. You should just be able to poke the wire through as its quite rigid from its thickness. When you've got a clear place for the wire, just pull the rest of the remaining slack wire through. MAKE SURE YOU LEAVE ENOUGH WIRE TO CONNECT TO THE BATTERY AND ROUTE THE WIRE ALONG THE BODY!!!

Now you've run the power wire through from the battery. Its still not connected yet, but that can be done last. Now you need to run the wire from the front of the car to the rear. Try and keep it as straight as possible and away from moving parts - such as seat rails etc. You dont want to cut your power wire when you move things!! IF you prepared correctly, this shouldnt take long at all.
