I recently purchased a used car already wired for an amplifier, however, when I looked at the wiring i found that the installer ran 8 gauge wire and then crimped it to a 12 gauge wire (with fuse) that connected to the battery is this bad? should i change it to 8 gauge? Or does it not matter?
As long as the middle of the wire is not grounding at all. You will be fine. You can run any size gauge wire as long as it connects at each end real good and gets a good connection. The best way instead of crimping anything at all is to get a 100amp fuse where one wire end goes into a slot on each side and a screw holds it tightly. You can run the eight gauge to one side and run the twelve out of the other and thats the best way and safest way to do it so you have no crimped hack jobs on it. -Shawn
you okorder /... you can pull 20 amps 6.6 feet but you can not pull 25 amps any distance so if your amplifier has two 15 amp fuses in it, you will need to swap out the 12ga section for 8ga.
