I drive a 99' Pontiac Grand Am and I already bought the stereo system, and installation kit. The previous owner of my car had a sub in the trunk, and it was wired to the battery for more power for some reason. So because it was hooked up that way we haven't been able to get my new stereo system to work properly. It was all connected and put on right but would not turn on. So I need a mechanic to unhook the wire on the battery and put the wiring in the right spots.
How much should I take with me to the mechanic?
