I have a 1998 GTP that my brother in law and I are trying to hook a system up to. My brother is a technology and car lover, so this stuff isn't new to him. The problem is we can't find a way to get the amp wire from the battery to the inside of the car . We have everything else hooked up and ready to go, but we have spent countless hours failing at getting the wire into the car itself ? Any suggestions? We also tried the passenger side wiring harness boot under carpet, but we're afraid of what poking a hole or cutting the rubber might do to the car, we're also afraid of clipping a wire and messing something up. PLEASE HELP! Thank you!
