I have a 2002 Spec-v with the factory subwoofer and amplifier in the trunk. I have a 12 inch Boston with an alpine amp from my old car that I would like to put in my new car. Is there anyway to use the original wiring from the factory sub and amp and just run it to the amp and sub that I just have laying around? Or do I have to run whole new wiring such as, RCA cables, power cable, remote wire, and all new speaker wires???
