If you just want to though, just get plenty of 4 gauge and run it from your alternator to battery positive, engine to chassis ground, and battery negative to chassis ground. Then run it to your amp and use some to make your ground for the amp. Put an inline fuse of around 80 amps on the run going from your battery to your amp within 18" of the battery connection. Also, you can add this on top of the existing factory wiring. There is no reason to discard the factory harnesses and connections. As for the starter wire, it does not come into play in this upgrade.</p></blockquote><p></p>
