I would like to install a descent size 750 watt Punch amp and a single 12" H2 Punch sub in a ported box. Has anyone attempted this with the factory system. If so where to I get the remote signal and input audio for the amp. Do you recommend running like a 4 gauge power wire from battery to amp? If so whats the easiest access through firewall without disturbing existing wiring.
