I realize this should go in the Audio forum but I need a quick reply and it takes them forever to reply in that section. I'm still trying to hook my subwoofer/amp to the stock headunit. I can't even get the stock HU out I removed the ashtray and unscrewed the bolt inside but I can't seem to get the damn thing to budge help? Does the stock HU even have RCA plugs or do I need a different adapter? Whats this other **** about battery terminal do I have to have that in order to power the amp? Right now I have the 1400watt amp wiring kit + RCAs do I need anything else?
