i bought an audiobahn a500x2q 1200w amp. im installing that with a kicker solo baric L7. my question is what is the best way to run my power wire back through the car. do i have to drill a hole through the firewall somewhere or is there a place i can fit it through. also there is a distributor on top of the battery and it looks like the factory amp is run directly off the battery it looks like an eight gauge wire. is it possible to tap in on the existing wire and and run my audiobahn and the monsoon amp off of that factory power wire. any advice on any of my questions is greatly appreciated, Thank You
