I might be a little late to the thread but OP, I'm pretty sure our bike's run on a 6v electrical system so it'll be rather complicated to run a 12v car amplifier off this. Even the best amps go into protect at 9v.
As far as the car audio talk, right now I'm running 2 12 inch BTL's on a Cactus Sounds K5 (5100 wrms). Let's just say I've had to replace my windshield
