if your finding voltage drop due to bass peaks to be a problem, id advise getting hold of a split charge relay and givving your amps (and obv subs) thier own battery, its easy to wire, if your interested let me know an il post instructions on wiring a split charging system, and because its run off the double pos+ system of the alternator warning light, you can thump your tunes out for hours without having to wory about starting your motor afterwards. hope thats of some help
