I just bought a Swank 91 GMC stub Van. Im working on a sound system... but Im venturing into unfamiliar waters with a subwoofer set. heres where im at now. Im installing the stereo standard to 4 speakers 50 watts each... now the sub. so far i have a ( Bought the 105.00 best buy cable kit ) moster red power line through my firewall to my battery 100 amp fuse inline. to a mono amp now, the rca looking jack things go to the stereo right? the woofs just run off the amp speaker outlets. amps grounded. now my question is this remote thing? Whats that do? and also... ive got straight power to the amp how does it turn on n off? do i need a toggle or something? or do those rca jacks hoked to the stereo control it?
