1) is there a way i can switch on and off the subwoofers? like when im parked and i dont want to bump it cuz my battery would die out. would a toggle switch between the amp and head unit (on the remote turn on wire) work? do i need a relay, or fuse, or something? doing it this way, is it safe? 2) i got an alarm installed with power door locks. (i have a 96 civic DX) is there a way i can lock and unlock the doors without using the remote or activating the alarm? maybe install a switch somewhere, some how. i believe i need a relay of some sort. can some one tell me how to do this? thanks in advanced.
