So i have 3 amplifiers( 1 for the 2 12", 1 for front speakers and one for the rear interior speakers). I only have 1 battery and it is a redtop. Recently it seems to have a continual on off when car is not moving more so then anything else. Seems to not happen as often when i am on the accelerator. I thought it was a power loss issue so i turned the gains down. Also thought maybe it was my alternator but i tested with voltmeter and it showed 14.5V. The only other thing that i have done was that i connected a fan to one of the amps ground and 12v remote wire to help keep sub amp cool. Could something this simple be causing the constant on off?
Could this be a bad ground wire ? a bad RCA? or do i need to go with a high output alternator.
