not clicking or popping (99% sure, last time i listed to it was 8hrs ago), amps are grounded to a battery (Hc800). But it might be the RCA issue. Ill try and get a vid of what it sounds like to get a better idea. But that will be in about 10hrs.
im just trowing out ideas but hopefully you can get a good 100% diagnosis of what it sounds like or is and can get it fixed
yea, ill clamp the outputs separately of each amp, ill pull the deck out and check the RCA connection, maybe its loose or something. I need to check the wires connecting to the sub, etc. Ill go through a wiring check after i get out of class.
