so i think the rca inputs on my amp have fried, i unhooked my amp last week to pull my box out and paint it and when i got back to wiring it back up as soon as it sees power my subwoofers just start thumping. i have a cresendo bc2k and 2 skar vvx12s, i have replaced the rcas twice since this still does it, i have changed the grounds 3 times, idk what else to test, the left rca input look a little messed up on the amp today i noticed. when i looking into it the black piece that separates the ground and the positive on the amp was not there so i pull that face of my amp off and saw that it had somehow been pushed back so i pushed it back into the input where it belongs, didnt help anything, anyone have any tips/suggestions ? thanks
