I have spent most of yesterday checking connections and redoing them. Before that the only thing I did was actually put a crimp on the main remote line running to the amps as to how I had them before just twisted together and taped. before the crimp I rarely got that THUD sound and now it happens every time I take key out of ignition without turning off radio first. Heres what I have kenwood HU running to, clarion EQ, from there to one Rockford P1000-1bd and a P400-4 I guess I'm being lazy and should just undo that crimp but I think that crimp is stronger than just twisting line together, could I be wrong? could I have done the crimp wrong?
