no sub leads touching anything or loose connections.
brand new rca ran outside the car to trunk away from all power wires. rca's are knu karma kables.
ground for back batt fresh ground down to bare clean metal
sub wires read fine. read 1 ohm at amp and sub enclosure.
headunit at 0 feedback is strong through sub
remote lead doesnt seem to have a break in it and is ran with power cables.
only thing done today was box was slid into place with sub already installed and amp put back in its place. now he has an issue.
