do u own a dmm? check all of your powers, grounds and remote wires for a bad or loose connection, it's gonna take time and u might have to pull up all your wire and hunt for it, but ive had to do it several times. One time a wire had come undone behind the hu and i forgot i had tapped in back there, made sure to solder it that time. And just yesterday i got my replacement HAT C1 tweeter from Scott b/c for some reason i wasnt getting sound from that tweeter, checked all my wiring 3 times, swapped in another tweeter and it worked perfectly, checked the ohm rating on the other one and nothing...open circuit
