i have a 2003 cadillac cts with stock stereo and a line out converter taped into the rear stock sub(which i disconnected). I have 3 12" subs and 2 amps hooked up the system sounds great when its turned up but when it is down low you can hear feed back running through the subs and when you rev the motor up the static gets louder! any ideas how to ditch the feedback without ditching the stock head unit?could it be my ground or a bad converter box?i need help! THANKS for reading!
