Re: THumping coming from my subwoofer after i turn my stereo up
bad amp? sometimes stuff doesn't work right out of the box. you would have to swap in another amp to see if it's the amp or not. but i would try gain at zero and see what happens when you turn it up for sure. double check your rca out on your HU are still working. maybe they broke? don't rule it out until you have checked to know for sure.
