my step dad did check for current running all the way through, amp is powered, and grounded. remote from stereo is working, amp remote lights up, i put it on half for now. im just trying to see any movement from the sub. doesn't matter where the gain is im getting nothing? grrrr this is annoying. also i feel like i have had the sub to long to do anything even if its broke. its been sat in my room for 7 month whilst i am getting the other peices of my system. im going to have another look. please post ideas thanks
