What's up guys, you've probably already heard a similar problem but i did research and still can't find a definitive answer. It's a pioneer avic-d3 head unit, Rocksford fosgate sub, amp and capacitor.
I'll just state that when the sub did work, it bumps.. Or thumps once whenever I turn the car on or off.
One day I hit a pothole and the sub stopped working, sometimes id hit another pothole and it would work until the next bump I would hit. Than for a little while it wouldn't work even when hitting bumps, but would work if I turned hard enough, it would work for the duration of the turn. Now it doesn't even do that, except for maybe a couple days ago it worked for an hour now doesn't. I'm completely clueless, my RCA's are fine. Wires have a secure connection, I don't know. I want to figure it out before I have to take it to a place.
