Hello guys, I have a problem with my JL Audio 500/1 amp. The subwoofer sometimes plays and sometimes it doesnt. I looked into it and when i switch aux ports, it works at the 2nd one but with alot of extra noise, and a bit of distortion (Yes, i tried changing out the aux cable, still the same problem). The first one works, but only sometimes. I just opened it up, but i have no idea where to go from here lol. Here are some pics:
And the ports:
Any help would be much appreciated, thanks!
