[QUOTE="Lasherž, post: 8709989, member: 679555"] Grounds are notorious for failing even when they're tight and look secure, especially after 10 years. I'd take that bolt off and resand the surface and the connector, then tighten it back up snug. Maybe also check the car's ground connection off the battery for good measure. If that doesn't fix your issue then get out the multimeter and per 1aespinoza/audiobaun's suggestions, check the resistance at the enclosure terminals. It should be anywhere from 2/3 to 3/4 of the expected impedance (I don't know how your subs are wired). If it's lower you likely have a bad coil or a strand from one terminal has snuck over to the other terminal (either at the amp or at/inside the enclosure). If it's higher you either have a bad coil or a connection is loose inside the box. He also made a good suggestion to refresh the fuse connections, I might redo the battery connection as well and if the copper strands are largely oxidized at the amp connection (+ or ground) cut them off and strip the wire for fresh strands.
