I have a SPLX subwoofer, and everything was working perfectly until the fuse on the amp wire blew. I replaced the fuse and everything was working okay until the subwoofer stopped working. It only works when I press the middle of the speaker itself, then the bass comes through. I have gone through every possibility, the wiring is fine so im thinking maybe the speaker is now broken?
sounds like a shot VC, but if you have a DMM, test the DCR of the speaker across the coil leads and see what it reads.. that should reveal a damaged coil. If you have an analog VOM, clamp the leads to the terminals, and push the cone in and out, and see if the needle swings a lot for the DCR..
