I have picked up this sub in great condition, for $40.
Initially, it was dead. Found the fuse blown. After I have replaced it, it turned on(LED turned green), but did not make any sound.
Eventually I have found very high resistance on the speaker, which was changing it's value.
I have found the tinsel wires were causing this issue. At least that what I think at the moment. I still need to replace these wires, to be sure.
Also I started on the amp, which works, but has a buzzing hum.
Unfortunately, my esr meter is broken, so I can't measure capacitors.
I have removed a bunch of that caulking. In some spots it was darker, which most likely it started to be conductive.
My question is, which capacitor could be causing this sound?
Course, there is no schematic for these.
Voltage at the amp is +/-44.9V.
