I picked up this sub really cheap to have a go at fixing it but I have no experience with digital amps and am not sure where to start. The former owner said it was intermittent, i.e., it would work one day and not the next.
I've been unable to get it to fail completely, but it cuts out at very low volume. I've eliminated the speaker driver itself and it happens on either line level input, so it's not likely the typical loose solder joint at the mechanical interface of RCA to board.
Would a cold solder joint in the early amp stages be a likely culprit?
