    Hello,
    In all likelihood the bass amplifier will have to be repaired or replaced. Do you live in the U.S.?

    Wow, wish I would have looked here before I purchased a PSW111 from the flea market here. Seems to be a recurring problem with the amps on these subs.

    There is a video on YT by a Russian tech. It is not narrated due to language barriers but it is the same heartbeat problem. It is a capacitor issue.
