In summary, you *don't* want to replace the S53AMI in your subwoofer,
even if you could find one. You want to buy a new, different amplifer to
replace what's in your subwoofer, as another poster has suggested. They
are not that expensive, and will put new life into your subwoofer. So
you don't have to throw it away!
