i was wondering if anyone has any suggestions of ideas on this.
I was given a sunfire true equalizer sub that was damaged in a surge.
When i turn it on it just emits a low constant buzz.
i suspect the amp is damaged and was thinking about taking it to a local amp guy who might be able to repair it.

Anyone have any thoughts or suggestions what it could be?
I am handy with a solder gun if I have been told what to do. I do not know how to troubleshoot electronics on a component level though.

thanks in advance
