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

    I would recommend removing the plate amp and shipping it to one of the Sunfire repair centers. There is Flannery Auto in Washington, and someone in Chicago, but I'm not sure of the name. Most repair shops don't have access to Sunfire schematics, Etc. They are pretty hard to come across.
