Been trying to find someone to fix my sunfire hrs12's. The places I find aren't taking new orders now, they're  too back loged or aren't around any more. Would a smaller plate amp work, didn't really need all the power these put out for my 15x13 room.


I am sure it is not worth repairing, given what is available today.  Try this link at Parts Express.   It's the same size amp that is in the Sunfire.   There are smaller power amps available too, for a little less money.  500W is $140 less.  The other factor is there are better subwoofers out there, although that would be more money.
