Hi guys it's been awhile since I last posted anything . So here we go I have a 2006 BP5 STI Legacy wagon . Today I started my car and set my music to play via bluetooth which is a aftermarket setup that goes into the McIntosh stereo . And I heard a pop and then the sound went away I've pulled the amp out ( EF-12591 ) and it smells very burnt . I pulled it apart and I can't see any issues I've checked fuses and they're all good . What I'd like to do is replace it totally for an aftermarket amp there seems to be no info on the net on the swap . So has anyone done this before ? Or should I try and find another standard one ? How reliable is the factory amp? I'm a bit lost on what I should do the factory speakers aren't great and I think one or more of the speakers are torn. Any help would be great and very appreciated .
