Rear amp fuse?
 

My brother inasmuch recently jumped my saab and had terminals reversed-- destroyed battery and blew some fuses. I replaced radio fuses behind radio unit, but from right speaker and rear speakers are no longer working. I read in the audio manual that there is a rear amp fuse, but must be taken to dealer to have replaced-- I'd rather do it myself. Any help locating it and advising how to do it would bs appreciated. Any thoughts on why the right dash speaker is not working? Thanks!

I found the fuse and replace it (tricky spot). The rear speakers are working now, but the front right speaker is still out of commission--any advise? thanks!
