No sound from speakers, '99 e36 323i convertible
The speakers on my 99 323i convertible suddenly quit working three days ago. Factory business radio and HK speakers. The radio still appears to be working fine and the CD player also seems to be working fine. I checked fuses under the hood and also pulled out the radio unit and checked fuse and connections behind unit. I located the amp in the trunk. Is there a fuse for the amp that I'm not finding? Is there something else I should be checking? Or does it appear that my amp is blown? Thanks for all the help!!
