I have a 2006 Honda civic ex coupe and need to find my amplifier (stock). Problem is my "audio amp" fuse keeps popping. It pops as soon as I put it in without the radio on and no key in the ignition. I had a problem with the car prior...the battery died/low...I lost the key codes in the memory (immobilizer)...the dealership replaced the inner fuse box and reprogramed the keys. But now the speakers do not work. the radio itself work...turn on...accepts and ejects cds...goes to radio stations.
