I have a 5.9 ZJ that I just discovered has a bad amp. When I bought it only my front passenger side speaker was working and it was weak. Took the known good amp out of my father's 5.9 and put it in mine. It was alot louder, and all speakers were working great. So now i just have to replace the amp. I saw that a WJ amp might work with a little modification, or just go with a aftermarket amp?

(had to edit, fixed the original issue)

 

i might still have the stock amp in my 96 that was bypassed if you are interested.
