I have an 2004.5 Z with Bose stereo. Like many Z owners, sub started cutting in and out. I connected a brand new Bose amp (no funds for stereo upgrade) and now, NO SOUND coming from sub. Originally, I thought it might be speaker, but is not the case. I connected both my speaker and amp to another Z owners car and it works fine. Anyone have a clue as to what is wrong? It's bad enough that Bose sound sucks, its even WORSE with no bass. HELP!

 

bad connection? see if your power wire, ground and rca's are even working
