I just got my car 2 weeks ago (2000 se with bose) and today when i was at the track i cut the radio off after jammin for 2 hours going down the interstate to the track, then when i leave the track i cut it on and i get the display but no sound.. cds play but there is no sound... then when i got home i discovered faint sound and the back sub humms a little... also it seems to be picking up engine noise, which it has never done... i noticed over the past week that the whole system seemed to be temperamental as far as muddy bass on some songs.. but what is wrong with it.. headunit, relay, amp? i disconnected the amp in the back for a minute and it stopped buzzing and there was no sound... then i checked the connections on the back of the radio and they were fine... checked the fuses and they were fine... i am assuming the relay or the headunit..Help me please!!!
