ok my battery died..and then i started my car and my bose system wont play music..it read its and actsl ike it plays w/ but no music comes outl..whats wrong??

Are you sure you haven't got it muted, or the volume turned all the way down? :)

no im sure i pressed everything and it wont play anything

I would check the fuses. See if the amp is getting power. Check for a fuse on the amp. If that doesn't work, it's time for a visit to the dealer.

i took it to the dealer, adn they fixed it..my volume control sensoer broke..so they replaced it

Wow, how did your battery die?
