Memphis Maxima

For some reason, when I turn the radio up all the way, I hear a little music, not loud at all, from the rear speakers, but nothing out of the front ones. I also hear a frequency noise coming from the speakers. Do you think it's the speaker amps? Any idea on what it is and what I can do? Can I adjust the amps on the speaker? Shoudl I take it to Circuit City or any other radio place and have them look at it? Please reply with any isuggestions.
Thanks.

the factory bose system is ****. but not any ordanary **** it's the hot green **** that comes out of my girlfriends dog. from now on if anyone has a problem with the bose system just get a aftermarket one. not all aftermarket systems consist of a huge sub in the trunk and a **** load of amps. and if your not into loud music you don't have to spend $100 on speakers like alot of us do. in some cases you don't even need to change the factory speakers. i have a cheap 55wx2 amp powering the two front bose speakers, two aftermarket speakers in the back and two tweeters. then i have another amp for the subs. i've had it hooked up like this for a long time now, this amp powers those four speakers and two tweeter surprisingly well. i have the gain turned down all the way because there's more highs and mids than there is bass.
so in reply to your question fu#k bose just change them. the money your going to spend on fixing it you can put it towards an amp and cd deck.
thats just my opinion
