Hey,

Something I noticed recently: if my radio is off (like off off, not just 0 volume) and regardless if the engine is on or off, there is a slight hiss from the speakers. It's constant and it doesn't really interfere with my music when it's playing, but it irks me a little. Does anybody else have this? Any ideas how to clean the speaker signal out?

Car is an 04 with the Bose audio, no navi. No ipod hook ups or anything like that.

Thanks

That IS strange.. maybe a bose amp problem? I would ask the dealer about that one

check connections to the speakers

perhaps your speaker has worked for a long time.i think there is nothing wrong with your connections ,if it has problems ,your speaker won't work normally.
you have heard some noise in it ,i think it is the time to change your speakers.you could relate this to your home theater.if you change a new speaker,there would so cool for the sound.and a new pair of speaker wouldn't cost you so much,look at this one ,Polk Audio DB651 6.5-Inch Car Speakers (Pair) $35.00 (http://www.dealstudio.com/searchdeals.php?type=id&q=d92460&ru=2780299),it has a high performance,and good music becomes great when you hear it.
