what are your volume settings?

bass-
treble
subwoofer-
center speaker-
all that stuff

is it all just in the center?
and is ur SVC low med or high?

 

Bass:3
Treble:4
Center:off
Sub:1
Fade: R1
Ba:center

its starting to rattle regardless of the settings

 

Bass -1
Treble 6+
Center +6
Sub +1
Fade 0 (even)
Ba (center)

I don't like to drown out the mids and highs with the bass, I find with my current settings, my digital audio (XM, ipod, CD) sounds better and better the louder I go without distortion...
