XM Channel 11 & 3 poor sound quality

[itsjustmatt23]

I have the touch screen navi with XM and I've been noticing poor sound quality from channels 11 and 3. Channel 11 sounds like I have the system faded to only come out of the right speakers while channel 3 sounds monotone. These are the onlu channels that have poor sound quality. I've called XM and they refeshed my radio but it did not do anything... I'm wondering if my radio needs to be replace. Is anyone else having issues with the sound quality on channels 3 and 11? Thanks for your help.

I'm having sound quality issues from all my XM channels. The sound is great on my ipod and a CD but drops about 50% when I switch to XM. I use XM almost exclusively!

When on XM it sounds like I have 4 speakers and 80 watts instead of 17 speakers and 528 watts....... Anyone else have poor XM sound quality?

Mine has always (2 1/2 years) been good considering the severe compression that is present on XM. I see no noticeable differences from channel to channel and no difference in volume when switching between XM and Aux or CD.
