I reciently had XM installed on my UC and the volume level compared to regular radio and CD is about half. If I switch from FM to XM at same volume It does not have the same base, treble and sound. Anyone else have this problem?

 

Something is definately wrong... Volume should be the same. Mine is.

 

I noticed that as well. I just bump the volume up a couple of notches.

 

I think that is normal for the XM on the HK radio. Mine was that way since the day I bought it. Add an amp and your problem will be solved.

 

any suggestions on a amp? thanks eric

 

I had a xm installed in a pick up truck with the same problem. After a week, I took it back in and told them something was wrong. The audio dealer came out and adjusted the line out option, problem solved. It's worth a try.

 

It's adjustable - read the manual that came with it.
