how can you match XM and ML volume levels? anytime i turn on the xm radio i have to turn it up extra 15-20 notches just to match regular volume level from radio.

also
i have ML system...and i cant seem to get a decent level for bass setting. any pointers? i usually have to change settings everyday multiple times

 

i have the same issue.. unfortunately i dont believe there is a source level adjustment in the oem radio...
