Factory Bose Radio going out?

[liftednali]

I've got a (OBS) Yukon Denali, with the factory Bose 6 disc changer, the radio, CD, cassette tape that i use for my aux adapter all work fine. I have 2 12" subs and this happens a lot when i play my CD's and have my subs running, at a certain point it stops playing the CD and turns over to the radio. Any idea what could be causing this? When I didn't have my subs in I could play my CD's as loud as i wanted with this problem, it seems it only occurs when my subs are installed. Also when i am in my cassette-AUX mode playing music off my phone it doesn't switch over.

Thanks

subs may be making the laser pick up shake or the the button contacts close from the vibration and maybe one of those two reasons may be making the radio a default choice.
Maybe too much bass
