EPS Subwoofer does not turn on

Has anyone had a problem with their enhanced premium sound where the underseat subwoofers do not turn on sometimes? When I start the car, there is a random chance that the subwoofer will work. Sometimes it does, sometimes it does not. If I park the car for 30 minutes and come back, I can restart the car and sometimes the subwoofer will be working again or sometimes not.

I had the dealer look at it and they could not reproduce the problem. They mentioned it might be due to low battery as it will sometimes turn off accessories if it is low... I never get any low battery warning or anything and they say the battery level looks fine.
