Driving to work this morning i went around a turn and i heard my box slide in the trunk. I opened up the trunk and all looked fine. i get back into car and start it up. i have no sound coming from any of the speakers. Has this happened to anyone? Please help, i have to drive a lot today and i have no tunes...

 

Check your wiring. this happened to me so checked all wires in the back of my headunit this fixed the problem

 

Its Factory Bose, i never touched any of the wiring.

 

you might have shorted something when the box moved
check you fuses
