okay heres teh story...

i was driving and i have a bunch of tools in my trunk and i turned a corner sharply and u can hear them roll around in the back and then my stereo just stopped working and just turned off, and i can't turn it back on... i also have some wires in my trunk just lying there for subs and amps but yea... idunno if that would have to do anything with it but yea it doesnt turn back on or anything. does anyone know what the problem would be?
