well, a while back my stereo in my car just shut off.. well not just.. i took off kinda hard and got alot of wheel hop and my car was shaking around pretty good.. after that it only worked intermittently, then one day it just stopped working all together.. i thought it was the stereo broken so i bought a new one.. well that doesnt power up either.. i was thinking some wires got crossed, but i redid all that and still nothing.. maybe a fuse.. someone help
