Im an engine kinda guy, when it comes to audio, im clueless...

i went to the mall and took off my face plate...i came back out, put my face plate back on, and nothing happened...no power, wouldn't even eject the cd...what the hell is goin on?! a fuse? i checked the one on the head unit...it was fine...my taillight fuse blew later that night, and my dome light/door ajar ring has been blown for a few months (too lazy to repair that one) do i just need to rewire my entire car? what could be causing all this other shit to blow? thanks
