Ok, so about 2 weeks ago there was a buzzing noise coming from my speakers.. i was up early cleaning the car and decided to investigate it. I took out the radio and noticed some wires were not taped so thought that was the problem... however thats when i put it back, now i have no power. It was ejecting cd's up until the other night when i decided to fix it again..... i do not know much about this stuff, please help if possible?
