so to make a long story short the previous owner of my Z pulled his radio and speakers and apparently just cut wires to get all his audio equipment so in other words ive been trying to get everything to work, ive just put in my radio and after a while it worked but then i hit a bump and the lights to the dash went out and so did my radio, so then after a while of not working it came back on, im thinkin short somewhere but with this car i cant be sure, any ideas?
