randomly shut off, i bypassed remote today by touching piece of wire to battery + and remote +, so i figured it was the remote causing me problems. so i tried to relocate my rem. to another + constant 12v, after a few tries with no success, i wanted to bypass the rem. again by touching it to + of battery and now not even that will power it on. im ready to blow this **** up, i love car audio and ive been doing my own systems since i was 15 but im losing faith fast, please help.
