So there was recently a amplifier and a OLD 97 sony head unit and equilizer in my 95 gsx i ripped it out put a new head unit in there, problem i have is i had to cut the factory speaker wiring harness because of the retards before, long story short, connected ground, illumination, power and 12volt switch. i go to power it up it works then i connect a pair of speaker wires the head unit will turn off then back on, continuously also if i try to play a cd i've put in it will continuously shut off and on also..worked fine when i purchased it. tested it right in front of me, for 10 minutes.
