gf has a 00 integra gs i have a 99 integra gsr. the problem is that the head unit doesnt work in her car and it works in mine. my stock radio works in her car and mine. she has her car hooked up to a system as well. when i was wiring it up the harness on her car to check if the head unit powered, it did for about 3 secs and wires came loose and never turned on again. i already checked fuses as well. i recognize that my car uses 15a fuse for radio and the head unit worked in my car, and hers uses a 10 and only stock worked in hers. i was wondering if anyone can help me when this problem. the headunit doesn't turn on in her car thats what i meant by not working.
