I have had this head unit for awhile now but took it out of my vehicle about half a year ago due to it not wanting to turn on. When i was messing with it to see what was going on I figured out that if i grounded the radio to its metal case it would turn on... Weird right. So i put it back in my vehicle earlier this afternoon and ran the ground to the back of the case where a screw was. Works perfect. Thing is when i turn my amp on it freaks out and stays on. Its just hitting constantly. I know this is probably caused by the way i have the radio grounded.
What I am wanting to know is has anybody ever had this problem or heard of this. It will not turn on through the head unit ground wire, has to be grounded on the head unit case. If so how could i go about fixing this or is the radio pretty much dead.
