|cbates670||I have had to replace the alternator and voltage regulator, but that was before the installing of the stereo. I went back with all OEM stuff and have no issues since then with charging. Installed the voltage reducer and now the stereo works just fine. I did test the electrical system to make sure everything running right and all looks good.|

How is your battery and charging system?
I have a dual battery system and parasitic drain from my radio. Need to put it to backup to start car if I switch to early car dies but radio still works

FWIW - I've installed at least 6-7 different stereos in my Jeep over the years and never had a problem with power to any of them. I always run the red power to radio terminal on the fuse block (only gets power with key in the run/start or ACC position). The yellow memory wire (if equipped with such) I connect to the clock terminal on the fuse block (your 73 fuse block may not have a clock terminal, but any circuit that gets constant power like the brake lights should work the same). The black ground wire I usually run directly to the battery (-) post although with the metal dash, the stereo usually works even without a ground wire connected at all.
Perhaps you are on to something with overcharge voltage coming off the battery (+) post (this would indicate a problem with the alternator/voltage regulator), but it seems unlikely because you'd probably be having problems with additional circuits in that case. I assume you're using some type of in-line fuse on your power feed to the stereo? Can you return/exchange the stereo?

|cbates670||I think I have figured it out, I bought a voltage step down to 12 volts. I am thinking that since the Jeep jumps to 14 volts while running it is making the stereo protection system come in. It will be delivered Monday so I will update then.|

I have a 73 CJ5, well it had an old cassette player in it and sounded like crap. I went down and bought a new dual cd/bluetooth stereo, 2 dual 6x9's and two box's to fit the speakers into. So I wired it into the wiring that was there and is played great and sounded better. Its dual so not gonna be amazing lol, well I was going to go to town and started the Jeep and the stereo shuts off, killed the Jeep and stereo turns on again.
Well I figured that there might be some issues with the old wiring, so I traced it and remove all of it. Ran new speaker wire, ran new power and ground wires, one straight to the battery for + and one to the ground block on the fire wall. I wired red and yellow together to + and black to the new ground. Well with the key to the on position stereo plays just fine, but start the Jeep and after a few seconds stereo shut off, kill Jeep and stereo comes back on.
Has anyone else had this issue? Any help would be great.
