radio cuts in and out

this isn't in a jeep, but my girlfriend's radio in her car turns on and off randomly, not corresponding to bumps or movement. i checked the fuse, and it was fine, so i took out the head unit and tested the ground and the two +12 wires with a light bulb, and they have continuous current that doesn't turn on or off. my question is could there be another loose connection somewhere that would cause the radio to shut completely off (including the clock), or are these three wires the only ones that could affect that (besides a broken head unit)? any ideas?

Even though you tested power. Doesn't mean one doesn't have a lose connection. Make sure they are all solid and in strong. There are two 12V wires (one constant, one switched) and a ground. If any one of those are lose, this will happen.

so if those three wires end up being solid and working, then its probably the head unit? im going to try to find a spare head unit laying around and plug it in and see if it works. i just dont want to get one and have it do the same thing.
thanks!

If a new one did the same thing, it can only be something with the wires... But if you really wana test it, you could run a new fused wire to the battery, one to ground and use a relay to trigger the switched wire. Then you'd be sure it's not the wires (unless it's the one your triggering the relay with).

If it has a removable faceplate, check the contacts for corrosion and clean them with some electronic cleaner.
