my system recently started switching off (head unit and amps) and comes back on after a while. once back on I have to reprograme the head unit. this happens all the time. I had the battery checked. all power, ground and remote wires and connections checked. head unit send back to dealer but no fault found. other head unit tested in car with same result. system has been working fine for about 13 months without problems. car: toyota tazz, 2005 model
setup: head unit: rockford ravdvd1, 7" audiovox screen, two targa 4 ch amps, one targa mono block, one farad power cap, power and ground cable size is 4 gauge, 2 fuses at battery and 4 at distribution block

Sounds to me like a problem with the headunit constant power supply, my suggestion is running it directly to the battery with a fuse inline and seeing if that solves the problem those A/V screens are pretty power hungry and the wiring in the harness may not be sufficient.

Humm, sounds like your car's charging system may not be able to keep up with your stereo. Do you have a volt meter in the car so you can see at what voltage the stereo turns off at?
Another thing I would suspect would be a loose connection somewhere, or a weak ground (high resistance).
