Boss 648UA loses programmed radio stations when I start car.
Nearly every auto stereo has a two power wires. One is switched on and off with the ignition so it will shut off automatically when leaving the car and a second that has power all the time. This second power wire is used to keep time on the clock and to maintain your chosen station memory presets.
If you have wired both power wires to the switched power source, the clock and station memories will be reset each time the car is shut off. You will need to identify the wire that the radio that needs to have powered constantly and connect it to an "always on" 12 volt source (such as the (+) post of the battery).
Additionally, a car battery that is failing can cause the same problem with station memories. Look for indicators such as hard starting or interior lights that dim significantly or go out nearly completely when cranking the engine. This is a visual indicator of an excessive amount of current the battery is trying to supply - often due to a low voltage on the battery. This can be a result of a poor connection at the battery itself, a cable between the battery, starter, fuse box, etc. or a dead cell in the battery. Have the battery checked and replace if needed.
Once your radio power wiring, battery & cable connections and battery health have been verified or corrected - the problem should go away.
