Actually.. I am also seeing this problem on a brand new 2001 PT Cruiser install. These are the steps I have to do to reproduce it.

1. Turn my key 2 clicks to power everything but not start the car.
2. Turn on empeg and play music.
3. Start car.
4. Empeg shuts off for a second but when it comes back on it still plays music but blinks the battery icon for about 5 seconds.

Is this a problem? Is this normal?

Thanks,
