Before you start CAUTION Many new and factory radios require a reset code when disconnected from battery power. This is an anti-theft feature. Before unplugging power, you must determine if your radio/source unit requires a reset code. Check the operation manual for your vehicle or contact the dealer. Congratulations on your choice of a MBQuart amplifier. This “Quick Start Installation” guide is meant to help you “hook up” and play music.
