SYSTEM CONFIGURATIONS
MULTI-MODE CONFIGURATION
Somewhat new to the car audio world is the "multi-mode" configuration which permits three
speakers to operate from a 2 channel amplifier. The benefit is a "quasi-satellite/subwoofer" system
that can be constructed using passive components (i.e., capacitors and inductors) but we highly
recommend the optional "Blaupunkt Bass Bridge" (BB-1) to ensure easy and correct installation as
well as reliability.
Overall, this installation is simple, offers good bass response, and can be done using only one
amplifier as shown below. The amplifier must be capable of this multi-mode operation - you cannot
simply hook up three speakers to any 2 channel amplifier and get this performance! The amp must
be capable of sourcing and sinking large currents in order to do this.
