MULTI-MODE CONFIGURATION (4 channel full-range w/derived subwoofer)
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” (BE11 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 channels and get this performance! The amp is run full-
range in 4 channel mode with a passive crossover network across the two rear channels thus
creating amono-bass signal to drive the subwoofer.

CAUTION:
- Be ewe that the combined impedance of your
speaker system as seen from the amplifier terminals is
at least 2 ohms. An impedarea of less than 2 ohms will
cause the amp to shut down.
