System Flexibility; Amplifier Bridging - Rockford Fosgate POWER 1000 MOSFET Owner's Manual

SYSTEM FLEXIBILITY

Four bridgeable channels in the Power 1000 MOSFET provide
unmatched system flexibility with simple wiring changes. Some
of the possibilities are:
Biamplified Stereo - A pair of channels drives mid- and high-
frequency speakers; another pair drives the woofers, The
external crossover (XV-l) is set to separate the input
frequencies into high and low frequencies for each speaker
system.
Biamplified Stereo with Bridged Mono Woofer - Otherwise
similar to the Biamplified Stereo system above, this arrange-
ment bridges the two low channels into a single woofer.
Bridged Stereo - Each pair of channels on the Left and Right
sides is bridged into a full-range speaker system.
Bridged Mono Biamplified - This configuration produces full
power into one mono channel. The front channel pair is
bridged into a mid-tweeter speaker system and the rear
channel pair is bridged into a woofer. The external crossover
(XV-l) is set to separate woofer and midrange frequencies.
Dual Stereo - The power amp acts as two separate stereo
amplifiers, one channel pair for rear full range speakers, one
for front full range speakers. If only one set of speakers can
handle bass frequencies, an external high crossover (XV-l)
can be set to cut off the front speakers' low frequency drive.
Stereo Woofer Amp - Similar to Bridged Stereo except that the
inputs are driven by an external crossover (XV-l) with the high
frequency drive going to a different amp.
All of these system configurations are obtained with simple
wiring variations; there are no special "black boxes" to buy and
the system may be modified at any time.

AMPLIFIER BRIDGING

Operating an amplifier in the "bridged" or "strapped mono"
mode means driving one speaker or speaker system with two
amplifier channels. Each channel will put out full power into its
half of the speaker load, so the system can drive the speaker with
double the power that a single amplifier channel would be
capable of.
