This diagram shows a method for summing only the lows and permitting
the midrange and highs to remain in stereo. In this system, an ORION
200 CRX Active Crossover is used to separate the lows from the highs as
described in figure 5, and the 400 BDG Bridging Module is connected only
to the lows side. In this way, the midrange and high frequencies are applied
to the highs amplifier as stereo. Both channels of the low frequencies are
applied to the Bridging Module. In the 400 BDG Bridging Module, the signals
for one channel are turned over 180 degrees (inverted) with respect to the
other channel. The inverted channel output of the amplifier is now used as
speaker ground and the non-inverted channel output is used as speaker
positive. The BLACK/YELLOW and BLACK/ORANGE leads are NOT used.

This diagram shows two 8-ohm subwoofers connected in parallel. This
reduces the impedance to a total of 4 ohms thus increasing the effective
power output even more.
For installation, connections and adjustments, refer to pages 26 through 35.
