This application is used when you want to maintain the stereo effect
while doubling the output power of your amplifiers. The right amplifiers
are connected to the RIGHT output of the 400 BDG Bridging Module and
the left amplifiers are connected to the LEFT output.
In this system, the 400 BDG Bridging Module accepts the stereo inputs and
turns one channel over 180 degrees (inverts the channel), Both channel
outputs of each amplifier are now connected to the speaker with the inverted
channel being used as the negative input. This works because the two chan¬
nels are 180 degrees out-of-phase.
The ORANGE lead from each amplifier is used as the positive lead and the
YELLOW lead is used as the negative lead. The BLACK/YELLOW and
BLACK/ORANGE leads are not used.
A REMINDER: The speakers must never be grounded to the car chassis
or body. To do so will cause severe noise problems and, in the case of bridging,
cancel out the two-phase operation.
