Strapping
Strapping is the same thing as Bridging but refers to using 2 amplifiers This is a way of combining the power of 2 channels into 1.
When you wire the amp bridged you have a higher voltage differential b and -. That means MORE POWER. If you have 2
identical, properly designed mono amplifiers (They can not be a stereo amp that is bridged internally) you can bridge them together
to create 1 channel.
Warning
When bridging any amp or amps, each channel sees half the Ohm load. 4 ohms bridged is the same as 2 Ohms stereo. 1 ohm bridged is equal
to 1/2 ohm stereo. Check the compatibility of you woofers and amplifier before you begin.

s in a bridged configuration must not be connected to a load lower then 2 Ohms.
For strapping to work both amplifiers must be playing exactly the
same signal at exactly the same output level. To make this easier
use the “MASTER” and “SLAVE” but the slave amp must be set
“Out of PHASE” to the Master.
Use the configuration below.
Set to
NORMAL
Set to
SLAVE
WARNING:!
This is not a typo. You must
use both Positives (+) to drive
the woofer. The Negatives (-)
of both amplifiers must be
tied together. Failure to follow
this procedure exactly could
lead to amplifier failure.
