NOTE: This wire must run from Negative to

Bridging
Bridging is a way to combine 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.
2 KS 1200.1 s or K S 2500.1 s in a bridged configuration must not be connected to a load
lower then 2 ohms.
For bridging 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” as above but the
slave amp must be set to “Out of PHASE”
Use the configuration below.
AUTO SENSE
The KS 1200.1 and KS 2500.1 uses a Patent Pending Auto Sense Turn-on circuit that
offers a significant improvement in reliability over previous designs. Instead of relaying on
the music to supply enough signal to turn the amplifier on. Robert Zeff’s new design
detects the IC (chip) used in the vast majority of stock head units and amplifiers.
To use the Auto Sense feature on the simply connect the factory speaker wires to the High
Level Input and watch it work.
MASTER/SLAVE
The
KS 1200.1
and
KS 2500.1
are equipped with a MASTER/SLAVE circuit. This allows you to
control 2 or more amplifiers from one set of controls. All of your gains, crossovers, bass boost,
subsonic filter and remote level will be controlled from a single “master” amplifier. This
eliminates all the tedious gain and crossover matching normally needed when using multiple
amplifiers.
