When bridging two D1800M OR D2500M ampliers together, the nal impedance load of the bridged ampliers
should be no lower than 2-ohms. Double power will occur at 2-ohms.
When bridging two D800M OR D1600M ampliers together, the nal impedance load of the bridged ampliers
should be no lower than 4-ohms. Double power will occur at 4-ohms.
Master ampliers positive (+) speaker terminal should be wired to the positive terminal of the subwoofer.
Slave ampliers positive (+) speaker terminal should be wired to negative terminal of the subwoofer.
Now connect a heavy gauge wire (12 Gauge) between the negative (-) terminal of the Master amplier and the
Negative (-) terminal of the Slave amplier.
Please see diagram on previous page for a detailed drawing.
When daisy chaining two ampliers for independent woofers, wire up the the woofers as you would typically wire
them when installing individual systems, even down to 1-ohm. By using the MASTER/SLAVE input conguration
you gain the advantage of having one ampliers’ preamp section control both ampliers, eliminating the need to
gain match and crossover match your system between ampliers.

IMPORTANT NOTE:
CONNECT THE TWO SPEAKER NEGATIVES
TOGETHER WITH A # 12 WIRE STRAP.
