St-4X Sq Speaker Wiring - zapco ST-2X SQ Owner's Manual

If using coaxial speakers, consider using
the HP filters at the lowest setting to keep
deep bass from damaging the speakers as
a crossover and maintain correct.
Similar to bridging a stereo amp to a mono woofer, you can use the 4-Ch amp in a
dual mono mode to create (in this case) a stereo amp with 190 watts RMS/ch.
As with any bridged setup the speakers must be a minimum of 4Ω impedance.
If you are using the active crossovers you should be sure that they are set to the
same frequency
High power stereo using dual mono bridge
hookups requires that the speakers be a
minimun of 4 Ohms impedance each.
