Speaker Wiring 2-Channel Amplifier MR800 Tri-mode operation allows you to connect this amplifier to a pair of main speakers plus a subwoofer on one pair of output channels. The main speakers will operate in STEREO while the subwoofer simultaneously operates in MONO. To set up the amplifier to run in this mode, put the crossover switch in the FULL position. Insert high pass filter capacitors and a low pass filter inductor into the wiring as shown below.
