Mono Operation:

Here we show how to use the 2 channel amplifiers as a 1 channel unit by taking advantage of the mono bridging capability of all MB Quart amplifiers. Interconnect cable checklist:

-A MONO signal source is required to bridge channels 1/2, such as would be available from the mono sub bass output of an active crossover, whether standalone, or built into a head unit or equalizer. If you only have 1 set of RCA outputs from your headunit, you can simply connect those to the inputs for ch 1/2 and switch the X-OVER to LP/BP. The amplifier will auto sum the signal and provide mono output for bridged channels 1/2.

Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the output stage of that source.

-You can also feed the SAME signal to both left and right inputs via a Y-adapter RCA cable.

-Connect the mono speaker positive terminal to the RIGHT +, and its negative terminal to LEFT

-as shown.
