Speaker Wiring

The Very Basics
No speaker wires can be shorted to, or touching either ground or each other. This will put
the amp into protect and may damage the amplifier. When bridging the left and right
channels of any ST-D SQ MINI amplifier, you use the left channel (Ch1) positive and the
right channel (Ch2) negative, as indicated on the chassis by the speaker terminals

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 150 watts (ST-64D) and 240 watts
(ST-104D) 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.
