Wiring and Connections

• MB Quart recommends wire-to-wire connections such as power, ground and speaker wiring are soldered and protected with either heat shrink tubing or high quality electrical tape.
• The main (yellow) power wire should be connected to a source with at least 10 amps of additional current capability to support the unit.

Preamp Level Audio Connections

• Front and rear RCA preamp outputs are labeled as such. These are intended to be connected to external amplifiers, not included.
• Subwoofer RCA outputs (green RCAs) are mono and paralleled. They are identical subwoofer audio signals. Their frequency range is controlled by the low pass crossover and the subwoofer level control. Both are found in SETTINGS. See Page 18. We recommend starting with 100Hz for the low pass crossover point.
• The unit offers a zone control feature to balance sound levels between different zones. The front and/or rear RCA outputs (using external amplifiers) are one zone. The source unit's built-in power is the other zone. An example is a boat having separate volume control of amplified wakeboard tower speakers versus cabin speakers positioned closer to listeners using the unit's built-in power. Zone level control is found in SETTINGS. See page 18. Subwoofer RCA outputs or speaker-level outputs are unaffected by the zone level control. All work with the main volume.
