professional audio installation technician before installing any
mobile audio components. Be careful and take your time. Disconnect
the power source (battery) before installing. Do not let wires make
contact with metal edges, sources of moisture, or hot engine
components.
Installation:
We recommend 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. This has an in-line 5 amp fuse for protection.

Preamp Level Audio Connections Zone 1, Zone 2, and Subwoofer RCA preamp outputs are labeled as
such. These are intended to be connected to external amplifiers (not included).

Installation
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 (refer to Page 21). We recommend starting with 100Hz for the low pass crossover point.
This unit offers zone control to balance the sound level between different zones. The zones are designated by the zone 1 & zone 2 RCA outputs (using external amplifiers). For example, if using in a boat, a passenger area can be designated as zone 1 and a wakeboard tower speaker could be designated as zone 2, allowing lower or muted volume in the passenger area zone 1 and more volume at the wakeboard speakers zone 2. Each zone can also be independently tuned to achieve the best sound output for different size or style speakers. Example, if the boat has 6.5in speakers connected to zone 1, the HPF may be set to 120Hz high pass to reduce distortion from low frequency reproduction and if zone 2 has 8in wakeboard tower speakers it can be adjusted to play a full range audio signal. (See page 21 for more information.) The volume knob will control both zones and the individual zone 1 & zone 2 buttons allow adjustment of each zone independently.( see page 8 ) A full scale cutout template can be found at mbquart.com/product-manuals/ Please print the template out or use the provided dimensions shown below for easy installation.
