Wiring and Connections
● 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).
*Refer to Page 25 for aux trigger functionality.
** Refer to Page 26 for RGB output functionality.

Installation
6.50 Inches
(165 mm)
8.25 Inches
(210 mm)
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.
● 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 )
