INSTALLATION
MOUNTING:
1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1.
2. Once the location has been determined, place the amplifier into position. Using a felt tip
pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as
a template for drilling. It is very easy to damage the amplifier surface in this manner.
3. Remove amplifier. Drill four 3.5 m/m holes into mounting surface. If you want to mount
the amplifier to MDF or wood panel, drill four 3.0m/m diameter holes into mounting surface.
4. If possible, test the system to ensure it is operating correctly before final mounting of
the amplifier.
Mount the amplifier using the supplied 4 self tapping screws.

SPEAKER WIRING
The Class "D" amplifier is a SINGLE CHANNEL dedicated subwoofer amplifier. Unlike
other amplifiers, the Class "D" operates as a single channel and cannot be bridged.
Don't be fooled by the outputs. Two outputs are used strictly for convenience and are
paralleled internally on the amplifier. This means that if both outputs are used with one
driver each, the amplifier sees the same load as if the same drivers are connected to
only one output terminal. See diagram below.
