MONO CHANNEL CLASS "D" AUTOMOTIVE AMPLIFIER G1-1200 / G1-2000 / G1-3000 INSTRUCTION MANUAL
CONGRATULATIONS ON YOUR PURCHASE Your new high fidelity mono block amplifier is designed to deliver maximum enjoyment and one year of trouble free service. Please take a few moments to read this manual thoroughly. It will explain the features and operation of your unit and help insure trouble free installation.
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.
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.

POWER SUPPLY CONNECTIONS The Class "D" amplifier is designed to work within 10 to 16 volts DC. Before any wires are connected, the vehicle's electrical system should be checked for correct voltage supply with the help of a voltmeter. First check the voltage at the battery terminals with the ignition in the off position. The voltmeter should read no less than 12 volts. Next, check the battery with the engine running between 1500 and 2000 rpm. The voltmeter should now read between 13.5 and 14.5 volts.
