2 CHANNEL / 4 CHANNEL / 5 CHANNEL AUTOMOTIVE AMPLIFIER G2-600 / G2-800 / G2-1200 G4-600 / G4-800 / G4-1000 G5-900 INSTRUCTION MANUAL
Congratulations on your Purchase Your new high fidelity bridgeable/stereo amplifier is designed to deliver maximum enjoy ment 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. Features • • • • • • • • • • • • Four Class ''AB'' High-Current Dual Discrete Drive Stages. Class ''AB'' Technology MOSFET PWM Power Supply. Bridgeable & TRI-Mode Operation.
• NEVER operate the amplifier without the proper power and ground wire, 10 gauge minimum. • NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will blow instead of the wire burning up. Using other than the recommended fuse ratings at the battery and at the amplifier may cause damage to the amplifier and will void your warranty.
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.
CONNECTIONS INPUT CONNECTIONS This amplifier will accept low level inputs only. Low level is the same as line level. The low level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs. If not, you can use a "high to low converter" available through your local car audio shop. Connect the low level/line level RCA cables from the head unit, or signal processor, to the line level input on the amplifier. See Fig.

SPEAKER CONNECTIONS This amplifier can operate in one, two or three channel mode. The minimum impedance for single channel (bridged/mono) operation is 4 or 8 ohms. Tri channel power is referred to stereo and mono at the same time. Minimum impedance remains the same for three channel (front /subwoofer) systems as long as proper passive crossovers are used. Connect right and left speaker wire to corresponding speaker output terminals of the amplifier.

ADJUSTMENTS 1.Set to the "H.P.F" position when the amplifier is used to drive a tweeter/midrange system. The frequencies below the crossover point will be attenuated at 12dB/octave. Permits adjustment of the crossover frequency ,by rotating the knob to select any frequency between 80Hz to 1.2kHz & 50Hz to 500Hz as the crossover point. 2.Set to the "L.P.F" position when the amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12dB /octave.
