POWER CONNECTION
The battery terminal (BATT) must be connected directly to the positive terminal of the
vehicle battery to provide an adequate voltage source and minimize noise. Connecting
the battery terminal lead to any other point (such as the fuse block) will reduce the power
output and may cause noise and distortion. Use only #4 gauge or thicker (smaller gauge#)
wire for this lead and connect it to the terminal of the battery after all other wiring is
completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation of the
amplifier. Use a wire of the same gauge as the power connection (#4 or thicker) and
connect it between the ground terminal(GND) of the amplifier and a metal part of the
vehicle close to the mounting location. This wire should be as short as possible and any
paint or rust at the grounding point should be scraped away to provide a clean metal
surface to which the end of the ground wire can be screwed or bolted.
REMOTE TURN-ON CONNECTION
The amplifier is turned on by ap12V to the remote turn-on terminal (REM). The wire
lead to this terminal should be connected to the "Auto-Antenna" lead from the car stereo
which will provide the +12V only when the car stereo is turned on . If the car stereo does not
provide an "Auto-Antenna" lead, the remote turn-on lead may be wired to an "Accessory"
or "Radio" terminal in the car's fuse block. This will turn the amplifier on and off with the
ignition key, regardless of whether the car stereo is on or off. The remote turn-on lead does
not carry large currents. So #20 gauge wire may be used for this application.
SPEAKER CONNECTIONS
Depending on the type and number of speakers used with the amplifier wire them to the
speaker terminals as per the appropriate wiring diagram. For most applications # 18 gauge
wire should be used for the speaker leads but in no case thinner than # 20 gauge. For leads
is excess of 10 feet #16 gauge is recommended. When wiring the speakers, pay careful
attention to the polarity of the terminals on the speakers and make certain they correspond
to the polarity of the corresponding terminals on the amplifier. Do not ground any speaker
leads to the chassis of the vehicle.
