WIRING INSTRUCTIONS
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 #10 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 (#10 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 ap 12V 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 # 18 gauge. For leads is excess of 10 feet # 12 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.
