POWER CONNECTION LEADS
Connect the +12V power input lead only after all other leads have been
connected.
Be sure to connect the ground wire of the unit securely to a metal part of the car.
A lose connection may cause a malfunction of the amplifier.
REM: The unit is turned on by ap12 Volts to this terminal. This terminal
does not draw heavy current like the Power Terminals so a thinner
connecting wire is acceptable. Standard 18 GAUGE is fine and the standard
color is yellow .lf the radio is equipped with a Power Antenna control wire, it can
drive this terminal . If the Power Antenna wire is already in use, you can still
splice into it. With this method, the unit will turn on automatically with the radio.
Use the power supply lead with a fuse attached whose value is the same as
original fuse.
Place the fuse in the power supply lead as close as possible to the car battery .
During a full power operation, maximum current will run through the system
Therefore, make sure that the leads to be connected to the +12V and GND
terminals of the unit respectively must be larger than 10-Gauge ( AWG.10).

POWER CONNECTION
The battery terminal (+12V) 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 thic-
ker)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 #18gauge wire should be used for the speaker leads but in no case
thinner than #20 gauge. For leads in excess of 10 feet # 16 gauge is recommen-
ded. When wiring the speakers, pay careful attention to the polarity of the termi-
nals on the speakers and make certain they correspond to the polarity of the c-
orresponding terminals on the amplifier. Do not ground any speaker leads to the
chassis of the vehicle.
INPUT CONNECTIONS
This amplifier features low-level input capability.
If the car stereo does not provide low-level outputs, the amplifier may be connec
-ted via the speaker (high-level) outputs from the stereo with a AUTOCRAFT line
converter.
