SYSTEM SETUP

5. Prepare the ground wire for attachment to the ampliﬁer by stripping 5/8" of insulation from the end of the wire. Always

use a wire of the same gauge as the power connection, never smaller. Insert the bare wire into the GND terminal and

tighten the set screw to secure the cable in place. Prepare the chassis ground by scraping any paint from the metal surface

and thoroughly clean the area of all dirt and grease. Strip the other end of the wire, crimp and solder a ring connector.

Fasten the cable to the chassis using a non-anodized screw with a star washer and a nut.

WARNING:

It is important to upgrade the ground

connection between the negative (-) battery post and the

vehicle body or chassis to achieve optimum electrical

performance.

6. Prepare the REM turn-on wire for attachment to the ampliﬁer

by stripping 5/8 inch (15.9mm) of insulation from the end

of the wire. Insert the bare wire into the REM terminal and

tighten the set screw to secure the wire in place. Connect the

other end of the REM wire to a switched 12 volt positive

source. The switched voltage is usually taken from the

source unit's remote amp turn on lead. If the source unit

does not have this output available, the recommended

solution is to wire to an accessory terminal in the car's fuse

block using a relay to isolate the amplifer from the vehicles

accessory circuit. This however will turn the ampliﬁer on and

off with the ignition key, regardless of whether the car stereo

is on or off.

7. Securely mount the ampliﬁer to the vehicle or amp rack. Be careful not to mount the ampliﬁer on cardboard or plastic

panels. Doing so may enable the screws to pull out from the panel due to road vibration or sudden vehicle stops.

8. Connect from source signal by connecting the RCA audio cables to the input jacks at the ampliﬁer.

9. Connect the vehicle speakers. Speakers impedance should never be less than 2 Ohms stereo, 4 Ohms bridged.

For most applications 18 gauge wire is adequate for the speaker leads. For leads in excess of ten feet, 16 gauge

wire is recommended. Strip the speaker wires 1/2" (12.7mm) and insert into the speaker terminal block then tighten

the set screw to secure into place. When wiring the speakers, pay careful attention to the polarity of the terminals on

the speakers and make certain they correspond to the polarity on the ampliﬁer. DO NOT chassis ground any of the

speaker leads as unstable operation or damage to the ampliﬁer and/or speaker may result.
