3) Trim the power cable within 18 inches (45.7mm) of the positive battery
post and splice in a in-line fuse holder. DO NOT install the fuse at this
time.
4) Strip 1/2 inch (12.7mm) from the battery end of the power cable and
crimp a large ring terminal to the cable. Connect the ring terminal to
the positive (+) battery post.
5) Prepare the ground wire for attachment to the amplifier by stripping 5/8”
of insulation from the end of the wire, 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 and attach a ring connector. Fasten the cable to the chassis using a
non-anodized screw and a star washer.
NOTE: 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 posi-
tive source. The switched voltage is usually taken from the source unit’s remote amp on lead. If the
source unit does not have this output available, the recommended solution is to wire a mechanical
switch in line with a 12 volt source to activate the amplifier.
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
or by connecting speaker level signal to RCA audio cables and/or RCA jacks.
9) Connect the car speakers. Speakers should be 4 Ohms. If connecting one speaker per channel as
shown in the diagrams (except where noted on D6 1200.1). Strip the speaker wires 1/2” (12.7mm)
and insert into the speaker terminal block, then tighten the set screw to secure into place. Be sure
to maintain proper speaker polarity. DO NOT chassis ground any of the speaker leads as unstable
operation or damage to the amplifier and/or speaker may result.
