3. Strip 1/2" from the battery end of the power cable and crimp a large ring
terminal to the cable. Use the ring terminal to connect to the battery
positive terminal. Do not install the fuse at this time.
4. Prepare the Ground cable for attachment to the amplifier by stripping 1/
2" of insulation from the end of the wire. Insert the bared 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.
5. Prepare the REM turn-on wire for connection to the amplifier by stripping
1/2" of insulation from the wire end. Insert the bared wire into the REM
terminal and tighten the set screw to secure the cable into 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 auto antenna or
the accessory lead. If the source unit does not have these outputs
available, the recommended solution is to wire a mechanical switch in
line with a 12 volt source to activate the amplifier.
6. 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.
7. Connect the source signal to the amplifier by plugging the RCA cables/
high level inputs into the input jacks at the amplifier.
8. Connect the speakers. Strip the speaker wires 1/2" and insert into the
speaker terminal and 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 may result.
9. Perform a final check of the completed system wiring to ensure that all
connections are accurate. Check all power and ground connections for
frayed wires and loose connections which could cause problems.
