INSTALLATION

3.Trim the RED wire (power cable) within 18" of the battery and splice in a inline fuse holder. See Specifications for the rating of the fuse to be used. DO NOT install the fuse at this time.

4.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.

5.Prepare the BLACK wire (Ground cable) 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:Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30"(76.2cm).

6.Prepare the REM turn-on wire for for attachment to the amplifier by stripping 5/8" of insulation from the end of the wire. Insert the bared 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 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 plugging the RCA cables into the input jacks at the amplifier.

9.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.

10.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. Install inline fuse near battery connection.

NOTE:Follow the diagrams for proper signal polarity.

CAUTION:These amplifiers are not recommended for impedance loads below 2 stereo and 4 bridged.
