INSTALLATION

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. DO NOT install the fuse at this time.

5.Prepare the BLACK wire (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.

6. Prepare the REM turn-on wire for connection to the amplifier by stripping 1/4" of insulation from the wire end. Using the fully insulated connector provided, crimp the wire into the connector. Insure the insulation on the wire is covered by the insulated connector and no bare wire is visible. Slip the connector over the REM terminal on the

amplifier. 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 accessory 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.

CAUTION: To prevent damage to the unit and/or personal property, only use a fully

!insulated connector when connecting to the REM terminal. The connector supplied is only for use with 14-18 gauge wire.

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 the source signal to the amplifier by plugging the RCA cables/high level inputs 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.

NOTE: Follow the diagrams for proper signal polarity.

CAUTION: These amplifiers are not recommended for impedance loads below 2Ω

!stereo and 4Ω bridged (mono).
