Rockford Fosgate 250, 360, 400, 500, 600, 800, 1000 manual

4.Prepare a length of cable to be used for the ground connection. Strip 5/8" of insulation from the end of the cable as described above and connect to the appropriate terminal of the amplifier. Prepare the chas- sis ground by scraping any paint from the metal surface and thorough- ly 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 strip- ping 1/4" of insulation from the wire end and crimping an insulated spade connector in place. Slide 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 signal 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 ampli- fier.

6.Securely mount the amplifier (with supplied screws) to the vehicle or amp rack. Be careful not to mount the amplifier on cardboard or plas- tic panels. Doing so may enable the screws to pull out from the panel due to road vibrations or sudden vehicle stops.

7.Determine the number of inputs needed to drive the amplifier and move the input switch to the desired setting (Power 400 & Power 800 4-channel amplifiers only.).

8.Connect the source signal to the amplifier by plugging the RCA cables into the input jack(s) at the amplifier.

9.Connect the speakers. Strip the speaker wires 5/8" and insert into the appropriate terminal on the amplifier. Insert the bared wire 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 from road vibrations.
