3.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 ampli- fier. 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 screw.

4.Prepare the REM turn-on wire for connection to the amplifier by stripping 5/8" 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 amplifier.

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

6.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.

7.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.

8.After the final inspection is complete, install the power fuse and enjoy listening. During the initial listening period, you may need to “fine tune” any phasing and level settings within your particular vehicle. To aid in this procedure, play a track with high musical content and cruise around your neighbor- hood. After fully evaluating the transient response of your system and making any final adjustments, all your neighbors within a 1 mile radius will assume that you have just success- fully completed another upgrade to your audio system for which they will probably spill thumbtacks on your driveway.
