ELECTRICAL CONNECTIONS

Disconnect vehicle battery before making any electrical connections.

Electrical connections to the amplifier are made using the wiring harness supplied. If the amplifier needs service the connector can be easily removed without unwiring the harness. The power supply for the amplifier must be capable of delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred source is directly at the vehicle battery. A fuse on the unit protects from overload.

Wire Size and Termination - The diagram shows the minimum wire size used for each connection. If the wire is longer than 10 ft. use the next larger wire size. Use only high quality crimp connectors for installation on the vehicle.

Negative Connection (Black) - Both leads must be used. Connect to negative battery connector or high current buss.

Positive Connection (Red) - Both leads must be used. Connect to positive battery connector or high current buss. A power relay may be used.

Speaker Connection (Brown) - Both leads must be used. Connect 1 lead to each terminal or lead of the speaker. When used with 2 speakers connect each brown lead to both speaker terminals or leads (parallel circuit). Observe polarity (phasing) when connecting 2 speakers.

Optional Radio Input Connection (Blue) - Connect 1 lead to each terminal of the radio speaker or output connector. The input is isolated and polarity is not important. May need to set RADIO VOLUME ADJUST inside the unit.

Optional Auxiliary Input Connection (White) - The Auxiliary Input allows an external source to activate the Siren push button function. The diagram shows a horn ring connection example. Activated by positive or negative input. NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
