ELECTRICAL CONNECTIONS
Disconnect battery before making any electrical connections.
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 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.
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.
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. Activated by positive or negative input.
