MOUNTING
The unit is waterproof and may be located under hood in the engine compartment or other areas.
Allow clearance for wiring. Inspect behind mounting area for clearance.
ELECTRICAL CONNECTIONS
Electrical connections to the unit are made using butt splices (not supplied). The butt splices
need to be waterproof when unit is mounted under hood or other weather susceptible areas.
A
label on the unit identifies each lead function. The power supply of the unit must be capable of
delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation.
The unit is provided with an in-line fuse.
Failure to adequately crimp splices can result in improper operation or burning the wire.
Wire Size and Termination - The diagram shows the minimum wire size used for each connec-
tion, along with recommended lead color. If the wire is longer than 15 ft. use the next larger wire
size. Use only high quality crimp connectors for installation on the vehicle.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.

SERVICE
This unit is designed to provide years of reliable service under even the worst conditions. Many
times there may appear to be a problem with the unit when the true problem is in the speaker or
improper installation. The following chart shows typical symptoms and possible causes.
A blown in-line fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is
shorted the fuse will blow before the unit is damaged. Disconnect the speaker leads and replace
the fuse. If the power indicator light on the unit comes on with power applied it is OK. Check the
speaker or leads for possible shorting.
