MOUNTING
Amplifier
Select a location for the amplifier in an area such as the driver compartment firewall, under a seat,
etc. Mounting the amplifier in the engine compartment or in an area directly exposed to weather
is not recommended. Allow clearance for wiring. Inspect behind mounting area for clearance.
Install the terminal block plug and make all electrical connections before final mounting. Use #8
screws (supplied loose) for mounting.
Speaker
The speaker is weather resistant and is intended to be mounted on the outside of the vehicle or
under front hood. Mount the speaker facing forward and as far forward on the vehicle as possible
to minimize sound exposure to occupants. Choose a location that minimizes obstructions in front
of the speaker to maximize forward sound. Attach the speaker to a sturdy part of the vehicle to
prevent vibration and possible damage. Attach the speaker angled slightly toward the road so the
front openings will drain off any fluids. Cover openings of speaker while drilling any holes.
Switch Panel
Mount the switch panel underneath the vehicle dash board using #8 screws (supplied loose).
Locate the panel away from the driver’s or passenger’s legs. Allow clearance for wiring. Inspect
behind mounting area for clearance. Make all electrical connections before final mounting.
ELECTRICAL CONNECTIONS
Amplifier
Electrical connections to the amplifier are made using a removable terminal block plug (supplied
loose) located on the side. A label on the amplifier identifies each terminal function. You should
install the plug on the amplifier before wiring. If the unit needs service the plug can be easily
removed without unwiring. The amplifier is fused near the connector. 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. Most vehicle horn circuits with relays provide adequate power
on the vehicle horn side of the relay. However do not provide power to both the vehicle horn and
this amplifier from one horn relay circuit as this will exceed circuit rating.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
Attach leads by stripping 3/8", inserting into plug and clamp by tightening screw. Make sure the
screw is tight and the wire can't be pulled out. Failure to adequately tighten the screw can
result in improper operation or burning the connector and wire.
Switch Panel
Electrical connections to the switch panel are made using 3/16” quick-connect terminals (supplied
loose).
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 10 ft. use the next larger wire
size. Use only high quality crimp connectors for installation on the vehicle.
