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. Assure adequate ventilation to prevent overheating. Allow
clearance for wiring and radio adjustment. Inspect behind mounting area for clearance. Mark
the location of the mounting holes to be drilled.
Drill 4 holes (up to 1/4" diameter) to mount the amplifier to the vehicle. Install the removable
pressure connector and make all electrical connections before final mounting (See
ELECTRICAL CONNECTIONS – Amplifier). The connector can be secured with the two
locking screws. Then mount the amplifier to the vehicle using appropriate hardware (not
supplied).
ELECTRICAL
CONNECTIONS - Amplifier
Electrical connections to the
amplifier are made using a
removable pressure connector
located on the amplifier. A
label on the unit identifies the
terminal function. You should
install the connector on the
unit before wiring. If the unit
needs service the connector
can be easily removed without
unwiring the connector.
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 preferred
source is directly at the
vehicle battery. The unit is
internally fused.
Attach leads by stripping 3/8", inserting into connector 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.
Wire Size and Termination
- The diagram shows the minimum wire size used for each
connection, along with recommended lead color. If the wire is longer than 10 ft. use the next
larger wire size. The power lead pairs can be extended with single #12 AWG lead wire. Use
only high quality crimp connectors for installation on the vehicle.
Please note that three leads are connected to the speakers – one common lead to the
negative of both speakers and one lead to each positive speaker terminal. This is necessary
for dual mode operation.
