Installing the Amplifier
UNIT REQUIRES AIR FLOW: The siren amplifier is cooled by an internal fan.
Do not install it in areas where the air flow is restricted. Do not mount the unit
near a heater duct or under the hood.
UNIT IS NOT WATERPROOF: The siren amplifier is NOT waterproof. The
module must be mounted in a location that is sheltered from falling rain, snow,
standing water, etc.
To install the amplifier:
1.
Select a suitable mounting location for the amplifier. Some possible mounting
locations are in the equipment cabinet, under the front seat, or in the trunk (under
the rear deck, near the rear seat speakers if the vehicle is so equipped). Keep in
mind that the control cable is 15 feet long.
