Installation - General
WARNING! Before driving the amplifier mounting screws through any surface, be sure of what is behind that
surface. Check for the gas tank, brake lines, and any vehicle wiring harness. Never run wires outside or under
the vehicle or where they could become broken or interfere with the safe operation of the vehicle.
Before You Install
Before you install the unit, disconnect the negative (–) battery cable in the engine compartment of the vehicle.
Doing so will prevent damage to both the electrical system of the vehicle and the amplifier during installation.
Battery and Charging System
In order for the amplifier to function correctly, the electrical system of the vehicle should be professionally
checked for overall electrical capacity. When used, the amplifier will increase the demand on the battery and
alternator. Therefore, both should be thoroughly evaluated before installing the amplifier to ensure they are in
normal operating condition and able to handle the increased demand the amplifier will present to the vehicle’s
electrical system.
Wire Routing
Do not run the power wire near any low-level signals or audio cables such as the RCAs from the head unit.
Noise can be introduced into the amplifier when this occurs. It is helpful to diagram the wire layout first
before any installation is initiated.
Choose the Mounting Location
Plan your installation so that the amplifier is mounted where adequate ventilation is available. Never mount
an amplifier in the engine compartment of a vehicle!
WARNING! Before driving the mounting screws through any surface, be sure of what lies behind that
surface. Check for gas tank, brake lines, and any vehicle wiring harness.
Passenger and Trunk Compartment Mounting
If the amplifier is mounted under a seat, be sure that the vents do not become blocked. Do not allow seat
padding or other obstructive material to press down on the amplifier.
All Boston GT
®
amplifiers have top panel controls. If the amplifier is mounted under a seat, position the
amplifier so the cover panel can be removed with the seat forward or back to allow adjustment of the audio
settings.
When mounting in a trunk, choose a location that will be protected from sliding cargo or other materials. Mount
the amplifier to solid surfaces only. Do not mount to plastic trim panels. Do not mount the amplifier with Velcro,
double-stick tape, or by wedging into position. Amplifier should be mounted using the movable mounting feet
and the provided mounting screws.
Multi-Position Mounting Feet
The mounting feet are designed to slide in both directions to clear installation obstructions on the mounting
surface.
Venting (Side and Rear)
The cooling vents must be kept clear of obstructions once the amplifier is installed. If the vents are obstructed,
this could lead to premature thermal shutdown or amplifier failure.
