Never mount the car amplifier in a location that is subject to direct sunlight or exposed to moisture.
Never mount the car amplifier up side down, this will cause the heat to rise back into the amplifier causing thermal shutdown or possible permanent damage.
Be sure to mount the amplifiers to a strong, solid surface which will not give way under the stress of a sudden stop or accident.
Negative battery terminal must be disconnected before any electrical connection are made.
Be sure choose a location that provides substantial ventilation for the amplifier.
The location chosen should provide at leat 2 of clearance above the amplifier for adequate ventilation.
If the amplifier is to be mounted vertically be sure that it is in a place where adequate air will follow along the length of its heatsink fins for cooling.
Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or other critical parts of your car when installed.
