Appropriate mounting is very important for prolonged life expectancy of any amplifier.
Select a location of applicable space that allows for sufficient airflow and provides
protection from moisture. Keep in mind that an amplifier should never be mounted upside
down. Upside down mounting will compromise heat dissipation through the heatsinks and
will engage the thermal protection circuit much sooner. Excessive heat can shorten your
amplifier's life. To maximize heat dissipation, be sure to leave at least 2.5 inches of
clearance around the amplifier. Fans should be used in correspondence with an escape
duct for the heat when mounting the amplifier in an enclosed or restricted area.
Avoid slipping and scratching your new Crossfire BMF amplifier by pre-drilling the mounting
holes with either an 1/8" or 3mm diameter drill bit when using the screws supplied in the
accessory kit. Always investigate the mounting area thoroughly for electrical wires, vacuum
lines, and brake or fuel lines before you start to prevent any potentially expensive mistakes.

All Crossfire amplifiers are designed to work within 10.5 to 16 volts DC. Therefore,
as a precaution the vehicle's electrical system should be checked for correct
voltage supply with the help of a voltmeter. First, connect the test leads of the
voltmeter to the battery terminals with the ignition of the vehicle in the off position.
The voltmeter should read no less than 12 volts. Next check the voltage of the
battery with the engine running between 1500 and 2000 rpms. The voltmeter
should now read between 13.5 and 14.5 volts. If your vehicle's electrical is not up
to these specifications, we recommend having it checked by an automotive
mechanic before you further the installation.
