The quality of installation may affect the performance and reliability of your Crossfire product. If you have any doubts or questions regarding installation, you may
wish to contact your authorized Crossfire dealer. Remember to follow all wire and fuse requirements suggested in this manual. Warranty may void if proper
installation technique is not used (refer to warranty section in the rear of this manual).

Appropriate mounting is very important for prolonged life expectancy of any amplifier. Select a location of applicable space that allows 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 heatsink 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 heat when mounting the amplifier
in an enclosed or restricted area.
Avoid slipping and scratching your new Crossfire amplifier by pre-drilling the mounting holes with either a 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.
