PL EASE READ ALL INSTRUCTION S BEFORE INSTALLING!

The quality of installation may affect the performance and reliability of your Crossfire product. If you have any doubts or ques­tions regarding installation, we recommend that you 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 the warranty
section in the rear of this manual).

MOUNTING

Appropriate mounting is very important for prolonged life expectancy of any amplifier. Select a location with ample 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 heat sink 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 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, as to prevent any potentially expensive mistakes.

Incorrect Mounting

Heat is trapped inside the amplifier, shortening the life

of the electronic components.

Incorrect Mounting

Heat is lifted from the amplifier heat sink.

iNPUT SENSITIVITY

This amplifier may be equipped with an input sensitivity switch(es) (fig. 1&2) which are meant to assist in producing its rated
power when using a head unit with low voltage preamp outputs. For example, if your model amplifier has this switch(es) and is
affixed to the “x3” position (fig. 1) the amplifier is most sensitive to an input voltage range from 390mV-9V, where as when set to
the “x1” position it is most sensitive to an input voltage range from 130mV-3V. However, this does not mean you can connect or
splice speaker level outputs from a head unit to the RCA terminals of the amplifier.

CAUTION

fig. 1 fig. 2

This amplifier is equipped with an input

sensitivity switch which is meant to

assist in producing its rated power

when using a head unit with low

voltage preamp outputs. However

this does not mean you can connect or

splice speaker level outputs to the

RCA terminals of the amplifier.
