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).
The BMF MOSFET amplifiers will reach their potential output into either a 2 ohm
stereo load or a 4 ohm bridged load. A lower impedance can send the amplifier
into current protection and possibly damage the circuitry. To prevent damage, use
the following formulas to help you calculate the load you are placing on the
amplifier. If you have any difficulties, please contact your local Crossfire dealer of
Crossfire's Technical Assistance at 562-906-0800.
