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.

IMPORTANT

Please read all instructions before installation!

OPERATION

Both the Crossfire BMF1000D and BMF600D are single channel, dedicated subwoofer amplifiers. Unlike other Crossfire BMF amplifiers, both these amplifiers operate

as a single channel, therefore one amplifier cannot be bridged by itself. Do not be fooled by the two sets of speaker outputs. Two outputs are provided strictly for

convenience and are paralleled internally on the circuit board of the amplifier. This means that if both outputs are used with one driver each, the amplifier sees the

same load as if the same two drivers are connected to only one output terminal.
