IMPORTANT
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.
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.

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.

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 in 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.

POWER WIRE & FUSE The proper wire size is very important for an amplifier capable of these power levels. The following are the recommended fuse values and wire gauge for lengths up to 20ft. Model Wire Fuse BMF1000D 4awg. 100amp BMF600D 8awg. 60amp
POWER Power wire needs be connected directly to the battery using the wire requirements listed above. Never use the fuse box or any other wire as a source for the power for an amplifier. Before you start, choose the easiest path to run the wire from the battery to the amplifier. Generally, try to keep the power wire on the driver's side of the vehicle (See Signal Inputs & Outputs for explanation). Use the following rules for running the power cable through the vehicle:
1. Use grommets when passing the power wire through any metal wall of the vehicle.
2. Avoid sharp corners or sharp body parts that may easily cut through the insulation on the wire.
3. Avoid running the power wire over engine components and near heater cores.
4. Avoid the gas, brake and clutch pedals and their mechanisms.
5. Use an inline fuse to eliminate the risk of a fire caused by a short in your power wire.
6. Connect the fuse holder as close to the battery positive as possible.
Once the wire has been run, connect the wire to the battery terminal. As a precaution, leave the fuse out until all other wire connections are made.
GROUND
The wire used for ground should be of the same gauge as the power wire. Just make sure that you choose a different color (generally black) so that you don't reverse the polarity at the amplifier terminals. Follow the rules below for connecting the ground wire properly:
1. Avoid using seat bolts, seatbelt bolts, and fender wells for ground.
2. Choose a metal area close to the amplifier that appears to be a good of ground, such as the floor.
3. Investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Please note that if you are installing multiple high power amplifiers into the vehicle, you must upgrade the ground strap from the battery to the frame and the frame to the body.
Directions:
1. Find a nut and bolt to fit the ring terminal you have chosen.
2. Drill a hole just large enough for the bolt to fit through at the source of ground.
3. Use either a wire brush or sandpaper to eliminate unwanted paint around the hole you have drilled as to supply a better contact for your ground.
4. Terminate the ground wire to the ring terminal and attach it to the bare metal using the nut and bolt. It is very important for this connection to be solid.
5. Spread silicon over the screw and bare metal to prevent rust and possible water leaks.
REMOTE TURN-ON
In between the power and ground of the amplifier is a remote turn-on terminal. This terminal must be connected to a switched +12 volt source to make the amplifier operational. Typically, remote turn-on leads are provided at the head unit that will turn on and off the amplifier in correspondence with the source. This means you will most likely have to remove the head unit from the dash to find the source +12V output wire.
Once the head unit is pulled from the dash, locate the remote turn on wire. The majority of vehicles will be using an after market head unit when using an amplifier. These after market head units generally use a blue or a blue with white wire as the remote turn on for the amplifiers. However, when using a factory radio, the power antenna wire should be as a turn on lead if applicable (colors will vary from make/model). Only if a lead is not available at the source, a switched +12 volt supply, such as a toggle switch, should be applied.
Use a minimum of 18-gauge wire, preferably blue, to connect the amplifier to the head unit. If possible, route this wire along side of the power wire using the same precautions. Connect the remote output of the head unit to the wire using a barrel connector or a mating terminal as required by the source unit. You can solder these wires together, but be sure to use heat-shrink over the connection. Do not place the radio back into the dash yet.
