CROSSFIRE LIMITED WARRANTY
This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state. This warranty
is only valid on Crossfire products purchased in the U.S.A. from an authorized Crossfire dealer. All Crossfire amplifiers
are warranted to be free from defects in materials and workmanship under normal use and service for a period of (3) years when
the unit is installed by an authorized Crossfire dealer. Non-authorized dealer installed products carry a (1) year parts and labor
limited warranty. The extent and conditions of Crossfire’s limited warranty are as follows:
i. Crossfire will either repair or replace (as its option) any unit which Crossfire has examined and found to be defective
and under warranty, to the original purchaser, provided the defect occurs within (3) years of the date of purchase when
installed by an authorized Crossfire dealer. This warranty includes both parts and labor and applies to the original pur
chaser only.
ii. Crossfire will either repair or replace (at its option) any unit which Crossfire has examined and found to be defective
and under warranty, to the original purchaser, provided the defect occurs within (1) year of the date of purchase when
the unit is installed by a non-authorized Crossfire dealer. This (1) year warranty includes both parts and labor and
applies to the original purchaser only.
iii. This warranty will be void to any unit found with the original serial number removed, altered or defaced. All units re
ceived by Crossfire for warranty with their original serial numbers removed will not be repaired and
will be returned to the sender Freight Collect.
iv. The provisions of this warranty shall not apply to products used for any industrial, professional or commercial pur
poses or any other uses for which it was not designed or intended.
v. This warranty does not cover cost for removal of product for repair or reinstallation of product after repair, nor does it
cover the cost of returning the product to Crossfire’s service center for repair.
vi. This warranty does not apply to repairs or replacements necessitated by any cause beyond the control of Crossfire
Including, but not limited to, any malfunction, defect or failure caused by or resulting from unauthorized service or parts,
improper maintenance, operation contrary to furnished instructions, shipping or transit accidents, incorrect power line
voltages, fire, flood or any other acts of nature, or normal wear and tear.
vii. The foregoing is in lieu of other expressed warranties and Crossfire does not assume or authorize any party to as
sume for it any other obligation or liability. The durations of any warranties, which may be implied by law (including the
warranties of merchantability and fitness), is limited to the term of this warranty. In no event shall Crossfire be liable for
special, incidental or consequential damages arising from obligations under this warranty due to cause beyond its con
trol. Some states do not allow limitations on how long an implied warranty lasts and/or do not allow the exclusions or
limitation of consequential damages, so the above limitations and exclusions may not apply to you.
viii. Return policy.
Your unit will be serviced free of charge on an in-warranty basis only. If improper operation occurs, contact your authorized
Crossfire dealer for assistance with the return and factory repair of your Crossfire product. If an authorized Crossfire dealer is
not available, the following procedure must be followed: phone us at [phone] or fax in your name, address, telephone
number and the model number of the item(s) to be returned to receive a Return Authorization Number to [phone]. Your
return authorization number must be clearly written on the outside of the packing box returned to Crossfire. All returned products
must be accompanied with a DATED proof of purchase invoice or the product may be subject to costs of parts and labor. Return
the unit in the original protective carton or a carton with ample protection. Please include a brief description of the problem and
send your repair to:

IMPORTANT!!
REMEMBER !!
The majority of failures seen with Class D amplifiers are due to people using them in vehicles without the proper electrical con-
siderations. The common misconception about Class D amplifiers contributes to this problem, since the BMF1000D is Class D
amplifier and very efficient, the misconception is that it doesn’t pull amounts of current. This is partly true. A BMF1000D is capable
of drawing 120 amps of current at max draw. At 120 amps of current to produce over 1000 watts is very efficient, while some class
A/B amplifiers need over 200 amps to produce the same power. A normal stock automobile sees it difficultly, 120 amperes is a
very high amount of current and posses a very high strain on it’s electrical system.
We at Crossfire strongly suggest using one dedicated, high quality, battery per BMF1000D or per two BMF500M amplifiers. We
also recommend upgrading the vehicles alternator whenever possible.
It is very important to keep your battery voltage above 11 volts and as close to 14.4 volts as possible. Not only do you get more
power at 14.4 volts but you are risking serious damage to your amplifier below 11 volts. Ohms law states that current equals power
(watts) divided by voltage. This means that current and voltage are inversely proportional, in other words as your battery voltage
falls your amplifier has to draw more current to make the same amount of power. At a certain point the amp draws so much current
that damages components in the input section. This is very common in all Class D amplifiers. The solution is to keep your battery
voltage between 12 volts and 14.4 volts. If you follow the tips below you will get the best of most reliable performance from your
BMF amplifiers.
1. Make sure the automobile has an electrical system that will support the audio systems current draw.
2. Upgrading your alternator for multiple amplifiers is recommended
3. Use at least one (1) high quality battery per BMF1000D or per two BMF500M, Two (2) batteries per BMF1700D.
4. For runs of 20ft or less use at least one 4 awg power wire and one 4 awg ground wire per BMF1000D, 4 awg for the BMF500M,
1/0 awg for BMF1700D. If you are using one wire with a distribution block for multiple amps, make sure to use a larger gauge wire
for the main feed.
Be sure to test battery voltage at the amplifier terminals white the system is playing at high volume. Make sure this reading stays
as close to 14.4 volts as possible, if this measure is below 12 volts see above tips or email
