Important installation
considerations for using
this amplifier.
SHOCK HAZARD! Do not open the case
of this product.
There are dangerous
voltages present within the unit. There are
no user-serviceable parts within the unit.
The fuse rating for the amp is 50A
(using two 25A fuses) for the F2600D
and 90A (using three 30A fuses) for
the F3600D. The F5000D’s fuse rating
is 175A (using a single inline ANL type
fuse – fuse and holder are included).
Although sufficient for normal working
conditions, overloading the amp may
result in blown fuses. Please try to
avoid overloading the amp in this
manner.
Your Force Class D amplifier
is designed to run with a min-
imum load of 1 Ohm.
Operating the F2600D, F3600D
or F5000D with a speaker im-
pedance load below 1 Ohm
may result in poor sound qual-
ity and damage to the amplifier
circuitry. Such damage is not
covered under the warranty
for this product.
When making electrical connections
to the amplifier, please observe the
following:
• Always use 4GA or heavier wire for
power and ground connections.
• Wire the amplifier directly to the car
battery. Make sure there is circuit
protection (such as a fuse) on the
positive power lead within 18” of the
battery.
• When making a ground connection,
always use the shortest possible wire
to a good chassis ground point.
• Wire the remote turn-on connection
to the remote turn-on lead of your EQ
or head unit. In some cases, this may
be the power antenna lead of the head
unit.
• Fuses protect BOTH the amplifier
and the electrical system of your
vehicle from faulty conditions. If you
must replace a fuse on the amplifier,
you must use a fuse of exactly the
same type and rating. A different type
of fuse or rating may result in damage
or cause a fire.
Tips for making your system
as save as possible
Do not mistake the input level control
for a volume control! It is designed
ONLY to match the output level of
your audio source to the input level
of your amplifier.
Do not adjust this input level to
maximum unless your input level
requires it.
Ignoring these instructions will result
in an input overload to the amplifier,
and excessive audio distortion. It
can also cause the protection circuit
to engage.
Don't misuse the
level control!
