INSTALLATION
Installing the amplifier watch carefully the
following criteria:
PoSItIon AnD ventIlAtIon
•
never install an amplifier in the engine
compartment or on the firewall.
•
Please be sure to leave breathing room around
the amplifier heat sink so that it can dissipate the
heat it produces efficiently.
•
the amplifier can be installed either horizontally
or vertically.
AMPlIFIeR PRoteCtIon
•
Avoid places where foreign objects can come into
contact with the heatsink or connectors.
•
Avoid installing the amplifier in a position where
it may come into contact with rain water or other
liquids.
•
Keep your installation clear of any parts of the
vehicle that will either endanger your safety or the
safe operation of the vehicle.
•
Do not drill or mount any screws where they
might penetrate the gas tank of your car.
•
Secure the amplifier tightly. An unmounted
amplifier in your car can cause serious injury to
passengers and damage to your vehicle if it is set
in motion by an abrupt driving maneuver or short
stop.

GENERAL WARNING
•
Due to the extreme high power capabilities of
the Dragster DAF amplifiers, we recommend 0
to 2 gauge Power and Ground cables minimum
for typical installations. Be sure to hook up both
Power terminals on the DAF 7001.
•
You must install an additional 200 Amp in-line
fuse in the main power cable and 400 Amp fuse
for the DAF 7001.
•
the DAF 5001 and 7001 are capable of 18vDC
input and will output substantially more power
when powered by 18v. this can be achieved by
wiring three 6-v golf cart or motorcycle style deep
cycle batteries in series.
•
Before you begin with your installation,
disconnect the neGAtIve (-) terminal from your
car’s battery. this safety precaution will avoid
possible short circuits while wiring your amplifier.
Dragster amplifiers operate on 12-volt negative
ground systems only.
We recommend you protect your audio system
with 2 fuses.
one fuse should be located near the car battery.
this fuse near the battery offers protection against
damage from short circuits to the car chassis
between the battery and the amplifier. A second
fuse closer to the amplifier offers additional safety
to the amplifier itself. this fused red power wire
should be attached to the amplifier power terminal
marked 12v+.
the wire should be made of primary cable and
should terminate for connection directly to the
positive terminal of the car battery. Use a spade
plug to attach the wire, which connects to the
amplifier location marked 12v+.
A second black (or blue or clear) color wire
of equal gauge should be used as a ground
connection to a welded chassis member. When
connecting the ground wire make sure that there
is no paint or other insulation blocking a good
ground connection. When installing multiple
amplifiers, mount them in close proximity so that
they can all share the same ground point. Attach
the black ground wire to the amplifier screw
terminal marked GnD (Ground).
We recommend that you use the Dragster cables
and installation kits, which contain all the cabling
and accessories necessary for a good, reliable
installation.
When there is a lack of good ground, heat builds
up at the weakest point which happens to be
the contact screw of the amplifier terminal. over
time the heat generated will begin to melt the
terminal. It is a good practice to feel the power
and ground wires with your hands, near their
amplifier connection after having played the amps
for a while. If the wires feel hot to the touch you
probably have a bad or loose connection. If you
are sure of your connections and the wires still feel
hot to the touch, you should upgrade the gauge of
wire to next heaviest gauge.
the remote turn on connection is located on
the barrier strip next to the power and ground
connections. this connection is responsible for
turning the amplifier on and off with the rest of
the system. A smaller gauge wire can be used
to make this connection to your radio’s power
antenna lead. Should your system not having any
turn on leads, you can wire the remote terminal to
an accessory lead, which turns on, with gauge with
your car ignition.
RCA CONNECTION
Run RCA cables from your sound source to the
inputs of the amplifier. We suggest the use of high
quality shielded RCA patch cords to help to reduce
and eliminate unwanted electrical noise to your
system.
to avoid electrical noise from being injected in
to your sound systems be sure to run the RCA
cables on the opposite side of the vehicle that you
used to carry the power and ground leads of the
amplifier.
•
RCA PReAMP oUtPUt (DAF 2502, 4002, 3001,
5001, 7001). the preamp output is a full range
signal mixed from both input channels. Use this
signal to feed a secondary full range amplifier in
your system.
•
4-ChAnnel RCA InPUt (DAF 1004, 6004). the DAF
6004 four channel RCA inputs which allows you to
have 4 channel balanced and faded signal from
your head unit. If your head unit has only 1 pair
of RCA outputs, you must use a “Y” adaptor to
split the signal to all four input channel.
SPEAKER CONNECTION
GENERAL WARNING
•
DAF amplifier is extremely powerful and can
seriously damage any speakers which are not
specifically designed to handle such high power
inputs. thus, please ensure that your speaker
power ratings and impedance loading match the
amplifier.
•
the speaker terminals can accept 8 gauge wire.

Input gain, subsonic filter, bass focus are
controlled by the Master amplifier.
•
the entire pre amp section of the Sleve amplifier
is bypassed. this is done so all you have to do is
to set the Master amplifier and the Slave amplifier
will match the Master exactly. there is no need
for any manual matching to occur. this ensures
perfect alignment of your system. one Bass Control
knob, plugged in to the Master amplifier will also
control both amplifiers, thereby simplifying your
installation as well.
•
Use the RCA Pre amp output to the Master
Amplifier to feed secondary Full Range Multi-
Channel amplifiers for a Multi-Amp system.
•
Set Master Amplifier to “MASteR”. Set Slave
Amplifier to SlAve
•
Set Phase shift on both amps to same position.
•
Set all crossover setting, bass equalizer, subsonic
filter, bass focus on MASteR amp to desired
settings.
•
Use a standard RCA cable to connect MASteR oUt
of amplifier #1 (Master) to SlAve In of amplifier #2
(Slave).
•
Connect a heavy duty speaker wire between the
neGAtIve terminals of both amplifiers.
•
When bridging two DAF amplifiers, the final
impedance of the bridged channel shall be no less
than 2-ohm.
•
Under no circumstances can you bridge two
different models of amplifiers.

the DAF 6004 is classified as an unbalanced
power amplifier. this means that the power of
channels 1 and 2 is not equal to the power of
channels 3 and 4. though a 4 channel amp, its
purpose and design was to deliver optimum 3
channel system performance. Channel 3 and 4 are
more powerful than channel 1 and 2 and thus
designed for either the subwoofers in a system or
for multiple mid-bass drivers.
All channels are 1 ohm stable in stereo mode and
may be bridged to a 2 ohm mono load.

a 10 times (X) Frequency Multiplier switch that
changes the frequency range to 150hz-4khz (Ch-1
and Ch-2 on DAF 1004/6004). the low Pass can
be changed from 40hz-400hz to 400hz- 4khz
range. this is especially useful for band pass
configurations.

DAF amplifiers feature sophisticated IC controlled
protection circuitry. If the amp goes in to a
diagnostic condition from thermal over load or
speaker short circuit the leD will light and amp will
shut down.
TWEAKING
once the system is operational, the first thing
to do, is set all crossover points to approximate
settings. In the case of the basic sub woofer
system low Pass filter crossover at 100 hz or so.
Set the Bass Boost equalizer controls to 0 dB (Flat
Switch Position).
now you should set the amplifiers input Sensitivity
adjustment. the knob accessible on the side
of the amplifier marked InPUt GAIn adjust
the input sensitivity from 200mv to 6v (DAF
3001/5001/7001) or 300mv to 8v
(DAF 2502/4002/1004/6004).
to adjust the input sensitivity, turn the control
using a small flat head screwdriver fully counter
clock wise to the minimum position. Do not apply
any pressure while turning as this might break
the control unit. Adjust your radio volume level
to maximum volume. now turn the level control
on the amplifier clockwise towards the Maximum
marking until audible distortion occurs. When you
begin to hear any distortion in the sound, back
down one notch and your amp is set.
It is helpful to have a second person to help you
set the gain.
When setting up a multi-amp system, set each
amplifier’s gain separately. Start off with the bass
amplifier, then adjust the highs amplifier’s level
control to match.
once you are satisfied with the level control
settings, use any equalizer controls to adjust the
system tonal level for personal preference. Keep
in mind that after equalizing, you may have to go
back and reset the amplifiers level controls.
The level control of any car audio amplifier
should not be mistaken for a volume control. It
is a sophisticated device designed to match the
output level of your source unit to the input level
of the amplifier. Do not adjust the amplifier gain
to maximum unless your input level requires it.
If your unit has been professionally installed
please do not change the gain settings by the
installer, he is the professional!
Your system can also be extremely sensitive to
noise when the level is set to maximum and does
not match your input signal. the gain adjustments
need to be made only once when first setting up
the system.
