MOUNTING AND WIRING
MOUNTING THE AMPLIFIER
The DAK Series amplifers feature four mounting
tabs located at the amplifier four corners. Mount
the amplifer into position using the supplied
screws and grommets securing it tight.
be careful to allow enough clearance around the
amplifier for air movement,
avoid installing the amplifier in a position where
it may in contact with rain, water or other liquids,
keep your installation clear of any parts of the
vehicle that can either endager your safety or the
safe operation of the vehicle,
don't drill near the fuel tanks and electrical
components.
Before you begin with your installation, disconnect
the NEGATIVE (-) terminal from your car battery.
This safety precaution will avoid possible short
circuits while wiring your amplifier. Dragster
amplifiers operate on 12-volt negative ground
systems only.
It is recommended that you layout your sound
system design on paper first. This will help you
during the installation so that you will have a
wiring flow chart and not miss-wire any of your
components.Mount the amplifier in the trunk
or hatch area of your vehicle. Never install an
amplifier in the engine compartment or on the
fire wall. Please be sure to leave breathing room
around the amplifier heat sink so that you can
dissipate the heat it produces efficiently. When
mounting the amplifier on the truck floor, be sure
to watch for your gas tank, gas lines and electrical
lines. Do not drill or mount any screws where they
might penetrate the gas trunk of your car.
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 Ground.
We recommend that you use the Dragster DP
KIT.4 or DP KIT.8 amplifier connection kits, which
contains all the cabling and accessories necessary
for a good, reliable installation.
FUSES
The DAK Series amplifiers are supplied with built-
in fuses, never replace the fuse that the amp came
with, with one of larger value.
We suggest you construct a RED wiring hardness
with 2 additional 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+.
WIRING POWER/GROUND CABLES
The wirehardness should be made of red primary
cable of at least 4 gauge for all DAK Series
amplifiers. The hardness should terminate in a
large ring terminal 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 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 insulator
blocking a good ground connection.
WARNING: Over the years we have experience
of amplifiers with melted power/groud
terminals. The cause of this is a bad ground
connection. When there is a lack of good
ground, heat builts 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 the amplifier
connection after having played the amp 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.
REMOTE TURN ON CONNECTION
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 have any
turn on leads, you can wire the remote terminal to
an accessory lead, which turns on, with your cars
ignition.

SIGNAL CONNECTION

AUDIO PREAMP INPUT
The DAK Series amplifiers feature RCA pre amp
inputs. 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
reduce and eliminate unwanted electrical noise to
your system. 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.
LINE OUTPUT
The DAK Series amplifiers Mono block (DAK 1001,
1501) and 2 channel (DAK 802, 1202) feature RCA
pre amp line output for feeding of a full range
signal to a secondary full range amplifier in a
multi-amp system.
REMOTE TURN ON CONNECTION
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 have any
turn on leads, you can wire the remote terminal
to an accessoiry lead, which turn on, with your car
ignition.
4 CHANNEL AMP WITH 2 CHANNEL INPUT
(DAK 804, 1204)
If your head unit has only one pair of Left and
Right RCA output jacks, plug them into RCA input
jacks 1 and 2 of the amplifier. The amplifier
preamp circuit will automatically mix the signals to
channels 3 and 4 thereby preserving your Left and
Right Balance control but with no Fader control
Front to Rear.
Check scheme #2 at page 26
4 CHANNEL AMP WITH 4 CHANNEL INPUT
(DAK 804, 1204)
If your head unit has two pairs of RCA output
jacks, input Front Left and Front Right channels 1
and 2. Then attach the Rear pre-out to channels
3 and 4. The pre-amp circuitry will not mix any
signal thereby preserving full left to right balance
and front to rear fader control.
Should your head unit have an additional
subwoofer RCA output it would need to be
attached to a separate subwoofer amplifier.
When configuring a four channel amplifier to a
three channel system, you can use an RCA "Y"
adaptor to send the subwoofer pre amp signal to
