INSTALLATION GUIDELINES
High-powered car audio
systems may produce sound
pressure levels that exceed the
threshold at which hearing loss may
result.
They may also impair a driver’s ability to
hear traffic sounds or emergency vehi-
cles. Use common sense and practice
safe listening habits when listening to or
adjusting your audio system.
WARNING
FEATURES
High-speed MOSFET power supplies
Complimentary bipolar transistor
outputs
Either mono only (XA-8001, XA-
5001) or stereo/mono (XA6002).
The XA-6004 can have rear bridged

1. Please read this owner’s manual
carefully before installing this ampli-
fier.
2. Disconnect the battery ground
terminal prior to making any elec-
trical connections.
3. Check for any hazards or obstruc-
tions such as gas tanks, fuel or
brake lines, and wiring harnesses
before mounting the amplifier.
4. Pick a mounting location that will
provide adequate access and venti-
lation and protect the amplifier
from heat, moisture, and dirt.
5. Avoid sharp metal areas when
routing cables to the amplifier, and
run RCA cables away from the
power cables and other potentially
noisy car harnesses.

6. The amplifier should be grounded
with a short, heavy gauge wire
connected directly to the car at a
bare metal surface, preferably
scraped body sheet metal. Do not
use factory ground locations, seat
bolts, or brackets that are
spotwelded.
7. Always fuse your power connection
within 8 to 10 inches of the battery
terminal. Use a fuse or circuit
breaker rated slightly more than the
on-board fuse(s) of the
amplifier(s). The gauge of power
wire used should take into account
the total current draw of the
system, and the length of wire
used. IASCA and other auto sound
competition organizations have
charts available for this; you can
also find a chart in the MECP study
guide. Minimum wire gauge recom-
mendations for the individual ampli-
fiers are listed on the specification
page. Always use the same gauge
wire for the amplifier ground that
you use for the power wire. Be sure
to examine the battery ground
cable of the vehicle, and if neces-
sary, upgrade it by adding an addi-
tional ground wire that is the same
gauge as the amplifier power wire.
Remember, the amplifier can only
deliver its rated output when it is
not current limited by the power
and ground supply wires.
8. This amplifier is designed to drive a
speaker load that measures from 2
to 4 ohms. Keep in mind that heat
is the long-term enemy of automo-
tive electronics and the lower your
speaker load, the more heat is
generated. For low impedance
speaker applications or restricted
ventilation installations, an external
cooling fan may be advisable.
9. Battery and ground connections to
the vehicle should be made with
crimped ring terminals of the appro-
priate size (surface area is what
counts); soldering the terminals
after crimping is also recom-
mended.
10. Due to the high-frequency MOSFET
switching power supply, filtering the
power cable is not generally
required (remember that the amp
can’t deliver full output if the power
supply is restricted). Proper
grounding of the signal source is
mandatory for the amplifier to
reach its performance peak. If the
RCA inputs are not grounded
adequately via the signal source,
electrical noise from the vehicle
may be picked up in the system.

10. SSppeeaakkeerrCCoonnnneeccttiioonnss- Note that the
two speakers & four speakers have
been connected to the four terminal
following the (+) and (-) graphic.
Your speaker terminal may be
marked (+) and (-) or there may
be red dot by one terminal which
means the same as (+).
Connecting the speakers in this
manner assures that the two
speaker cones will move in and out
together according to the original
recording. If one of the two
speakers is reversed, stereo
imaging and bass response will be
degraded.
Refer to the specifications for the
wire size to be used with your
amplifier.
11. AATTCCFFuusseess- protects the amplifier
from over current situations. See
specification for fuse size for your
amplifier. NNoottee::The XA-3002 has
only one fuse.
12. ((++))1122VVoollttPPoowweerr- Connect this
terminal through a FUSE or CIRCUIT
BREAKER to the positive terminal of
the vehicle battery or the positive
terminal of an isolated audio
system battery. Refer to the specifi-
cations for the wire size to be used
with your amplifier.
WWAARRNNIINNGG::Always protect this power wire by installing a fuse
or circuit breaker of the appropriate size within
12 inches of the battery terminal connection.
RReemmootteeTTuurrnnOOnn- This terminal
turns on the amplifier when (+) 12
volt is applied to it. Connect it to
the remote turn on lead of the head
unit or signal source. If a (+) 12
volt remote turn lead is not avail-
able, a Remote Power Adapter
(P/N #55000) can be used to
supply a remote turn on signal. DO
NOT connect this terminal to
constant (+) 12 volt.
GGrroouunndd--Connect this terminal
directly to the sheet metal chassis
of the vehicle using the shortest
wire necessary to make this
connection. Always use wire of the
same gauge or larger than the (+)
12 volt power wire. The chassis
connection point should be scraped
free of paint and dirt. Use only
quality crimped and/or soldered
connectors at both ends of this
wire. DO NOT connect this terminal
directly to the vehicle battery
ground terminal or any other
factory ground points.

The XA-5001, and XA-8001 amplifiers offer two positive and two negative output termi-

the speaker connectors are paralleled internally. Each amplifier is stable to 2 ohms.
NNOOTTEE!!The XA-5001 and XA-8001 are not designed to work in a bridged or strapped
configuration. Attempting to apply these configurations will damage the amplifier and

CROSSOVER SETTINGS AND GAIN ADJUSTMENT
Your Xtreme Series power amplifier by Directed Audio needs to be adjusted carefully to
achieve maximum performance. These are some guidelines to follow when fine-tuning
the amplifier.
For full-range and simultaneous stereo/mono bass applications, the crossover selec-
tion switch should be set to FLAT. If the amplifier is driving your subwoofers, set the
switch to LPF, and for mid-bass/midrange output, set to HPF.
The crossover frequency control needs to be adjusted to suit your particular system.
For subwoofer applications, try to keep the setting low enough to prevent the
image smearing (you should not be able to hear male voices from the subwoofer)
but not so low as to create a gap between the subwoofer and the mid-
bass/midrange speakers. For mid-bass/midrange settings, try to keep the setting
low enough to keep your sound stage in front of you, without overdriving the
speaker. It will be to your advantage to spend some extra time with this adjust-
ment, listening to familiar music or system set-up discs to achieve the kind of
musical reproduction that you prefer.
The gain adjustment allows you to set proper signal match for clean, quiet ampli-
fier operation. For full-range and simultaneous stereo/mono bass applications,
start by playing some music you are familiar with. With the gain adjustment on
the amplifier in the middle of its rotation, bring up the volume on your head unit
to the 3/4 volume setting or until you start to hear distortion or clipping. If you
hear distortion before you reach the 3/4 volume setting of your head unit, reduce
the gain setting on the amplifier and start to raise the head unit volume again.
When you can listen to the music at or slightly above 3/4 on your head unit
without audible distortion, slowly raise the gain of the amplifier until distortion is
heard, then back off the gain until the distortion is not audible. This setting will
allow you to reach full output with all but the quietest of source material, while
avoiding excessive noise in the system.
The same procedure should be used for adjusting the amplifier when the on-board
crossover is set to LPF or HPF, but you will also have to take into consideration the
effect that gain adjustment has on system frequency response and imaging.
Again, plan on spending some time with music that you know, getting the gain
and crossover settings the way you like. Test discs and analyzers may help with this
process, but in the end it's your ears that count - listen to the music!
