WARNING
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.

INSTALLATION GUIDELINES
1. Please read this owner’s manual
carefully before installing this ampli-
fier.
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’s power
wire. Remember, the amplifier can
only deliver its rated output when it
is not current limited by the power
and ground supply wires.
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 spot
welded.
8. This amplifier is designed to drive a
speaker load that measures from 2-
8 ohms (sub ch 1-4 ohms). Keep in
mind that heat is the long-term
enemy of automotive electronics
7. Always fuse your power connection
within eight to ten inches of the
6
© 2003 Directed Electronics, Inc
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.
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.
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.

CROSSOVER SETTINGS AND GAIN ADJUSTMENT
Your Directed Audio power amplifier 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
selection 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.
„ For systems using the Remote Sub Level Adjustment, increase the subwoofer gain
on the amplifier by 25% and set the Remote Sub Level knob to the center position
after making all system gain and filter adjustments. This will give the Remote Sub
Level Control a wider range of adjustment to the subwoofer output.
„ 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!
