INSTALLATION GUIDELINES

1. Please read this owner’s manual
carefully before installing this ampli­fier.

2. Disconnect the battery ground
terminal prior to making any elec­trical connections.

3. Check for any hazards or obstruc­tions 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 venti­lation 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
fuse(s) of the amplifier. 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 recom­mendations for the individual ampli­fiers 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 neces­sary, upgrade it by adding an addi­tional 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.

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 automo­tive electronics and the lower your
speaker load, the more heat is

7

© 2002 Directed Electronics, Inc

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 appro­priate size (surface area is what
counts); soldering the terminals
after crimping is also recom­mended.

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.

Power and speaker wire connections on
Viper Audio power amplifiers are
performed with the use of specially
designed connectors that allow for ease
of wire termination and installation
convenience.

Poor connections are a common cause
of poor sound quality or amplifier perfor­mance. Making proper wire connections
is paramount to a reliable, quality sound
system.

Please follow these recommendations to
ensure a problem free installation:

1. Always use the proper gauge wire
for the connector.

2. Cut wires to the minimum length
necessary.

3. Trim the wire ends so bare wire
does not protrude from the
connector after termination.

4. Always tighten the connector
screws firmly at least twice, once
during installation and once more
before returning the car to the
customer.

CCAAUUTTIIOONN::

Over tightening the screws can cause them to
strip, creating loose connections. Tighten the
screws twice firmly for a permanent, solid
connection.

The Viper d2500.1 subwoofer amplifier
has the capability of connecting two or
more d2500.1 amplifiers in a
master/slave combination for increased
power with accurate level matching. It is
called the Parallel Synced Gain combina­tion.

WWAARRNNIINNGG::

DO NOT attempt to combine amplifiers of different
power ratings. This amplifier combination works
correctly only if the Master and Slave amplifiers are
identical models.

Parallel Synced Gain

In this master/slave combination the
master amplifier pre-amp controls remain
active and the slave amplifier pre-amp is
bypassed. This allows the master ampli­fier to control gain, filter, and sub-level
on all amplifiers.

This combination allows the amplifiers to
drive their own separate subwoofer(s)
while being synced together via an in-

phase audio pre-amp signal from the
master amplifier. Wiring connections to
the amplifier subwoofer outputs in this
combination should be standard in-phase
configurations, creating a parallel
speaker connection. (Refer to

Parallel

Synced Gain

section of this guide for
amplifier and speaker connection
diagrams.)

NNOOTTEE::

One master amplifier can control up to three slave
amplifiers in this combination. Multiple identical
master/slave combinations can be added to any
given system.

Combined Amplifiers Gain
and Filter Settings

Set the Subsonic, EQ, and other filter
settings on the master amplifier to the
positions that achieve the best sound
quality. Adjustment guidelines are
discussed in the

Crossover and Gain

Adjustment

section of this guide.

COMBINING AMPLIFIERS

The Viper d2500.1 subwoofer ampli­fiers can also be used in multiples of the
Parallel Synced Gain combination
allowing for unlimited expansion to a
systems subwoofer section. To use
multiples of the Parallel Synced Gain
combination the following directions
must be adhered to for best results.



AAuuddiioo ssiiggnnaall

- Divide the head unit
or processor audio signal to the
master amplifier by using RCA Y
adapters. Be sure to divide them an
even number of times to ensure the
input level at each master amplifier
is matched.



RReemmoottee SSuubb LLeevveell CCoonnttrrooll

- The
Remote Sub Level Control cable can
be divided several times to connect
to each master amplifier. This can

be accomplished by using one or
more Directed Remote Sub Level
cable splitters. Standard single-to­double phone line splitters and
accessories from a local electronics
store can also be used.

For systems with more than two
master/slave combinations, use
multiple single-to-double splitters.
Do not use phone splitters that
divide the signal more than once
per splitter or splitters designed for
multiple uses.

CROSSOVER SETTINGS AND GAIN ADJUSTMENT

18

© 2002 Directed Electronics, Inc

Your Viper Audio power amplifier needs to be adjusted carefully to achieve maximum
performance. These are some guidelines to follow when fine-tuning the amplifier.

 Because this amplifier is only designed for subwoofer applications, the low-pass

crossover is active at all times. The crossover point is adjustable to allow more
precise system operation.

 Try and keep the setting low enough to prevent 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. It will be to your
advantage to spend some extra time with this adjustment, 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. 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.

 You should take into consideration the effect that gain adjustment has on system

frequency response and staging. 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!
