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 vehi­cles. 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 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
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 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 1
to 4 ohms. Keep in mind that heat
is the long-term enemy of automo­tive electronics and the lower your

7

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 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.

outputs from head units or signal
processors at voltages between
150mV and 8 volts.

Sync Out - This RCA jack sends a
Synced or in-phase gain matched
output signal to a slave amplifier
when connected in the Parallel
Synced Gain combination. It is a
Synced output when the
slave/master switch is in the
MASTER position only.

Slave In - This RCA jack accepts
input from a master amplifier. It is
for use in the Parallel Synced Gain
and External Synced Bridged combi­nations. It is a slave input when the
slave/master control switch is in
the SLAVE position only.

DO NOT connect a level control knob from other
manufacturers to the Remote Sub Level Control of
any Viper amplifier. Even though the connectors fit
properly, the control knob and connector pin posi­tions may be different and the amplifier will be
damaged.
