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.
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 perfor-
mance. 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 connec-
tion.
