Owner’s Manual/Installation Guide – 5
PRECAUTIONS AND NOTES
• The Kappa 202a has five levels of circuit protection
that monitor the amplifier and will shut it down if the
electrical system voltage drops below 10 Vdc or
exceeds 15.5 Vdc, temperatures are above 194° F (90°
C), short circuits occur, or current draw exceeds
product specifications. For best performance, check
the intended mounting site to make sure the
operating environment does not create conditions that
will trigger circuit protection.
• Prior to installation, turn off all audio systems and
other electrical devices. Also disconnect the (–)
negative lead from the vehicle’s battery.
• At the installation site, locate and make a note of all
fuel lines, hydraulic brake lines, and electrical wiring.
Use extreme caution when cutting or drilling in and
around these areas.
• Use the amplifier as a mounting template to mark
locations for the mounting holes.
• Check clearances on both sides of a planned mounting
surface before drilling any holes or installing any
screws. Remember that mounting screws can extend
up to an inch behind the surface.
• Always wear protective eyewear when using tools.
• The Kappa 202a uses gold-plated, industrial-grade
Weco
®
plug-in connectors for power and speaker
wiring. Because of precision tolerances, do not insert
the connectors into the amplifier without pre-wiring
them first. Once the wires are fastened in each shell,
they provide additional gripping area for easy
connector removal.
• When routing cables, keep input signal cables away
from power cables and output speaker wires, as
shown in Figure 6 (below).
• When making connections, make sure that each
connection is clean and properly secured. Observe the
polarity markings on the rear panel. Refer to the
application drawings (Figures 1 through 3 on page 3)
to set up the amplifier for operation in stereo, bridged-
mono, bi-amp, or tri-mode configurations.
• If the amplifier’s fuse needs replacement, use only
the same rating and type as a replacement. Do not
substitute another kind.
