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.

SOUND QUALITY
Obtaining the highest quality sound
reproduction in the mobile environment
requires installation techniques and
knowledge of vehicle interiors that go
far beyond simple replacement of stock
speakers. Speaker location, orientation,
phasing, and the vehicles interior mate-
rials are important considerations when
designing and installing an auto sound
system.
To achieve the best sound quality
possible from your Viper Audio loud-
speakers, Directed recommends the
installation be performed by an MECP
certified technician.
INSTALLATION PRECAUTIONS
The Viper 550.2/650.2 neodymium
separates are designed for installation
into factory speaker locations, custom
mounting enclosures or any flat mounting
surface inside the vehicle with sufficient
rear clearance. The following precautions
and instructions cover the basic and most
common types of installation.
distortion or shorting of the speaker
leads to the chassis ground. Over-
sized holes will not allow the
mounting screws to make sufficient
contact with the panel, allowing the
speaker to become loose.
„ Always protect the wires when
routing by avoiding sharp metal
edges, moving parts such as heater
or vent controls, clutch pedals, brake
pedals, steering columns, and power
window motors and gears.
„ Check behind panels for clearance of
metal brackets, hoses, and wire
harnesses before making any cuts.
„ When mounting speakers into doors,
roll the window up and down to
check clearance of the glass and
window regulator.
„ When routing wires through metal
panels and doorjambs always use
vinyl tubing and grommets for
protection and a professional-looking
installation.
„ Make sure the mounting holes are
the correct size for the speaker.
Undersized holes can cause speaker

1. Place the cutout template against
the mounting surface in the desired
location for the woofer.
6. Install the screw speed clips if not
installing into a metal panel.

4-7/8" hole
„ The 650.2 woofer requires a
5-3/4" hole.
3. Remove the cutout template and
carefully cut the speaker hole to the
proper size. If there is a pre-existing
hole that is undersize, mark it and
cut it to the proper size. If the hole is
oversize, it is recommended that a
spacer be built to compensate.
9. Place several pieces of the butyl
compound on the edge of the
speaker grill, then press the grill into
the speaker-mounting flange.
NOTE:
A supply of butyl compound is included and can
be used to attach the speaker grill as well as
prevent rattles.
4. Pre-drill the holes for the mounting
screws using a 1/8" drill bit.

proper size hole. Cut out the hole.
5. With the tweeter assembled, route
the wires through the hole and the
pressure ring and slip the pressure
ring over the tweeter assembly.
Flush Mounting into
Removed Panels
1. Determine the tweeter mounting
location, then route the wires from
the crossover to the tweeter location.
6. Align the tweeter so the Viper logo
faces the desired direction then push
the pressure ring on to the rear of
the tweeter assembly until the
tweeter is snugly mounted to the
panel.
2. Mark the center point of the tweeter
location.
3. If using a hole saw, first drill a pilot
hole, then cut out the hole using a
standard 2-1/8" hole saw.
7. Connect the speaker wires observing
the correct polarity and re-assemble
the panel.
4. If not using a hole saw, use either
the cardboard packaging for the
tweeters or the surface mount trim

7. Press the X-bracket portion of the
assembly through the hole until its
legs spring open.
3. If using a hole saw, first drill a pilot
hole, then cut out the hole using a
standard 2-1/8" hole saw.
8. Screw the bolt in until the tweeter
housing is firmly mounted to the
panel. (Make sure the arrow at the
rear of the tweeter housing is
pointing in the desired direction.)
4. If not using a hole saw, use either
the cardboard packaging for the
tweeters or the surface mount trim
ring as a template to mark the
proper size hole. Cut out the hole.
9. Insert the tweeter into the housing
and attach trim ring. (Refer to the
trim ring information at the end of
this section.)

Tweeter Surface Mounting
5. After removing the surface mount
tweeter assembly trim ring, route
the tweeter wires through the larger
hole in the housing and connect to
the speaker wires from the
crossover. (See Figure 4.)
1. Determine the tweeter mounting
location, then route the wires from
the crossover to the tweeter loca-
tion.
2. Place the surface mount housing
against the panel and mark the two
holes at the rear of the housing.
6. Insert the excess speaker wire into
the hole and position the housing so
the housing will not pinch the wires
after final mounting.
3. Drill the smaller center hole using a
1/8" drill bit. This is the mounting
screw hole.
7. Attach the housing using the
supplied screws of the correct length
for a solid mount.
4. Drill the larger off-center hole using a
3/8" drill bit, insert a grommet and
route the speaker wire from the
crossover through the grommet.
8. Insert the tweeter into the housing
and attach the trim ring.

CROSSOVER INSTALLATION
Input Switch
The input switch tells the crossover what
type of amplifier system is being used.
Review the Installation Precautions
section of this guide before proceeding.
Crossover Adjustment and
Wiring Connections
If a single amplifier channel will power
both the tweeter and the woofer, follow
the Single Amplifier Input instructions.
(See Figure 5.)
This Viper crossover has the ability to
work in car audio systems from basic
single amplifier systems to the most
sophisticated multiple amplifier systems
with signal processors and amplifier chan-
nels dedicated to each speaker.
If an amplifier channel will power the
tweeter and another channel will power
the woofer, follow the Dual Amplifier
Input instructions. (See Figure 6.)
Control Switches
Attenuation Switch
The control switches can be accessed
under the removable elliptical cover next
to the input connector. Pry up the cover
to make crossover adjustments.
The tweeter attenuation switch can
adjust the tweeters from +3 dB to -6 dB
to compensate for vehicle interior and
mounting location. It is used to brighten
or soften the tweeter response according
to listener's preference. (See Figure 5.)
