JL Audio TR650-CSi - Manual (Page 4)

FLUSH MOUNT INSTALLATION:
1) Remove the vehicle panel and check to
ensure that there is at least 3/4 inch (19mm)
clearance behind the panel for the tweeter’s
magnet structure.
2) Carefully cut a 1 9/16-inch (40 mm) diameter
hole in the vehicle panel.This will achieve a snug fit
and allow the tweeter flange to conceal the cut line.
3) Insert the tweeter from the front of the panel
(do not attach the spring clip at this time).
4) Attach the spring clip from behind the panel
using the supplied 1/4 inch (6 mm) machine screw.
5) Tighten the screw by hand until the tweeter is
tight on the panel. Do not overtighten.
6) Connect the tweeter’s wires to the supplied
harness with the in-line high-pass filter.
7) Re-install the vehicle panel, taking care to
route the new wiring so as not to interfere with
any vehicle mechanisms (window mechanisms,
for example).

TWEETER INSTALLATION:
The dome tweeters supplied with your
TR650-CSi system have been designed for surface
or flush mounting. Before choosing a method,
carefully inspect the desired mounting location to
determine which method will work best.
1) Flush Mounting will yield a custom-installed
appearance, but will require at least 3/4-inch
(19 mm) of clearance behind the mounting
surface of the tweeter.
2) Surface Mounting, using the supplied surface
mount kit and hardware requires the drilling of
three holes (one for the wires and two for the
mounting screws).This application is useful when
mounting the tweeters to a panel that has
insufficient clearance behind it for the tweeter’s
magnet structure.
TWEETER CONNECTIONS:
Run the supplied wiring harness with the in-line
filter from the extra tabs on the component
woofer to the tweeter mounting location.Then
connect this harness to the wires attached to the
tweeters, observing correct polarity. In some
cases, it may be easier to run the tweeter wires
directly to the amplifier output, instead of
connecting them to the component woofer
terminals.This is functionally identical to the first
method (it is a simple, parallel connection).
See Wiring Diagram on page 2 for details.
SURFACE MOUNT INSTALLATION:
1) Remove the vehicle panel and check to
ensure that the mounting screws will have
adequate clearance.
2) Place the surface-mount fixture on the vehicle
panel at the desired mounting location and mark
the location of the two mounting screw holes and
the approximate center of one of the two
rectangular cutouts (for the wires).
3) Using a 1/16-inch (1.5 mm) drill bit, drill a hole
through the panel at the two screw locations.
4) Using a 1/2-inch (12 mm) drill bit, drill the
hole for the tweeter’s wires at the location you
marked in step 2.
5) Screw the surface mount fixture to the vehicle
panel using the supplied #6 sheet metal screws
(hand-tighten).
6) Feed the tweeter wires through the
rectangular hole in the mounting fixture and the
1/2-inch hole you drilled in the panel.Then, snap the
tweeter into the surface mount fixture.
7) Connect the tweeter’s wires to the supplied
harness with the in-line high-pass filter.
8) Re-install the vehicle panel, taking care to
route the new wiring so as not to interfere with any
vehicle mechanisms (window mechanisms,
for example).
