inaccessible. Give some thought to the electrical connec-
tions. You may be able to fish the tweeter signal wire to the
crossover network location after installation of the tweeter
assembly. You may need to fish a signal wire from the
crossover network location to, and then through, the
mounting hole and the rear cup before the cup is inserted
through the mounting hole. You can then connect the sig-
nal wire to the tweeter wire.
Once you have decided the signal wire connections, pass
one supplied #6 x 1 1/2” long screw through the slotted
hole in the front cup and turn a couple of threads into the
rear cup. This will allow enough mobility of the two cups to
allow the rear cup to be inserted through the mounting
hole. The two cups can be screwed together using the long
screw and a second #6 x 3/4" through the remaining hole
to pinch the mounting surface between them.
tweeter mounting
Route speaker wire from the crossover locations to the
tweeter locations. Pull the wire through the wire hole and
attach crossover wires to the wires from the tweeters. Con -
nect the positive wire to the positive (+) terminal on the
tweeter, which is marked with a red wire. See the informa-
tion in the speaker wiring section of this manual and the
wiring diagrams. Push the wire back into the area behind
the installation location and be sure it will not interfere with
the speaker or with anything behind the mounting panel.
To attach the tweeter to the surface or flush mount cup,
align the tabs in the mounting cup with the relieved areas in
the tweeter module. The wires should line up just to the
right side of where the a/d/s/ nameplate is located on the
sufrace mount cup.
Note: once the surface mount cup is attached to the mount-
ing surface, there is only one position in which the tweeter
can be properly seated into the surface mount cup.
Gently push the tweeter into the mounting cup, take up the
slack in the wire, and twist clockwise until it moves no fur-
ther. Do not force the unit if it does not turn freely. If the
tweeter is not lined up properly with the tabs or the wire is
interfering, the tweeter will not fully seat into the cup.
To remove the tweeter, simply turn it counter-clockwise,
and pull the tweeter away from the cup.
6-series speaker system is supplied with three different tweeter mounting options. Surface, flush
angled flush mount. After you have decided which option is best suited to your installation, refer
he following sections for specific details on mounting the tweeter.

preparation of the mounting surface for the tweeter involves drilling three holes. Two holes are for
mounting screws. Their centers must be spaced 15/16” / 24mm apart. Use a 1/8" / 3mm drill bit

e: the orientation of the three holes determines the installed position of the tweeter.

e: place enough washers over the protruding screws on the back of the front cup so that their com-
d thickness is somewhat less than the thickness of the mounting surface. This will insure adequate
nching” of the mounting cups without danger of breaking the rear cup.
