Remove the trim panels and inspect the installation locations before you cut and drill the holes
required to mount the woofer. Removing the panel will also make it much easier to route
wiring inside the door. Look for original equipment speaker installation cutouts that can often
be used to install the woofers with little or no modifications. Use the template supplied to help
you locate and mark the holes needed to install the speakers.
When installing the 336PX woofer in a door be sure it will not interfere with the window
lowering mechanism. Be sure that the speaker wires clear all moving parts inside the door.
For each woofer you will need to cut one large hole and drill six small holes around the
circumference. If the mounting surface is covered by carpet or fabric, use a knife or razor to
cut the material away from the holes and cutting path. This prevents material or fibers from
becoming tangled in the drill bit or cutting blade.
We recommend that you use #8 or 4mm sheet metal or machine screws, depending on the
composition of the mounting surface. These are not included.
Clean the work areas of all filings and shavings with a vacuum cleaner before you proceed
with woofer mounting.
Route the speaker wire from the woofer installation locations to the crossovers. Pull the wire
through the installation hole and attach the wire to the terminals on the speakers. The speaker
terminals will accept up to #12AWG wire. Connect the positive wire to the positive (+)
terminal indicated by the red ring. See the information in the Polarity section of this manual
and the wiring diagrams. Push the wire back into the area behind the installation location. Be
sure it will not interfere with the speaker.
