Planning the installation
The modular configuration of the 336PX makes it possible to mount the individual units in a
variety of locations. However, due to the nature of the construction of the 336PX frames, high
precision is required when cutting the mounting holes for installation of the woofer. Likewise
the tweeter is designed for flush mounting only. You will need access to the area immediately
behind the tweeter mounting panel in order to tighten the locking ring.
For the best imaging and most coherent sound, the output from the woofer and tweeter of
each channel should reach the listener at the same time and from the same direction. The best
results will generally be achieved when the woofer and tweeter are adjacent to each other.
Many installations however may dictate that the two units are separated. If they are mounted
too far apart, the sound they produce may lose coherence.
A woofer mounted on the front door, for example, could have its corresponding tweeter
mounted on the dashboard near the door. It would be inappropriate, however, to mount the
tweeter on the dashboard or front door with the woofer on the rear deck.
The 336PX bass / midrange speakers produce maximum undistorted bass output when
mounted on a rigid surface and in an enclosure which is acoustically isolated from the
passenger compartment. The front doors are often the best locations for the woofers. In some
cases you may be able to mount the woofers in the front kick panels if the areas behind the
panels are reasonably large. In other cases, it may be possible to use existing openings
provided by the auto manufacturer for factory options. Thin panels or shelves must be
reinforced with fiberboard or sheet metal. Steps should also be taken to eliminate air leaks in
and around the mounting surface.
Use the supplied templates when planning the installation. Be sure you have enough clearance
behind the mounting panel. When installing speakers on a rear deck, watch out for trunk lid
hinges and springs. If you are mounting speakers in doors, be sure they will not interfere with
the window operating mechanism. Check the intended installation location with the window
down as well as up.
Label the free ends of all wires before routing so they can be quickly and accurately identified.
It is especially important to avoid reversing the woofer and the tweeter connections.
Amplifier requirements
The 336PX will operate well on as little as 20Watts RMS per channel to achieve reasonable
volume levels in a moving vehicle without clipping the amplifier. We recommend a maximum
of 150 watts so as not to exceed the thermal or mechanical limitations of the speaker system.
The use of a low powered amplifier to try to attain very high output levels can lead to
overdriving the amplifier. This will generate high distortion levels which can easily damage the
loudspeakers, even if the amplifier’s rated power is far below the rated power of the
loudspeaker.
As a rule, do not turn the volume up past the point where you hear distortion from either an
overstressed speaker or amplifier. For the best performance and reliability, select an amplifier
