POWERBASS AUTOSOUND L2 FULL RANGE FEATURES
Advanced Injection Molded Cone: An injection molded PP cone with carbon fiber was developed for better
bass performance while minimizing distortion. This ultra lightweight cone is resistant to elements of the
environment while giving the listener impeccable listening experience over the factory speakers.
Aluminum Hard Dome Tweeter: Ferrofluid enhanced aluminum dome tweeters deliver sharp clarity and crisp
treble reproduction. The low profile design makes upgrading factory speakers a simple non-evasive task. (The
L2-693 and L2-700 do not use aluminum tweeters).
Wave Guide Tweeter Lens: A specially engineered tweeter wave guide provides smooth and uniform
response giving more high frequency sound propagation.
High Power 2-ohm Prime Voice Coil: These highly efficient 2-ohm coils were designed for greater efficiency
and are compatible with most premium factory sound systems to make your vehicle sound better than ever.
High Damping Butyl Rubber Surround: Butyl rubber was chosen to ensure linear travel throughout the entire
frequency range resulting in more bass output and higher efficiency while reducing distortion.
Non-resonant Basket Treatment: Each steel speaker basket has been treated with a proprietary resonant
damping material making the speaker platform acoustically “dead”.
Additional Features: Acoustically transparent speaker grills*, professional mounting hardware and splice-in speaker
wiring harnesses add further value to your speaker investment.

Before beginning your installation, thoroughly read this guide and keep it as a reference. It will
give you tips on proper placement, wiring, and installation as well as how to obtain the best sound
from the PowerBass speakers you have selected.
INSTALLATION EXPERIENCE
Installation of PowerBass Autosound Speakers requires experience with a variety of mechanical and electrical
procedures. This manual only provides general installation and operation instructions. If you have any reserva-
tions about your installation skills or lack of the proper tools, please contact your local PowerBass Autosound
dealer for assistance.
TIPS TO GET THE MOST OUT OF YOUR POWERBASS SYSTEM
Your PowerBass Autosound speakers have been meticulous engineered and designed to handle high power
musical reproduction. Despite their rugged construction, it is possible to damage your speaker if they are
improperly used. In general, you will hear distortion as a so-called warning before any damage occurs. If you
hear distortion in your system, immediately reduce the musical level to the point where the sound retains its
clarity.
1. Be sure you supply the speakers with enough unclipped amplifier power to drive them properly. (More
damage can be done to a speaker by under-powering and clipping your amplifier than any other
way!)
2. Where possible, a separate amplifier just for your speaker should be used with an electronic crossover to
set the frequency range. One amplifier with passive crossovers will work (Tri-Way Setup), but the system
will do more with less stress on the amplifier by using two amps.
3. To avoid any possible sound cancellation from the front of the speaker to that of the rear of the speaker,
cut a panel of Masonite or MDF to firmly mount the speaker if the vehicle’s original cutout is too big.
4. When connecting speaker wires from the amplifier or head unit to that of the speaker itself, pay attention
to the polarity of the connection. This will insure optimum sound reproduction and performance.
5. For maximum dynamic performance use weather stripping to insure a tight seal.
6. Do not mount any speakers or external crossovers where they will get wet.
7. Remember the Golden Rule “Measure twice…cut once.”

ILLUSTRATION OF REAR DECK MOUNT INSTALLATION
INSTALLATION PROCEDURES
• Since these speakers utilize a unique low profile tweeter housing that has minimal tweeter protrusion,
original factory mounting cutouts can still be used with the factory grills in many cases.
• These PowerBass Autosound speakers can be used above or below the mounting hole. Typically, your
vehicle factory’s speaker cutouts will accommodate these new speakers without any modifications.
When the speaker has been correctly installed, there should be no air leaks between the front and back
of the speaker.
• For door installations, check the clearance of the window and roll-up mechanisms throughout the entire
range of the window’s travel to make sure that all obstacles clear the speaker structure.
• Check the available mounting depth before installing the speaker. Use care when removing factory grills,
door panels and factory speakers.
