Congratulations and thank you for purchasing the new PPI woofers. At
PPI we are proud to introduce this exciting line of outstanding sounding
products. We have spent the past 15 years developing the most innovative
and state of the art products on the market. The PPI products continue
this design and construction philosophy by offering superior features and
performance greater than that of our competition.
Included in this manual are a number of different enclosure suggestions.
By no means are these the only enclosures to use, but they are a great starting point. To determine the correct enclosure for your needs many factors
must be addressed (amount of power, vehicle, placement, crossovers, etc.)
Therefore, as always, PPI recommends that your subwoofer be installed by
an Authorized PPI Dealer.
CAUTION! The extended use of a high powered audio system may result
in hearing loss or damage. While PPI systems are capable of “Concert
Level” volumes, they are also designed for you to enjoy all of the creative
expressions made by musicians at more reasonable levels. Please stay
seated while driving and observe all local sound ordinances.

displacement if used). It may be necessary to angle the port to fit your
design. To calculate the volume of the port: Radius Sq. x 3.14 x port length.
