B. IMPORTANT!!! Refer to the driver documentation to determine
whether to use a sealed or ported enclosure. If the manufacturer
recommends a sealed enclosure continue to step C. If the
manufacturer recommends a ported enclosure, refer to the tuning
chart on the back for porting procedures.
C. Connect the speaker leads from the woofers to the terminal cups.
Be sure to wire the positive to red and the negative to black.
D. Align the mounting holes on the driver with the recesses in the
Q-Ring. If necessary, rotate the Q-Ring and the driver to properly
align printing on the dustcap.
E. Using the supplied screws, securely mount the driver in the
enclosure. It is recommended to start all screws and then come
back and retighten screws to prevent the driver basket from being
bent or distorted during mounting.
A. Experiment to find the best location for your new subwoofer system. Subwoofers for hatchbacks can
fire either upward, forward or backward for the best sound. Positioning makes a big difference in
sound quality.
B. FLYING SPEAKERS ARE DANGEROUS!! Permanent mounting is not only the safest installation, but
usually produces the best sound quality too. However, if you decide to mount your speakers so that
they can be easily removed, there are many suitable types of brackets available at most hardware
stores. The key to selecting such hardware is to make sure that the mounting will hold the speaker
securely. Good luck and enjoy your new subwoofer!
