The following placement recommendations and installation tips are the result of many hours of devel-
opment and experimentation. These examples are provided to you as a guide line. Please feel free to
experiment yourself as you may find that other placements can provide you with superior results.
• Make sure all moving parts and factory electrical wires are out of your way and will not interfere
after installation.
• Leave a little slack in the wire to prevent pulling or stretching, this is even more important if the wires
will be run under or through the factory interior.
• Use cable ties and wire clamps to prevent the wires from getting caught or shorted.
• We do not recommend placing or installing loaded enclosures where they might be subjected to
moisture.
• Correct subwoofer polarity must be observed. The polarity positive side is marked by a (+) sign.
Subwoofers wired out of phase will produce little bass.
• Speaker wires should be electrically and physically isolated from the vehicle and routed away from
any factory wiring that carries high currents or noise (ie, ABS brake systems and engine computer
signals).
• Use speaker wire large enough to carry the full power of your amplifier. 14-gauge or larger should
be adequate. (Speaker wire not included)
Your PowerBass Bass Reflex subwoofer system needs to be installed some place where it can oper-
ate efficiently and not endanger the occupants of the vehicle.
The location and orientation of your enclosure will affect the quality and quantity of the bass. The
port tube (vent) openings cannot be obstructed. At some frequencies most of the bass will come out
of the port tube. Therefore we recommend you leave at least 3-inches (7.62cm) between the port
tube openings and interior surfaces such as side panels, seats and doors.
If the enclosure is to be mounted all the way in the back of the vehicle, it works best to point the
woofer toward the front of the vehicle. Conversely, if the enclosure is going to be mounted closer to
the back seat, pointing the woofer toward the rear of the vehicle will give you the best results. Even
when the enclosure is placed inside a car trunk with no opening to the passenger compartment, the
Bass Reflex design will produce strong and full bass.
