XNBP SERIES GUIDELINES
Enclosure Guidelines
We at Dual have provided placement recommendations and installation tips for your
enclosures. These are a result of many hours of development 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. We
also recommend that you will have the best results by consulting a professional installer,
but If choosing to do your own installation, please note the following:
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 tie downs and wire clamps to prevent the wires from getting caught or shorted.
We do not recommend placing or installing band pass enclosures where they might be
subjected to moisture.
Correct subwoofer polarity must be observed. The polarity positive side is marked by a
(+) sign. Subwoofers out-of-phase will have little bass output.
Correct 12 volt polarity for lighting elements must be observed. Failure to maintain
correct polarity will not provide the needed DC power needed to illuminate the lighting
elements. Illumination inputs are 12 volt only. Do not connect an amp or any audio
output source to the lighting (Illuminite) inputs. Doing so will cause permanent damage
to the lighting elements.
Speaker wire should be isolated from the vehicle's electrical system to avoid noise
being picked up by the amplifiers.
Speaker wire should be large enough to carry the full power of your amplifier. 14 gauge
or larger sizes are adequate.
Be sure to give your ears consideration. Listening to loud music for extended periods
can possibly damage your hearing!
