XOBP12D GUIDELINES
Enclosure Guidelines
To achieve the best possible sound from this subwoofer enclosure, Dual recommends aquiring the services of a professional car audio installation center.
If you feel confident in your ability to install this product without the assistance of a professional, please read this section thoroughly. We have provided a number of placement recommendations and installation tips to assist you. Keep in mind these are provided as a guideline and you may find that other placements specific to your vehicle may provide better results.
Make sure all moving parts and factory electrical wires are out of the way and will not interfere after installation.
Ensure the wire is of sufficient length to avoid pulling or stretching. This is even more important if the wires will be run under or through the factory interior.
Use electrical tape and wire ties to ensure all wires are properly secured.
Avoid installing speakers or electronics where they can be subject to moisture.
Ensure the speaker wires are connected using correct polarity. The positive polarity is marked by a (+) sign. Incorrectly connected subwoofers will result in limited bass output.
Ensure the Illuminite wires (12V) are connected using correct polarity. Do not connect an amplifier or any audio output source to the Illuminite inputs as 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.
We recommend using 14 gauge or larger sized speaker wire to ensure your subwoofer receives the full power output of your amplifier.
Remember to listen responsibly and respect your ears. Being exposed to sounds over 125dB for even short periods of time can create permanent hearing loss!
