DS - XS SERIES 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.
• 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!
