Keep Your Sales Receipt
Take this time to attach your sales receipt to the manual and put in a safe place. In case of any
unforeseen reason this product may need warranty service, your receipt will be necessary to

Recommendation
A power subwoofer’s performance is only as good as its installation. Proper installation will max-
imize the system’s overall performance. It is recommended that you have our product installed
by an authorized DB Drive retailer. However, if you decide to install it yourself, please carefully
read through this manual and take your time to do a quality installation.
IMPORTANT!
Before making any connections, disconnect the car’s battery until the installation is
completed to avoid possible damage to the electrical system.
WARNING!
Exposure to high power sound system can cause hearling loss or damange. Listening
to your system at loud levels while driving will impair your ability to hear traffic sounds
and emergency vehicles. Use common sense when listening to your system.

PRODUCT SPECIFICATIONS
CALCULATING ENCLOSURES
It is recommended to build your enclosure from at least 3/ 4” thick MDF (medium density fiber-
board). Make sure the enclosure is sealed airtight.
Calculating External Volume
To calculate box volume, measure the outside Width x Height x Depth of
the enclosure. Example 12” x 14” x 9”=1512 ÷ 1728” Cubic feet
Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inches total by 1728”. Example 1512 ÷ 1728=.875 Cubic feet
Calculating Internal Volume
To calculate the internal (net) volume of the above box you must first multiply
the thickness of the wood you are using by Two. Example 3/4” x 2= 1.5“
Next subtract 1.5 from each of the outside measurements of the box.
Width Height Depth
12 - 1.5 = 10.5 14 - 1.5 = 12.5 9 - 1.5 = 7.5
Multiple the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = .5696
Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inch total by 1728”. Example 984.375 ÷ 1728=.5696
cubic feet.
