Introduction

Congratulations on your purchase of a DB Drive state-of-the-art subwoofer. Your selection of a

DB Drive car audio product indicates a true appreciation of fine musical reproduction. Whether

adding to an existing system or including your DB Drive subwoofer in a new system, you are

certain to notice immediate performance benefits.

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

establish purchase date.

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(2). 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.
