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.
