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.
