NTRODUCTION

Congratulations on your purchase of a DB Drive state-of-the-art power amplifier. 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 amplifier 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 amplifier’s performance is only as good as its installation. Proper installation will 

maximize 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.

Due to continuing product improvements and possible manual revisions, we recommend 

checking our website for latest product information at www.dbdrive.net.

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 hearing loss or 

damage. 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.

AFETY PRECAUTIONS

F

use amplifiers power wire at the battery

Be sure to fuse the power wire within 12” of the car’s battery. This will protect the car’s 

battery in case of a short circuit between the power amplifier and battery. THIS IS A 

MUST, the amplifier’s built-in fuse will only protect the power amplifier not the car’s 

battery!

Use high grade wire connectors

To ensure maximum power transfer and secure safe connections, it is recommended to 

use high grade barrier spades (for connection at amplifier) and terminal rings (for connec-

tion at battery).

Do not run any wires underneath vehicle

Exposed wires have a chance of being cut or damaged. It is best to run all wires through 

the vehicle under the carpet and/or side panels. This lends to a cleaner installation and 

less risk of damage.

Use caution when mounting amplifier

Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as 

a gas tank in the automobile. Make sure you now where they are when mounting the 

amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank.

Run signal wires away from electrical wires

To avoid possibility of induced noise from the car’s electrical system (i.e. popping noises 

or engine noise), run wires away from the car’s electrical wiring.

Make all ground wires as short as possible and at the same point

In order to reduce the chance of ground loops (i.e. engine noise), make the grounding 

wire as short as possible to reduce the wire’s resistance. Also, when using multiple 

components, make sure all units are grounded at the same point.

Avoid sharp edges when running the wires

To avoid the possibility of power, signal or speaker shorts, be careful not to allow the 

amplifiers wires to come in contact with sharp edges. Use a grommet to protect the wire 

when running through the fire wall.
