INTRODUCTION

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.

IMPORTANT! Before making any connections, disconnect the car’s battery until the

installation is completed to avoid possible damage to the electrical system.

Fuse 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.

SPEAKER CONNECTIONS

IMPORTANT! The following speaker connection are for the amplifier in normal mono

configuration.

Make the speaker connections using speaker wire that is at least 16 gauge or heavier.

As with any audio component, proper phasing of the amplifier and speakers is essential

for strong bass response. When connecting, make sure that positive (+) from the amplifier

is connected to the positive (+) of the speaker, and the same for negative (-).

Please note that although the A1 500 , and A1 750 are mono amplifiers, we have

provided two sets of speaker terminals on the amplifier. These terminals are connected in

paralleled internally (connected together). The second set of speaker terminals are

intended for ease of connection when running multiple woofers.
