INTRODUCTION
SAFETY PRECAUTIONS
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.
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 connection 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
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.
Serial # ___________________ Model # _______________________

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.
FEATURES AND BENEFITS
Line out
DC Offset Protection
This circuit protects the output of the amplifier against DC voltage. If for some reason DC
voltage is detected at the output stage, the amplifier will shut down protecting the speakers
from direct current.
Short Circuit Protection
The circuit protects the amplifier from damage due to a short found in the speakers or
wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will
shut down. To resume normal operation, correct the problem and turn the head unit off, then
back on. The amplifier will reset and play again.
Thermal Protection
To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The amplifier will automatically turn back on once it cools down to a safe
operating temperature.
Power Indicator
The diagnostic L.E.D. illuminates when the amplifier is on and receiving power.
Built-in Crossover
The “Speed Series” amplifiers include a built-in variable crossovers. The crossover features
a variable frequency selection for precise low pass filtering for the SPA1000D, SPA1300D ,
SPA1600D and SPA1900D. The SPA90.2 , SPA90.4 and SPA150.4 also offer the same
frequency selection with the option of low or high pass filtering.
Full range line outputs have been provided for convenient connection to additional amplifiers in the system. The outputs are buffered to reduce signal loss. Please note that the
amplifier’s input level adjusts these level outputs.
Power Fusing
This protects the amplifier against short circuits and excessive current.
Remote Turn-on
Automatically turns amplifier on when connected to the head unit’s remote output. The
amplifier will turn on and off with the head unit to save current consumption. This control
also operates the reset circuit for the amplifier’s protection. It must be connected with the
head unit in order to reset protection circuits.
Adjustable Input Sensitivity
Allows you to fine-tune the level matching between your source and the power amplifier.

MOUNTING LOCATION
Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to
dissipate the heat it develops during operation. Two popular mounting locations are in the
trunk or under the seat.
Select the location in which you wish to mount the amplifier. Use caution when mounting
amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank
in the automobile. Make sure you know where they are when mounting the amplifier to
avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready,
use a pencil to mark the mounting holes in the bottom panel. After you have marked the
locations of the holes move amplifier out of the way and drill small starter holes to make the
tapping screws easier to install. Use provided screws to tighten down the amplifier.

IMPORTANT! Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system.
Connect the amplifier to the car’s battery
At times, the amplifier will need to draw large levels of current that cannot be provided by
any circuit in the car’s fuse box. We recommended using a 4 to 8 gauge power wire for your
connections depending on the amplifier and length of the wire. Strip one end of the wire to
connect to the terminal on the amplifier marked “batt+”. Loosen screw terminal and connect
bare wire and tighten. Use caution to make sure no stray wire strands come in contact with
surrounding terminals causing short circuits. Run the wire directly to the positive terminal of
the car’s battery. Make sure to use an in-line fuse within 12” of the car’s battery to protect
the electrical system and amplifier against short circuits and/or power surges.

For the ground connection, use a 4 to 8 gauge wire (black) to connect to the terminal
marked “ground” and then connect it to the car’s chassis. Try to keep the length of the cable
as short as possible, preferably less than 6”. Also make sure that the point on the car where
the connection is to be made is free of paint and dirt.
Connect the remote terminal of the amplifier to a switchable +12V source
This connection allows the amplifier to be turned on and off with the power control of the
radio. If the radio has a REMOTE output terminal, connect it to the amplifier’s terminal
marked “remote” (using a 16 gauge wire or heavier). Now when the radio is turned on, the
amplifier will automatically turn on. This connection can also be made to the radio’s Power
Antenna wire.

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 SPA1000D, SPA1300D , SPA1600D and SPA1900D 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.
