RECOMMENDATION

An amplifiers perfomance 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 DRIVEN retailer. If you decide to install it yourself, please carefully read through this manual and take your time to do a quality installtion.
Due to continuing product improvements and possible manual revisions, we recommend checking our website for the latest product information at: www.drivenelectronics.com

IMPORTANT! Before making any connections, disconnect the vehicle’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.

SAFETY PRECAUTIONS

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

To avoid possibility of induced noise from the ca(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

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 DRIVEN DRAB, DRA4 and DRA2 are equiped with a built in variable crossover network allowing you to select the crossover function and frequency for each the front channels or rear channels of the amplifier independently.

The DRIVEN DRA3000.1, DRA2000.1 and DRA1000.1 Monoblock Amplifiers are equipped with a built in variable lowpass crossover network allowing you to select the crossover function and frequency for each the front channels or rear channels of the amplifier independently.

Power and Speaker Distribution Blocks

Heavy gauge bare wire distribution blocks are provided for maximum power and signal transfer with minimal resistance.

LOW IMPEDANCE STABILITY

Full range line outputs have been provided for convenient connection to additional amplifiers in the system. The outputs are buffered to reduce signal loss.

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. 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 withthe 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.

LOW IMPEDANCE STABILITY

BUILT-IN CROSSOVER

DRA4,DRA8

The DRA4 and DRAB amplifier allow you to select the crossovermode (High-Passfull Range or Low Pass/ Band Pass)and desired crossover point for channels 1-2 and 3-4.

For example if you wish to use a 2-way loud speaker on channels 1-2, simply set the crossover switch to HPF and adjust the frequency setting to the desired HPF setting to block out any unwated low frequencies.

block out any unwated low frequencies.
If you wish to run a subwoofer on channels3-4,simplysetthe crossoverswitchto LP/BP.
You must adjust the HPF Frequency setting to 50 Hz and the LPF Frequency setting to the desired Low Pass setting to block out unwanted high frequencies.

If you wish to run a component midrange on either channels 1-2or 3-4setthe crossover switch to LP/BP.Then use both HPFand LPFfrequency controls to create the desired band pass frequency range.

THESE SETTING CAN BE USE ON CHANNELS 1-2 OR 3-4
INDEPENDENTLY OR FOR ALL CHANNELS

Power Connection Leads

Notes on the Power Supply

the ground wire of the unit securely to a metal part of the car. A lose connection may cause a malfunction of the amplifier.

REMOTE:The unit is turned on by applying+ 12Volts to this terminal. This terminal does not draw heavy current like the two power terminal so a thinner connecting wire is acceptable. Standard 18 GUAGE is fine and the standard color is yellow. If the power antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio. Use the power supply lead with a fuse attached whose value is the same as original fuse.
Place the fuse in the power supply lead as close as possible to the car battery.

During a full power operation. Maximum current will run through the system. Therefore,Make sure that the leads to be connected to the+ 12Vand GND terminals of the unit respectively must be larger than 10-Guage(AWGl0).

Power Connections

IMPORTANT! Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system.

1. It is important that you read this manual very carefully and follow it for your installation carefully. Before you start your installation,please consider following concerns. Check the battery and alternator ground(-) connections. Make sure they are properly connected and free of corrosion.
2. Before selecting a mounting location for amplifier, please take some concerns into consideration with cooling efficiency and safety.
3. Power connection
   Before installing amplifier,disconnect the negative(-) wire from battery to protect any accidental damage to your amplifier and System.This Amplifier is designed to use 4 AWG POWER and GROUND cables.
4. Ground connection
   Locate a secure grounding connection as close to the amplifier as possible. Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle.Connect one end of a short piece of the same size cables as the power cable to the grounding point.Run the other end of the cable to the amplifier mounting location. Connecting the ground cable to the screw terminal labeled as GND.
5. Remote connection
   Run a remote turn on cable from the switched+ 12V source you will be using to turn on the system components. This may be a toggle switch, a relay, or your source unit’s remote trigger wire, or power antenna trigger wire. Connect the remote turn on cable to the power terminal labeled as REM. Run this lead to the amplifier mounting location. Using 16AWG wire or larger.
