Frequently Asked Questions - W2AC200 Auna

How to connect the W2AC200 amplifier to a car battery?

Connect the red wire to the positive terminal of the battery via the fuse holder, the black wire to ground (bare chassis), and the orange wire to a switched power cable from the radio for remote turn-on.

What is the minimum compatible speaker impedance?

This amplifier works with speakers of 4 to 16 ohms, but an impedance of 2 ohms is tolerated (watch out for overheating).

How to adjust the input sensitivity (GAIN)?

Set the GAIN potentiometer so that the input voltage matches that of your car stereo. High-level input: 1.0-2.0 V; low-level input: 0.1-1.0 V. Avoid setting too high to limit distortion.

What to do if the amplifier does not turn on?

Check the connections: red wire to battery, black to ground, orange to a switched 12 V. Check the ATC fuse on the device and the main fuse on the power cable.

Can I connect a subwoofer in bridged mode?

Yes, use the CH1+ and CH2- terminals for bridging. Connect a subwoofer with a minimum impedance of 4 ohms. The total impedance seen by the amp will be 2 ohms.

How to use the low-pass filter (LPF)?

The X-OVER selector allows choosing between FULL (full range) and LPF (low-pass). The LPF potentiometer adjusts the cutoff frequency from 30 Hz to 250 Hz, ideal for a subwoofer.

What power cables to use?

Use cables with a cross-section greater than 3 mm² to handle the maximum current of 7.5 A. A cable that is too thin can overheat and cause voltage drops.

The amplifier gets very hot, is this normal?

Yes, this amplifier can get hot during operation. Ensure adequate ventilation during installation, do not cover it, and leave free space around. If the thermal protection engages, reduce the volume or improve ventilation.

How to clean the amplifier?

Use a dry microfiber cloth to dust. Never use chemicals, water, or alcohol, as they could damage the circuits.

Can I use the amplifier with the engine off?

Yes, but the battery will drain quickly because the amp draws up to 7.5 A. It is recommended to run the engine to avoid a dead battery.

DEVICE PROPERTIES

Audio

• Auna Car Amplifier acrylic black & blue LEDs with 2000W
• 90W x 2 channel output power (20Hz - 20KHz, into 2 ohms)
• Multiple mode for simultaneous operation of subwoofer and satellite speakers
• Adjustable subwoofer crossover frequency (30-250Hz)
  • High-current output device
• Adjustable RCA input level
• Basic input isolation for suppression of wire interference

Energy supply

• Ultra-stable PWM (pulse width modulated signal)
  • Energy supply (11-16 V)
  • thermal overheating protection
• Remote activation

General Information

• Noise reduction
• Switch-on delay
• Speaker short-circuit protection
  • Gold-plated cinch connections and inputs
• ATC fuse on the device

CONNECTION INSTRUCTIONS

1. Connecting the power cable

• As this is a high-current device, the correct connection of the power cable is very important.
• Connect the red cable to the (+) terminal of your battery using the cable with the fuse holder.
• Connect the black cable firmly to a screw or another part of the bodywork of your car after you have removed the coating from this area. This is necessary for proper earthing.
  • Proper wiring results in clear sound.

2. Connection of the remote on/off cable

• Connect the orange cable to a switched power cable of the car radio. This controls the switching on and off of the amplifier.
• The cable for the automatic antenna on the radio (if present) can be used for this purpose.

3. Amplifier input connection

• This device can be used with all car radios that have high power outputs.
• Separate basic car radio connection: Connect the car radio speaker output cables to the high-power inputs +/- right and left.
• General car radio connection: Connect the negative car radio speaker output cable to the two remaining cables +/- right and left.

4. Connecting the AUX port:

• Connect the AUX input cable to the cinch connector as described: "White" to the left cinch output and "Red" to the right cinch output of the car radio.
• Before connecting the RCA output of the car radio or other equipment, make sure that the impedance and sensitivity match this AUX connection.

5. Input sensitivity control

- Adjust the input sensitivity to match the output signal of the car radio.

6. Connecting the speakers (stereo & mono)

- Connect the speakers as shown in the illustration.

Important instructions

• The amplifier requires 7.5A at maximum power. If the amplifier is being used while the engine is switched off, the battery may be discharged. Please always switch on the motor before using the amplifier.
• Only use power cables with a suitable cross-section (larger than 3 mm ^2 ).
• This device is suitable for speakers with an impedance of 2-16 ohms. The speakers must have enough capacity to accommodate the power of the device.

CONNECTION TO THE RADIO

BLACK (black) To the (-) pole of the battery or another ground point

ORANGE (orange) Remote activation

RED (red) To the (+) pole of the battery

ASSEMBLY OF THE APPLIANCE

Assemble the amplifier using screws as described in the illustration.

Important instructions

• The appliance heats up considerably.
- Therefore, please leave enough space for ventilation around the amplifier when assembling it. Do not cover the amplifier during operation.
