Banda BD800.4 800W RMS 4-Channel Car Amplifier 2 Ohms
Banda BD800.4 800W RMS 4-Channel Car Amplifier 2 Ohms
Flexible four-channel power for your car audio upgrade
The Banda Audioparts BD800.4 delivers a listed total of 800W RMS at 12.6V, with four channels rated at 200W RMS each into 2 ohms. Prefer a bridged configuration? It also offers two outputs rated at 400W RMS each into 4 ohms at the same supply voltage.
Plan a system around your speakers rather than a single power figure. The BD800.4 gives your installer four-channel and bridged options, helping you build a compatible setup for your next listening session.
Key Benefits
- Four-channel amplification for flexible car audio layouts.
- Bridgeable operation for two compatible 4-ohm loads.
- Listed frequency response of 20Hz–20kHz (-3dB).
- High-pass and low-pass filtering for system configuration.
- Compact listed dimensions of 116 × 127 × 53mm.
Listed RMS Power Output
| Configuration | Load | At 12.6V | At 14.4V |
|---|---|---|---|
| Four channels | 2 ohms per channel | 4 × 200W | 4 × 230W |
| Four channels | 4 ohms per channel | 4 × 120W | 4 × 150W |
| Two bridged outputs | 4 ohms per bridge | 2 × 400W | 2 × 460W |
The 800W RMS figure is total output at 12.6V under the specified load conditions, not 800W per channel. Actual output depends on supply voltage and speaker impedance.

Compatibility and Installation
Have a qualified installer confirm speaker impedance, voltage, power requirements, bridge wiring, circuit protection, cable sizing, and ventilation before purchase. Verify filter details and all installation requirements against the manufacturer's documentation.
Do not operate below the specified minimum load. Installation must be performed by a qualified professional. Incorrect installation or misuse can damage the amplifier, speakers, or vehicle and may fall outside warranty coverage.
Choose the BD800.4 for a carefully matched four-channel or bridged car audio installation.
