Wiring Wizard & Port Calculator

Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!

Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.

Bedienungsanleitung

The B² Audio RIOT 1800.4RGB combines high output power, modern Class D technology, and a compact design for high-performance car audio systems. With up to 4 × 450 watts RMS at 2 ohms, the amplifier is ideal for high-performance front and rear systems, as well as for bridge mode to drive powerful subwoofers. The integrated RGB LED lighting behind the acrylic cover creates a unique look and makes the amplifier a visual highlight as well.

The Class D design, engineered for high efficiency, reduces heat generation and ensures reliable operation even at high power levels. High-quality high-pass and low-pass crossovers, a high damping factor, and a generously sized power connection provide the ideal conditions for precise sound reproduction and a stable power supply.

Frequently asked questions about the B² Audio RIOT 1800.4RGB amplifier

How much power does the B² Audio RIOT 1800.4RGB deliver at different impedances?

The 4-channel amplifier delivers an impressive 1,800 W RMS total output. At 2 ohms, it delivers 4 x 450W RMS per channel, whilst at 4 ohms it still provides a robust 4 x 225W RMS. This power makes it the ideal choice for high-performance car audio systems.

Can I use the RIOT 1800.4RGB to power both speakers and subwoofers?

Yes, the amplifier is very versatile. You can use it in 4-channel mode for four speakers, or in bridged mode with two channels for subwoofers and two for tweeters. The flexible configuration allows you to tailor it perfectly to your car audio setup.

How does the RGB LED lighting work, and can I customise it?

The RGB LED lighting on the B² Audio RIOT amplifier can be customised. You can choose from a range of colours and effects to create your own personalised atmosphere. The lighting can also be switched off completely if you prefer a more understated look.

What are the amp’s dimensions, and will it fit into compact installation spaces?

The RIOT 1800.4RGB has been deliberately designed to be compact. Thanks to its optimised dimensions, it can be fitted even in confined spaces within a vehicle. Its precise dimensions allow it to be installed under seats or in small boot compartments without compromising on performance.

How complicated is it to install the B² Audio RIOT amplifier?

Thanks to its well-thought-out design, installation is straightforward. All connections are easily accessible and clearly labelled. For best results, we recommend using high-quality cables with a sufficient cross-section. A qualified technician can carry out the installation in around 2–3 hours.

Does the RIOT 1800.4RGB have any special protection circuits?

The amplifier is equipped with comprehensive protection circuits against overheating, short circuits and overloads. These safety features protect both the amplifier and your connected components. The protection circuits operate automatically and ensure safe, long-term operation.

How does the amplifier perform on long journeys and under heavy load?

Thanks to efficient Class D technology and optimised cooling, performance remains stable even under continuous load. The RIOT 1800.4RGB is designed for professional use and delivers consistent performance without any thermal issues, even after hours of operation.

What accessories do I need to get the most out of the amplifier?

For the best results, you should use high-quality power cables (at least 50mm²), suitable fuses, RCA cables and speaker cables. A capacitor can provide additional power reserves during passages with extreme bass. A remote cable and earth connection are also required.
