Bedienungsanleitung

The B² Audio RIOT 2500.1RGB was designed for high-performance subwoofer systems and combines high output power with a compact design. Thanks to efficient HI-EF Class-D technology, the monoblock delivers impressive performance while maintaining high energy efficiency and low heat generation. The integrated RGB lighting gives the amplifier a modern look and makes it particularly appealing for show and performance vehicles.

To ensure optimal adaptation to a wide variety of subwoofers, the amplifier offers extensive adjustment options such as a low-pass filter, subsonic filter, continuously variable phase control, and bass boost. The included bass-level remote control, featuring a clip indicator and voltage display, simplifies level adjustment and helps detect clipping early on. High-quality connectors and a generously sized power connection ensure a reliable power supply even under high-power demands.

Frequently asked questions about the B² Audio RIOT 2500.1RGB amplifier

How do I connect the B² Audio RIOT 2500.1RGB to my subwoofer system correctly?

The amplifier is connected to the radio via the RCA inputs. Connect the speaker outputs directly to your subwoofer. Make sure that your subwoofer’s impedance matches that of the power amplifier – at 1 ohm, the RIOT achieves its full power output of 2,500 watts RMS.

What power supply does the RIOT 2500.1RGB amplifier require for optimum performance?

To ensure maximum power output, you should use a power cable with a cross-sectional area of at least 50 mm². A stable supply voltage of 14.4 V and a suitably rated fuse are essential. The earth lead should be of the same thickness and kept as short as possible.

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

The RGB lighting automatically cycles through different colours. It is controlled directly via the power amplifier. This model is factory-set to allow for manual colour adjustment or synchronisation with other RGB components.

Does the B² Audio amplifier get hot when running continuously at full power?

Thanks to the efficient Class D technology, heat build-up remains within acceptable limits even under heavy load. The housing acts as a heat sink. In the event of extreme continuous load, additional ventilation in the installation area is recommended to ensure optimum operating temperatures.

What is included in the box with the RIOT 2500.1RGB?

The amplifier comes with all the necessary connection terminals and a user manual. You will need to purchase the power cable, fuses and RCA cables separately. The mounting screws required for installation are also included in the pack.

Is the RIOT 2500.1RGB also suitable for competitive use?

Absolutely – B² Audio has designed the RIOT series specifically for competition use. With 2,500 watts RMS at 1 ohm, the power amplifier delivers enough power for SPL competitions. Its robust build and reliable electronics make it the ideal choice for competitors.

How big is the RIOT 2500.1RGB, and will it fit under my car seat?

The power amplifier stands out for its compact design. You can find the exact dimensions in the technical specifications. Its slim profile often makes it possible to fit it under front seats or in the boot of vehicles where space is limited.

Can I combine several RIOT amplifiers to create a larger system?

Yes, you can run several RIOT power amplifiers in parallel. For multi-channel set-ups, or if you need even more power, the amplifiers can be combined without any problems. Just make sure there is a sufficient power supply for all components.
