B2 Audio 2500W 1-Ohm Class D Monoblock Amplifier w/ RGB LED Lights RIOT Series
This Listing Includes:
- (1) B2 Audio Riot Series 2500 watts Monoblock Amplifier with RGB LED Lights
The RIOT Series Monoblock Amplifiers are built to deliver serious power, efficiency, and reliability in a compact footprint. Designed around a half-bridge Class D topology, this amplifier provides stable, consistent output while keeping heat generation and electrical strain under control—making it an excellent choice for daily-driven systems and high-output bass setups alike.
With up to 2500W RMS at 1 ohm, the RIOT 2500 balances strong low-frequency performance with dependable operation across a wide range of electrical systems. The integrated RGB LED lighting adds a clean, professional look to your install, with selectable sound-activated patterns or the option to turn lighting off completely.
For best results, we recommend upgrading your vehicle’s electrical system. A stronger charging and battery setup helps ensure maximum output, improved stability, and long-term amplifier reliability.
Why a Half-Bridge Class D Design?
The RIOT Series uses a half-bridge Class D architecture, which is well-known for its balance of efficiency, durability, and electrical friendliness.
Key advantages of a half-bridge design include:
- Improved reliability under demanding loads by reducing component stress
- Lower heat output, helping the amplifier run cooler during extended play
- Efficient power delivery, making better use of available voltage
- Better compatibility with stock and mildly upgraded electrical systems
This design allows the amplifier to deliver strong, clean bass performance while maintaining consistent operation - especially important in real-world daily-use applications.
Features
- Input: RCA Signal Input for Left & Right Channel. A minimum of 0.2V input is required for correct operation.
- Power & Protection Indicator: Power LED, Blue light shows correct operation. Protect LED, Red light shows a general malfunction, a faulty connection, or thermal protection.
- Clip Indicator: The LED will light up if the signal is clipped. An occasional flashing light is acceptable, a constantly lit diode is not.
- Flash: Enables the sound-activated LED sequences with multiple patterns and colors. The LED can be switched off by keeping the button pressed for a few seconds.
