B2 Audio 1800W 2-Ohm Class D Half Bridge 4ch Amp w/ RGB LED Lights RIOT Series
This Listing Includes:
- (1) B2 Audio RIOT Series 1800 Watt 4-Channel Amplifier with RGB LED Lights
The B2 Audio RIOT Series 4-Channel Amplifier is engineered for efficient power delivery, system flexibility, and long-term reliability in a compact chassis. Built on a half-bridge Class D topology, this amplifier delivers strong, consistent output while minimizing heat buildup and electrical strain—making it well suited for daily-driven systems and space-conscious installs.
With flexible channel configurations, the RIOT 1800 can be used to power mids and highs, run active front stages, or bridge channels for higher-output applications. Integrated RGB LED lighting adds a clean visual upgrade with selectable sound-activated patterns or the option to disable lighting entirely for a stealth install.
For optimal performance and stability, upgrading your vehicle’s electrical system is recommended, especially when operating the amplifier at lower impedances or higher output levels.
Why a Half-Bridge Class D Design?
This amplifier uses a half-bridge Class D architecture, chosen for its balance of efficiency, durability, and real-world electrical compatibility.
Benefits of a half-bridge design include:
- Reduced heat generation, allowing the amplifier to run cooler under load
- Lower component stress, improving long-term reliability
- Efficient power usage, making better use of available system voltage
- Stable operation with stock or mildly upgraded electrical systems
The result is a 4-channel amplifier that delivers clean, controlled power while maintaining dependable performance in everyday applications.
