The B2 Audio RIOT16000 is a full-bridge Class D amplifier designed for high-performance car audio systems, emphasizing both power and sound quality. It is part of the "RIOT" series, which aims to deliver superior performance and power in a compact size suitable for various vehicles.

Function Description:

The RIOT16000 serves as a powerful amplifier for loudspeakers and subwoofers in an automotive environment. It takes a low-level audio signal (RCA input) and amplifies it to drive speakers with significant power. The amplifier is designed to make a strong statement in terms of performance, pushing beyond standard expectations in car audio. Its full-bridge design means it is internally bridged and cannot be externally strapped or bridged with other amplifiers.

Power Terminal Gauge: 0 GA x 2
Fuse Rating: 1200 A (Peak Current Draw >1500 A) - external fuses required
Dimensions: 24.49" x 8.85" x 2.63" / 620 x 225 x 68 mm
Operational Voltage: 9V ~ 16V

Continuous Output Power (RMS):

At 13.8 V - 1% THD:
- 4 Ω: 7000 W
- 2 Ω: 10500 W
- 1 Ω: 16000 W
At 14.4 V - 1% THD:
- 4 Ω: 8500 W
- 2 Ω: 12500 W
- 1 Ω: 16000 W

Important Notes on Specifications:

The amplifier is not stable below 1 ohm impedance. Operation below minimum impedance will stress the amplifier and void the warranty, leading to excessive heat and thermal protection.
To achieve full power output, a correctly dimensioned electrical system is crucial.
All features are subject to change in the continuing effort to improve the products without notice.

Usage Features:

Panel Layout: The amplifier features a comprehensive panel layout for easy configuration.
- Input (RCA): Requires a minimum 0.2V input signal for correct operation.
- Output (RCA): Provides a signal output diverted from the amplifier's RCA input, useful for chaining other audio devices.
- Crossover High (12 dB/Oct): Variable high pass crossover from 10 Hz to 500 Hz. Recommended to set according to loudspeaker enclosure/T/S parameters to prevent strain on the sound system.
- Crossover Low (12 dB/Oct): Adjusts the cut-off point for the low pass crossover at the chosen frequency. Can be used simultaneously with Crossover High to create a bandpass crossover.
- Gain (5V - 0.2V): Adjusts the input voltage to match the amplifier's input stage. Voltages outside the 0.2V-5V range may cause errors or damage.
- Bass Boost Level: Control for 0-12 dB bass boost.
- Bass Boost Freq: Variable bass boost frequency from 35 Hz to 70 Hz. Not activated if level selector is set at 0 dB.
- Remote Level Control Port: Connects to an external signal level control with a clip indicator. This is not a volume knob and should be adjusted in accordance with the amplifier's gain.
- LED Status:
  - Power lit: Normal operation.
  - Clip lit or flashing: Signal input is not clean, and distortion is detected.
  - Protect: Amplifier has shut down due to improper application, malfunction, or circuit damage.
- Speaker Output: Connects to loudspeakers and/or subwoofers. Minimum impedance is 1 OHM. The RIOT16000 is a full-bridge amplifier and is internally bridged; it cannot be strapped or bridged externally.
Power Terminals:
- GND (Ground Connection): Connects to the vehicle's chassis. Must be as short as possible (< 20" / 50 cm) using a minimum 0AWG cable.
- OUT (Remote Output): Switched remote output for additional devices like other amplifiers or signal processors.
- +12V (Power Connection): Connects to the positive terminal of the battery. Requires 0AWG cable for specified performance. Fuses must be placed within 8" / 20 cm of the battery.
- REM (Remote Input): Switched remote input connection.

Maintenance Features:

Installation Considerations:
- Preparation: Disconnect the negative battery cable before any mounting or connections. Check battery and alternator ground connections for proper dimensioning and absence of corrosion.
- Mounting Location: Choose a dry, well-ventilated location that allows for vertical positioning of heatsink fins to avoid excessive heat. Avoid areas with excessive vibration or upside-down installation. Ensure no cables or harnesses interfere with the mounting location or pose a hazard to vehicle components (fuel lines, hydraulic lines, etc.).
- Cable Routing: Route RCA cables away from high current wires, and ideally run RCA, power, and speaker cables individually with good distance from each other.
- Power Connectors: All terminals (0 AWG power & ground) must be used with adequate cable. External fuses are required at both the battery and the amplifier ends of the power cable.
- Grounding: Locate a secure grounding connection as close as possible to the amplifier, ensuring it's clean and provides a direct electrical connection to the chassis. The ground cable should be as short as possible, no longer than 20" / 50 cm.
- Speaker Connection: Use minimum 10 Ga speaker cables for optimal performance. Route speaker cables separately from high current and RCA cables. Use grommets where cables penetrate the vehicle's chassis. Strip 3/8" / 1 cm of insulation, twist strands tightly, and use spade plugs or solder for solid terminals.
Troubleshooting Guide: The amplifier's protection circuits prevent severe damage from faulty conditions. If the protection indicator switches on, turn down all levels, power off, and check for:
- Amplifier Doesn't Turn On: Check +12V terminal voltage, remote terminal voltage (min. 13.8V DC), ground connection, and in-line fuses. Ensure protection LED is off.
- Protection LED Is Lit Once Amplifier Is Turned On: Check for shorts on speaker wires, connected load/impedance, power cables, and GND. Disconnect speaker cables and reset the amplifier. Verify operational voltage is within 9V-16V.
- Fuse Blowing: Measure speaker impedance (ensure it matches configuration) and inspect power cable for shorts with vehicle chassis.
- Overheating: Measure speaker impedance (ensure it matches configuration), check speaker shorts, and ensure sufficient airflow around the amplifier. Avoid installation in areas of excessive vibration or upside down.
- Audio Output Insufficient - Distorted Sound: Match gain settings with head unit output level, adjust head unit volume, check speaker shorts, adjust crossover frequencies, and check RCA connections.
- Turn On Thump: Disconnect signal input, then turn on/off. If noise cancels, connect a delay turn-on module on the REM wire or use another 12V source for the REM lead with a relay to isolate the amplifier.
- High Hiss - Engine Noise in Speakers: Ensure signal wires (RCA, speaker) are separate from power/ground wires. Bypass electrical components between head unit and amplifier. Remove existing ground wires for all electrical components and ensure ground point is 100% metal, free of rust/paint. Replace OEM battery/alternator ground cable. Test battery and alternator load and ensure vehicle's electrical system (distributor, alternator, spark plugs/wires, voltage regulators) is in good condition.
