The attractive Riot Series is a 400 Watts 4 Channel Full Range, Class AB Amplifier generates a maximum of 400W power with a minimum 2 ohm impedance. Full range class AB amplifiers easily power door speakers or subwoofers and have the capability to generate high quality sound with minimal distortion. Class AB amplifiers are extremely linear and have reduced distortion but are not as power efficient as Class D amplifiers. Enjoy superior sound!

This four channel amplifier is not capable of being bridged so it must be used as a four channel amplifier for your interior speakers. The built in thermal protection circuits turns off and lets the amplifier cool down to prevent damage. Additional features like the Speaker level inputs, Variable gain control, provides the user with a clean input signal with an aftermarket or stock audio system.
