Product Description
Whether as a classic 4-channel system, a 3-channel configuration with subwoofer, or a bridged 2-channel layout: the 204 adapts flexibly to a wide range of vehicles and system requirements. With an output of 4 x 100 watts RMS at 4 Ω, 4 x 190 watts RMS at 2 Ω, or 2 x 380 watts RMS bridged at 4 Ω, it delivers more than enough power for ambitious setups.
Available as an X-OVER version with integrated active crossover or a DIRECT model optimized for pure signal transmission via external DSPs – always with a focus on superior sound performance.
