The SounDigital EVO PS 800.4 is a compact, high-efficiency 4-channel amplifier engineered for motorcycle audio systems where space is limited but clean, punchy output is essential. Delivering up to 4 × 200 W RMS @ 2 Ω or 2 × 400 W RMS bridged @ 4 Ω, this amp is ideal for powering front and rear stages, pro-audio coaxials, or mid-bass drivers in Harley Touring builds.

  • 4 × 132 W RMS @ 4 Ω or 2 × 400 W RMS bridged for flexible system design.
  • Compact Class-D topology designed for motorcycle charging systems.
  • High-level & low-level inputs for easy OEM or aftermarket integration.
