P500X2

The Rockford Fosgate P500X2 from the Punch series is a powerful 2-channel Class A/B amplifier that combines high output power with precise sound reproduction and versatile adjustment options. With up to 2 × 250 watts RMS at 2 ohms or 500 watts RMS in bridge mode, this amplifier is suitable for both high-quality speaker systems and high-power subwoofers.

Thanks to the built-in Punch EQ2 tone control, the bass and treble ranges can be adjusted individually. The adjustable high-pass and low-pass filters allow for flexible tuning to accommodate different speaker configurations. The built-in C.L.E.A.N. system with clipping indicators helps ensure proper level settings and prevents signal distortion.

The P500X2 features high-level inputs with an automatic power-on function, RCA outputs for routing the audio signal, and comprehensive protection circuits. The solid aluminum housing ensures reliable heat dissipation, while the concealed control panel provides a clean, uncluttered appearance.
