CRUNCH GPX1600.1D

1-channel Class D digital mono amplifier, 400 watts RMS @ 4 ohms

CRUNCH Class-D mono blocks


Crunch GPX monoblocks have become true bestsellers in recent years. This is not surprising, as they are hard to beat in their respective price ranges. Crunch is now introducing two new, particularly powerful models in the 2025 line-up: The GPX1600.1D already delivers a powerful 1,600 watts max (800 WRMS), while the GPX5500.1D comes up trumps even more with an impressive 5,500 watts max (2,750 WRMS), making it the new top model in the series. The popular GPX power amplifiers are available in two versions: The GPX750.1D, GPX1250.1D and GPX1600.1D models with up to 1,600 watts already impress with top features such as high level inputs with auto turn on, phase shift, low pass and subsonic filter as well as bass boost. A bass remote is also included in the scope of delivery.
