Crunch GPX5500.1D

The Crunch GPX5500.1D is a high-performance digital mono amplifier from the GroundPounder GPX series, specifically designed to drive high-power subwoofers. With up to 2,750 watts RMS at 1 ohm, this monoblock amplifier provides ample power reserves for powerful bass systems.

In addition to its high output power, the GPX5500.1D offers extensive options for tuning the subwoofer. Low-pass and subsonic filters can be adjusted as needed, while bass boost and continuous phase control allow for further customization to suit the vehicle and subwoofer.

Thanks to its RCA and high-level inputs, the power amplifier can be connected to both aftermarket radios and many factory-installed audio systems. When using the high-level input, an automatic power-on function is also available. The master/slave function allows multiple compatible amplifiers to be linked together.
