CPX Series Power Amplifiers: Three rugged, ultra-affordable power designs in the great Crest Audio tradition.
In typical Crest Audio fashion, we've over-built and over-engineered the CPX Series. Especially considering their highly competitive prices.
We included built-in subwoofer crossovers, low-cut filters to prevent woofer cone flutter, fan cooling, Speakon output connectors and much, much more.Crest Audio's patented GCL Gain Comparator Limiting System

Gain Comparator Limiting.
When a signal has waveform peaks that exceed the amps power-supply rails, waveforms get chopped off, or clipped. This undesirable distortion most often happens when the amp is turned up too high (too much gain). GCL senses clipping (or current limiting) and dynamically reduces the gain for a few milliseconds. You can drive the CPX amp to its maximum (and beyond) without hearing audible distortion.
