Maybe the headunit's INTERNAL amp begins to clip when you turn it up. Did you look at the amp rack? He's got an amp for the full ranges so the only thing the headunit is even used for is signal processing and then it sends out all sound via pre-outs so no clipping. On my headunit, there's even an option to turn off the headunits internal amp if you're using only the pre-outs to drive other amps so the signal is cleaner since you're not running the internal HU amp.Its not clip free, pioneers start to clip at 48.
Most people usually run them at 45/62
