With the sophisticated CRE400.4DSP, Crunch offers an exceptional 6-channel sound processor with pre-installed presets that integrates an analog 4-channel power amplifier in an extremely compact housing. Thanks to the integrated Bluetooth module, the device also enables wireless music streaming - a real highlight in this class. In short: The mini DSP amp offers the option of operating front and rear systems, while an additional RCA output allows the connection of another amplifier for a subwoofer via the DSP - and all at an unbeatable price! 

The Crunch DSP impresses with incomparable audio quality, which is made possible by the integrated analog-digital converters from the renowned luxury manufacturer AKM - components that are otherwise often only found in significantly more expensive devices. With an extremely low THD value of just 0.03%, the amplifier guarantees crystal-clear sound reproduction. Thanks to a slope of up to 48 dB per octave and integrated time correction, precise adjustments are possible for an absolutely perfect sound experience. The parametric 31-band equalizer offers maximum flexibility to shape the sound exactly according to your own preferences. Brilliant - Crunch has three solutions for DSP programming: 

The classic method is done as usual via a PC using Windows software. Alternatively, the sound processor can also be programmed wirelessly using the DSP MASTER APP software for iOS or Android. This means that changes to the DSP can be made quickly or presets can be called up while on the go without having to connect a PC every time.


The alternative Crunch set CRE400.4DSP-ISO offers the convenience of connecting the amplifier to many car radios using the ISO cable that is included and is one meter long. In addition, Crunch offers a further 29 Plug+Play Variants (M1 to M29) ​with  ISO.M adapter cables, which have been optimally adapted to your vehicle.
