HERTZ CP 1.2K

The HERTZ CENTO POWER CP 1.2K was developed for high-performance subwoofer systems and combines high output power with a compact design. Thanks to modern Class D technology, the amplifier operates particularly efficiently and generates very little heat, even at high power levels. The robust die-cast aluminum housing ensures optimal heat dissipation and allows for flexible installation even in tight spaces.

With extensive adjustment options such as a variable low-pass filter, subsonic filter, and bass boost, the amplifier can be precisely tuned to the subwoofer being used. High- and low-level inputs allow for easy connection to both factory-installed and aftermarket radios. The integrated USS (Universal Speaker Simulator) technology also ensures compatibility with modern OEM radios, while the wide operating voltage range allows for use even in vehicles with modern electrical systems.
