Quick Review:

The Kenwood Excelon X450-4 4 channel car amplifier is a unique, but versatile amp. Apart from its one-of-a-kind look, this model offers two different power outputs for the 4 channels (grouped into two). So picture this amp as two separate 2 channel amps on one frame. One amplifier has an output of 60 watts x 2 channels RMS, and the other has an output of 100 watts x 2 channels RMS. This allows for several different configurations of speakers and even subwoofers. Some examples of some possible system setups:

  • Run two front speakers with 60 watts RMS each and two rear speakers with 100 watts RMS each
  • Run two front speakers with 60 watts RMS each and a larger subwoofer with bridged 300 watts RMS
  • Run a set of component speakers in the front with 100 watts RMS and two rear speakers with 60 watts RMS each

The combination possibilities are endless with the Kenwood Excelon X450-4. To top it all off, this amp has a high-tech thermal cooling system that includes automatic temperature sensors with an internal fan to keep it running cool, efficient, and distortion free.
