Excellent Product!! And Definatly a great value

March 22, 2005

The Kenwood KAC-8401 is a well balanced AMP with the built in Fan there is no worry of overheating at high volume levels. The built in crossover allows you to fine tune your speakers to the frequency range you want. This amp offers lots of extra power, I am using it to power 4 Kenwood eXcelon componant 6 1/2 Speakers, Using the amp at 2 Ohm to get its maximum output.
