The PPI PCX series again are made by Directed. The same company who bought out Orion. They are decent amps but not comparable to the hand made amps that PPI used to be. The (art series) were one of the best amps made, along with the Orion HCCA's as well. They were both hand crafted in the USA not like now days. The PPI pcx are ok amps I have one in my truck now, but they are very comparable to the kicker, and the JBL.
