well PPI was on the expensive side forever, and when car audio really started becoming mainstream, people did not under stand the high cost of their amplifers and subs, just like SoundStream, Xtant, and Zapco have all put out a lower line, from what I understand PPI sorta was not putting out much for about a year, then the DEI movement and all new amplifers and subs just came out not too long ago, I have seen these subs in a few magazines, but nothing out side of that, cost on ebay has been less than the Orion H2 from what I have seen, personally I have always liked PPI because I was always impressed with their older amplifers, but I am not sure if the DEI presence now means with Viper audio gone, are the Directed and PPI amplifers just the same thing on the same boards with just different names? it would seem like the big coorporation tpe of thing to do, reduce production costs and just rebadge many products, heck GM does it everyday and people get suckered all the time
