Short and simple the power acoustik 2000.4 is alot louder and alot more crisp being full range class d the ppi still has that same old midrange heavy class a/b sound of the cheaper a/b . The power acoustik is 30 dollars less and from what I've heard id recommend it over the bk 800.4 for sound but the 800.4 for more reliability
