Are you powering the Pionners with your head unit? I've got the 2 way 6x8's up front, and there is no real bass, but theve got some punch to them... And I'm pretty happy with the overall sound.... Nothing speacial, but for the money, its good.... Of course I'm pushing them with a Rockford Fosgate 400.4 turned way down of course.... The pionneers sounded really good when I still had my Audio Control 4.1 and 3xs Crossover installed..... REAL good......
