what's better rockford fostage p1 or kicker comp?

[Gerardo]

I have 2 p1 but I wanna upgrade them so what would be better than P1

 

[random.hero1015]

2 18" Solo X and a Kicker ZX10000.1 Warhorse. It should hit just a bit harder then a P1. . Go with 2 Comps, or CVRs from kicker.

If you are not getting a bigger amp as well, simply dropping in different subs will not make much of a difference....
