Uhhh neither of those are diamond subs....
IMO pioneer and kenwood subs are mainstream garbage. Pioneer has some of the best source units, and kenwood isn't too far behind, but their subs are left best for boat anchors. Ever wonder why you don't see speakers you can buy at bestbuy winning records? The rest of my system is DA. 2 set of hex components, pair of d6 6" mids, 400.4 amp, 600.1 amp, and currently 2 d3 12 dvc 2's.
Diamond Audio FTW !!
