Summary: I have 4 of them in a 4.5 cupid ft seal box being push by a t1500.1bdcp and man they pound and ask for more these babies are a huge step up from the grey ones the 2011 ones are made like the power serous and sounds a like them great bang for ur buck
Pros: Waayy better than the 2010 ones the new can really take a pounding to and never gets hot only warm
Cons: They are great but spend the extra money for the power series
Conclusion: I love the p3 line from rockford but the pvc boot is not a good add on, yea it looks good if u invert the sub but it also can cause more heat build up. Other than that i think it solid but I don't know if these are as good/reliable as tje 500 rms older models (light grey cone) those could take some power for long periods.
Conclusion: Man, I had the older versions before, and they burnt out on me. So, Sonic gave me credit and a discount on these, and man they hit stupid hard. I just need a better amp than the Boss amp I have, 'cause I know they have more potential. I am straight with these 12"s. Oh yeah, make sure you have a strong box, 'cause they will break your woofer box apart. That's how hard they hit in a 2003 nissan max.

Conclusion: Have it wired to 1 ohm. Running a rockford 500-1bd to it with 8 awg speaker wire. Hits hard! It's still being broken in. Great bang for the buck, have it in the 2.8 cubic foot wedge ported box they sell on this site, nice sub box.
Conclusion: Just hooked it up today to my old school Power1000bd @ 4 ohms. I got roughly 520W RMS going to it (when amp is all the way up). It's halfway and this thing hitsss. It surprised the hell outta me. Upgraded from hx2's big difference recommended to everyone who loves clean tight bass.

Conclusion: These subwoofers are so amazing when compared to the previous models. I have a single 12" in a 4.0 cu.ft. custom box that is tuned to 35Hz. As a result of the large port area, the sub gives an extremely low, deep, clean bass! It absolutely bumps even when underpowered. So as far as spl goes, well. You figure it out.
Conclusion: I have owned two of these now, as an upgrade from my old cheap subs. The first one blew after about a month. After some research into the box, it appeared that, due to some moisture in the box, it was possible that was the cause. So we bought another, made a custom box (what was recommended by RF, by the way) and made sure everything was sealed properly so this wouldn't happen again. I owned the sub for about 2 months. No issues.
