Summary: I'm very disappointed. The subwoofer I received was manufactured in 2011, that's 4 years old. I have a Rockford Fosgate R500X1D prime amp (amazing) pushing it, I'm running the coils parallel so it puts a 2ohm load on the amp. It blew one of the coils in a weeks time and everything wasn't even turned up all the way. I'm very disappointed.
Summary: Got the P3 to fit in an MTX ThunderForm enclosure for my new Mustang because the MTX sub at the same power level was too deep for the enclosure. The sound is great and it looks awesome. Matched with an Alpine PDX-V9. They seem a good pair.
Summary: Was an extreme upgrade from two JL Audios 8's, these subwoofers (have two inside a chevy tahoe) and boy do they bump. I have only one rockford fosgate p1000 amp backing these babies up but will soon have another to wire each sub to its own amp. The price is also perfect trust me invest in something that wil last you will not regret these monsters!
Hardest hitting longest lasting 12s at a price that wont break the bank !!

Summary: I bought a pair of these because I Have Purchased several Rockford Fosgate products in the past Including 2 P312D4 2005 Model 1000 watt and have always been pleased with The performance . . I have absolutely no complaints about any RF product Especially these Sub Woofers, They absolutely Pound . . They are quite an improvement over RF's previous model P3 12s these have about half the weight as previous p3 12s but all the performance . . .
