I just thought I would worn you all about a problem that I have ran into with the Rockford Fosgate P2s. After you use them for a few weeks the dust cover gets stress cracks in it! They claim that it doesn't hurt the sub, just makes it look bad. Thankfully I bought the warrenty on them and the kenwood amp and replaced them all. They sound good just are cheap!

 

I just put a 12" Memphis sub in my wife's P5, and I've been very happy with it so far.
