I just purchased this sub. I replace an older model Alpine type R12. There was nothing wrong with the alpine, but I just wanted to switch things up. I searched through all of the higher end subs that Sonic sells, and I kept coming back to this one. For 144 bucks I thought what the heck, I'll give it a try. I've known of Fosgate for a long time, but I didn't know what I was missing out on! I'm running one of these subs in a 1.20 cubic foot sealed box on a 600 W rms pioneer amp. So far from what I can tell, this sub will take a lot more juice then what I'm feeding it. For one 12 on 600 watts, this sub is hitting pretty hard. I'm thinking of putting my old MTX thunder 6500d on it and seeing how much louder it will get! You will not be disappointed with this sub. Trust me. Only gave it one star for durability because I haven't had it long enough to find out, although it seems pretty tough, especially with an aluminum cone. Oh yeah, and fosgate is an AMERICAN company!
