Conclusion: I have this sub, and it is amazing!!!! I am currently under powering this sub with a US Amps Merlin MD1 1200. It only gives me 600 rms @ 2 ohms, but i have to say that it still bangs!!!! Currently changing my stereo and am leaning toward the Hifonics hfi 1500d. This should push the sub nicely. I ordered a new larger box from Sonic and waiting on it to arrive. Ordered my Hifonics hfi 55.4 today and the big boy will be will be ordered soon.
Conclusion: I have this sub with a kenwood KAC-9105D amp 900w rms at 2 ohms. I've had it for a month now, and just now the sub is starting to break in and is sounding better every day. I was worried about the distortion at first but it seems to be clearing up...I wonder if anyone else has had issues with this. It seems as though it shouldn't waffle or distort being 1000w rms and 3000 peak. But it truly sounds a lot better now than at first maybe it was just break in period.
Conclusion: I've been running this sub for about 6 months and I couldn't be happier with it! People always assume I am running two 12's or something and are amazed when I pop the trunk and they see one lone 10 inch sub! Plenty of punch and hits the lows very nicely! I absolutely love Alpine products and would recommend them to anyone!
Conclusion: Seriously though, if you bought a different sub then you bought the wrong sub. This is by far the best sub on the market today for a 10". I only have a Rockford Fosgate t500.1bdcp and running it at full for hours everyday. People ask me if I have two 12"s. Haha yeah it's only "a" ten. At half power. From one audiophile to any other buy this first and you won't regret it. I only wish I knew more about audio systems when I was first buying 3 years ago.
Conclusion: I have a Rockford Fosgate T1500.1bd hooked up to my Alpine Type X 10 and it is wired to 2 ohms around 1200 watts and play at 3/4 volume for 30-40 min a day and the Alpine type x takes it with no problem and no voice coil heat up odors at all I will eventually get a second type x for the 1 ohm side of my t1500.1 I would recommend this sub if you like it loud.
