surprising.
I purchased one of these for my gf after she heard my system. I was a bit greedy and threw it in my car before she got it so I can give a review. I built a .6 cube net internal enclosure tuned to 34 Hz. I had it hooked up to my bxi 1210 at 4 ohms, giving it around its rms rating.
The sub sounds incredibly clean. Probably as clean as my mag 12. It blends seamlessly with my comps, mainly due to it's extension into the higher frequencies. I was surprised at the range of notes it hit. It never struggled with stuff over 100 Hz, and remained composed down to about 30 hz. After that it rolled off quickly. In terms of spl, its not going to rattle anything loose, but it is certainly adequate for filling in the low end for a lower power install. I would not hesitate to push this past its rated power, IF DONE SO WITH CAUTION. It has taken 400+ watts at times and it has yet to bottom out.
Overall, its a very good sub for what it is meant to do. It's very clean, very punchy, and there's times where it blends so well I forget its there. Alpine has made themselves a very nice little sub here.

Awesome! Go hard!
I bought one, I repeat one of these to put in a custom .5 cubic foot box over the hump in my 2008 silverado crew cab and DANG! This thing sounds like a quality 12" sub. Buy it and stuff it in and be amazed. I'm pushing it with 400watts @ 2ohms and it's not bottoming out.

Alpine SWR843D Product Review
Good 8" sub for the price. Only shortcoming is that it does not reproduce low frequently as well as a larger diameter sub.

Nice
Nice little subs adds good bass to system got two hooked up to a crunch cr2000.1 at two ohms getting around 400watts each and they make my 350z rattle, but I also had 1 10" L5 hooked up to the same amp and sounds similar.

Does what it's supposed to
Just remember that you are buying an 8" subwoofer and you shoud not expect the performance level of a 10" or 12" sub from such a small beast, and you'll love the sound this thing creates. Doesn't go quite as low as I'd like it to, but is amazing for its size.
