Installed this in a custom sealed box in my 350z and it sounds great. I had the old, thicker 12" Type R and this sounds just as amazing. I even installed this in the worst location (the compartment behind the driver's side seat in the 350z) and it still sounds awesome. Can't even beat the price anywhere else.

I bought this sub to go in my 08 Tundra. When I started my audio build I initially went with the Rockford P3 10' shallow sub, then upgraded to the P3 12', and finally to this sub. This sound undoubtibly sounds better that both of the previous subs, it will really handle the lows alot better than I expected. And right now I only have and MRP 500 pushing it. I am not even sure I will upgrade the amp it just sounds and pounds so good now. It is a little $ but you get what you pay for, and out of all the shallow subs I have heard this one is the cleanest, tightest, most accurate I have heard.

I bought this sub 6 months ago and put it behind the seat in my Dodge Ram 1500 standard cab truck and it pounds so hard. I would definitely recommend it to anyone who's looking to get a lot of sound and power out of such a thin sub.

It's the slim design of course - fits right under the seat in it's enclosure in my pickup. But I also wanted a sub that provided clear reproduction without being boomy. This Alpine meets its traditional fame for doing just that. I listen to a broad range of genres and this sub is perfect for everything from classical to prog rock.
