Just a review of this fine product made by the great company, MB Quart.
I got two of these subs the other day, I am running them on a SoundStream VGA 800.2 amp with 400rms going to each at 2ohms. These have the greatest sound i've ever heard. They hit really low for 12's and can hit high like 10's. The only drawback is they don't have an insane amount of power, but listening to them at a loud volume while going to work for a 30 min drive hurts the chest. They look really good, totally different than any sub i've seen and are built with some quality engineering.
