I use to have the DB Drive Platinum 15's and they were great subs for the price. They took rated power and then some. I had them on a Rockford T2000 for a while before I sold them. A friend of mine has the Platinum 12's in his honda being pushed by 2 Memphis ST1000D's and it get's loud and low. Great sub's for the money. I don't really know anything about the amp's though.
I had a db drive amp that my friend was letting me borrow temporarily and the thing gets so hot that you cant even touch it and it feels like its made of plastic. something you would find in the swap shop.
