i've heard good things about them but have no experience with them nor PG. If your not looking to really spend to much money that sub would be happy with a Hifonics amp. They pretty much do rated power. Some people say they do just under and some say their underrated. If you wanna spend the money for a sundown, which IDK how much they are, then do it. I would stick with an eclipse HU IMO and if you were happy with the ti12 stick with it. Now about mids and highs...this is one of the most opinionated part i think. I was happy with my eclipse's and am happy with my mb quarts. If your wanting louder, cleaner, and crisper than go with a pair or CDT, Focal, MB Quart, or Rainbows.
