I picked up a 12" Soundstream Tarantula T5, just powered by a small MTX Monoblock for now for the blazer, got it for dirt cheap, and it out pounds my buddy's pair of 15" DB Drive's with a MBQuart Discus 1500.1, and it hits harder, has better overall range. I was gonna amp the crap out of it and see what it would do, but now that the baby's almost here, I am most likely gonna have to take it out and throw it in the GP.
