I have two planet audio 12 big bangs ported. And this soundstream amp is only 600 watts rms and the amp is huge, about 2 feet long. I dont know why this is, but the amp powers them subs pretty good, and I love it. But you know how it is, nothing is loud enough. The subs are 500 rms a piece and I want more than 600 rms to them, I want the full 1000 rms to them. What is a good amp that will power these babies to their fullest? The subs are dual 2 ohm and I got both the coils wired. My budget will be around 150 to 200.
