Btw, with everybody arguing over brands and power requirements I think you'd be very surprised to hear "500 watts" hit 140's and even 150db. I think you need to research customer support above all when it comes to your amp. It's hard to know what you're getting into and you may even purchase an amazing amp to drive it all....but one mistake and you're done. At that point, how well do they support your product?
Everybody has their opinion but bass is bass. There's nothing magical about amplifying that signal. Just find something that fits your needs.
