ok i am probably gonna get the 6000 series regardless of what anyone says but i still want to know if besides being able o take more power and being louder i guess, is the 8000 series really much better in quality. cuz since mtx is a really good sub company, the 6000 sould still be really good. just wanted to know any opinions people have. also i was gona get a profile cl600m to push these cuz its cheap and people have said it will work fine and be reliable. do u think that is true and if not can u suggest another amp that is really good for the price. thanks
