While havin my system installed at cartoys, i noticed that they always try and persuade their customers to get the mtx 9500 over the w7. I asked a couple of them why they prefer the 9500 over the w7 so much? They tell me this story of how its handles way more watts and wont overheat as fast. And if u belive this they say it sounds better and bumps way harder. Sometimes i just want to but in when their talkin to a customer who wants mainly spl and say go get a triple x or brahma! But hey what can u expect
