I got this combo in September and the subs just blew out and it's only February. I'm pretty sure the coils are burnt and i didn't even have it up loud enough for a pop. Please don't buy them, your getting what you pay for and as you see it is like a $700 dollar value! When i went to get them installed the guy who is an expert said Boss is the brand that lies the most about how much power they do. It doesn't really do 4600 watts it wasnt even that loud you could get some mtx terminators or kicker L7's or almost any JL's and still have them so much louder than these!!!
