I bought the two for one deal at circuit city a couple days ago to replace my blown mtx 4500's. I blew them hooked up to a swiss audio P.O.S. amp running around 300w rms. I only have one CVR hooked up now but DANG!!!! This thing thumps HARD. I finally have something that hits the lows and gets extremely loud. i'm waiting till I get my zx750.1 amp to hook up the pair but for now the one outdoes my friends black Xplod's and rf325.1 amp. If any of you know of a better amp for around the same price send me a message, I'm new at this and just want something reliable that also has the ability to make my friends jealous.
