Which MTX Setup is Better?

Hi, I want to know wich one is the best, 2x 12" MTX Thunder 7500 single voice coil in a Sealed Box or 1x 12" MTX Sledgehammer T9500 Single(T9512D ) Dual Voice Coil 1000W RMS( Ported Box) or 2x MTX Thunder 9500 10" T9510-04 Sealed Box. The first 2 will powerd by an 801D and the 2x Thunder 9500 10" will be powered by an 105D, Pls let me know wich one of the first two is the best, Thanks a lot.

Hi, Thnx for reply me Velocity Motors, Yes the 2 12" Thunder 7500(7512-04)single voice coil subs will be wire Parallel so that the Amp.(801D) will be pushing 800 Watt RMS to them @ 2 Ohm. and the Other is a single Subwoofer Thunder 9500(9512-44) 12" but dual voice coil 1000 Watt RMS in a Sledgehammer (ported box) and the third is 2x 10" Thunder 9500(9510-04) single voice coil 2x 750 Watt RMS wired in parallel i think in a Sealed Box. the first to is most important for me right now because i already have the Thunder 801D Amp. and i want to know which of these two should be better for mi situation. But i want to know if the last should be good if i change my Amp to an Thunder 105D Amp(1500 Watt RMS @ 2Ohm) for them. or is an 10 inch Subwoofer not so good? I have a Toyota Corolla 2001.I have 2x 10" Thunder 7500 single voice coil sealed box in my car right now, it sound great but the bass outside my car is a bit weak because i put sound demping mat in my trunk, and they told me that i have to change the 2 10" for 12" for more air movement, that's why i want to know what should be the best for me. honestly i like 10" subwoofer more than a 12" becuase of less room space, but that's not important more, the important is that it sound loud. and i like the Thunder 9500 series.Thnx a lot.

Hi everyone i'm a bit confused here pls help me to choose wich one of these two. Don't get mad pls. Wich one should be the best, 2 12" MTX Thunder 7500 Svc wired in parallel sealed box powered by an MTX Thunder 801D 800 watt RMS or 2x 10" MTX Thunder 9500 Svc wired in parallel sealed box powered by an 1501D 1500 Watt RMS? in a Toyota Corolla 2001. thanks guy's and please don't get me wrong.
