I am fixing to do a build in my 2002 Acura RSX-S.  I have everything bought except for the sub.  My other equipment is Alpine 9887 Hertz ML280 tweets Hertz MLK 165 mids Audison 5.1k 5 channel.   I want to run a ported box.  At 4 ohms the sub should see circa 750 watts.  At 2 ohms it should see circa 1000.   Does TC Sounds, Audiopulse, or SoundSplinter make a sub that would pair up well with the sub channel?  I would really love to have one with the high roll surround.  I tried doing some searches but came up with tons of dead links and almost no driver specs.  Any information would be helpful.  If I can't find one of these subs to fit the bill I will just go with a 12w7.  Thanks again for your time
