if power is the same, and 2 18's vs 8 15's, and u know what ur doing 8 15's will spank 2 18's.

You're assuming the subs are the same. MTs and BTLs are far superior to CVRs. I've used CVRs and probably gotten louder than anyone else with them but they still were not as loud as my single Nightshade with half the cone area on the same power in the same vehicle.

The MTs have a tiny gap and minimal cooling, I would not use them for daily unless I had some recones handy. The cvrs are cheap, expect to replace them a few times if your giving them good power. As mentioned you will have a hell of a time with the box As well. The btl would be my choice of woofers listed because it will have flexible box potential, reliable, and loud. Although with Preston we put a mmats 4000.1 on each DC lvl 4 xl and sounded great and loud (152.2) so the XL would be my own personal choice with amps and space given

Hope that helps

go with some DC Lvl 4 xl 18's or Lvl 5's ;) the MT's are basically SPL subs but they can be used as daily subs steve used the MT's for daily setup in the civic for a while IMO i dont think u would be alot louder with 8 15's than u would with 2 18's...8 15's would take alot more space than 2 18's would and its all i the build and how much power u give them and look at it this way 8 decent 15's that take up alot of space or 2 beastly 18's that can get just as loud or maybe louder than 8 15's and still have alot of space left over

the only person i wouldnt let build my box would be Ray.

I already have 4-cvr 15"s in a ported box tuned to 27hz powered by a mmats 3500.5.It really pounds hard.I recently purchased another mmats 3500.5,should I get 2 re mt 18"s or 2-fi btl 18"s or 4- more cvr 15"s for a total of 8 15"s.I really do not want to wall it off with the 15"s that why i am asking but I want more bass.I have a 2001 suburban with 4-15s and still have the third row seat,the box or the 4-15s is 15.46 cu.ft with a 120" port 19.25"s long.Can anybody tell me if 2-18"s will work in this amount of airspace.

Thanks to everybody except the person that called me stupid.If you think the questions to stupid for your taste, keep it to yourself.I know about cone area being more,but would it be worth the time,effort, or inconveniance of having a wall with 8-15 or abox with 2-18 bass wise.(is the difference in bass worth the hastle.
