well i have about 4-5 cubic feet and around 2000 watts which would you pick. Havn't heard near as much about the dp so any additional info on it may help. the dp also cost $100 more so unless its quite a bit louder i'll prolly go with the sx.
an SX won't handle that much power too well, it's rated at 1000w rms so i would go much over like 1200 on one. a dp would do much better. they have a link to their forum on their website http://www.incriminatoraudio.com , they're good guys.
well the dp is only rated at 1200 rms so not much diff and i know the are both very under rated. plus i havn't bought the amp yet i want to choose my sub first. so 2000 is just they most i would probably go with may be more like 1500 //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
from what i hear the SX cannot keep up with the DP. LI maybe, but DP i dont think so. again i dont have any experience with either of these subs. will with the SX soon enough tho, if fedex ever gets it to my **** house.
