a sealed small box will hit tighter and sharper then a ported or vented box. I found that ported or vented delievers louder deeper bass but not as clean. i had a solo baric l5 10 in the kicker hatch back vented box and it blew my mind but a buddy has one in a sealed box and his is tighter and sharper sounding then mine was. Isnt the cvt rated at 400 rms? On all kicker speakers the sens. is low (like 87 or so on most it think) and it takes more power to get them to sound right...
Another thing, i think the cvts are dual voice coil but not sure, if so check what ohm they are wired in...less ohms the more power getting to the speaker
