FroznBeavrBALLs Posted December 14, 2011 Report Share Posted December 14, 2011 My lil bro wanted me to design a box for his 12" Kicker CompVX for his Convertible Sebring. He wants it to sit as tight into the back of his trunk as possible so he would have some trunk space. On the kicker site it says 1.75cubes MINIMUM ported for that sub. here is what his trunk looks like. http://www.google.com/imgres?q=convertible+sebring+trunk&hl=en&safe=off&sa=X&gbv=2&biw=1159&bih=610&tbm=isch&tbnid=BZy3oESRcSGGjM:&imgrefurl=http://www.hallhyundaielizabethcity.com/used-cars/2004-chrysler-sebring-2004-2dr-convertible-limited-v860514/&docid=VEWU0hXgnmhKHM&imgurl=http://www.hallhyundaielizabethcity.com/Images/Vehicles/2004/Chrysler/Sebring/1C3EL65R94N368911_25_lg.jpg&w=640&h=480&ei=8BHoTtvbOsO3twe9tNnnCQ&zoom=1&iact=hc&vpx=409&vpy=305&dur=1451&hovh=194&hovw=259&tx=157&ty=137&sig=111429034971793159806&page=11&tbnh=117&tbnw=156&start=181&ndsp=18&ved=1t:429,r:8,s:181 I would like the flush it with the front of the step down section because it would look good, but there is only about 1.25 cubes net there. Any suggestions? or should i build it to look good and let it sound like it will. 2 DC 12" lvl 4s 1 DC 1.2k XS Power S3400 big 3 Alll KNU wire Pioneer HU cheapo Legacy coaxes (just for now) http://www.stevemead...n-sentra-build/ Link to comment Share on other sites More sharing options...

AmericanLegend Posted December 14, 2011 Report Share Posted December 14, 2011 Don't build a tiny ported box and expect it to sound loud or deep unless you tune it stupid low and put an ass of power to it. My advice would be to squeeze that extra .5 cubes out of somewhere. Have you thought of fiberglassing the back of the enclosure to the contours of the vehicle?

Sheena Posted December 14, 2011 Report Share Posted December 14, 2011 sealed? or move to an 8" if thats possible either way i doubt he will be satisfied with the outcome. tell him to donate more space or its going to sound bad and be a waste of time. 09 Civic EX KDC-X395 (2) SKAR Audio VVX-12 Skar Audio SK-1500.1 4 cu ft @32 (new box and more port soon) Firing Forward not sealed off Stock 80 Amp Alt Big 3 In 1/0 Knu 2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu DD-1'd 13.8v drop Link to comment Share on other sites More sharing options...
dolarbilz Posted December 14, 2011 Report Share Posted December 14, 2011 Just build it to the best size box they recommmed. install it.once he hears it wont matter after that. Link to comment Share on other sites More sharing options...
FroznBeavrBALLs Posted December 15, 2011 Author Report Share Posted December 15, 2011 well he doesnt like to spend money so he isnt gonna buy a new sub. the specs on the website for it says minimum ported box should be 1.75cubes. Does that include port/sub/bracing displacement. I run DC and they tell you how much space the sub displaces. but Kicker doesnt. I want him to upgrade to something better but he is fine with it. He is a 1 set up and done kind of guy. lol 2 DC 12" lvl 4s 1 DC 1.2k XS Power S3400 big 3 Alll KNU wire Pioneer HU cheapo Legacy coaxes (just for now) http://www.stevemead...n-sentra-build/ Link to comment Share on other sites More sharing options...
Sheena Posted December 16, 2011 Report Share Posted December 16, 2011 i found this on ROE through googling from a guy with 1,200 posts and 118 rep for CVX 12" Displacement. ROE: NET DISPLACEMENT 136.8 in3 Yahoo answers: Displacement: .06 cu.ft Kicker website: http://www.kicker.com/sites/default/files/2010%20CompVX%20e01.pdf and kickers website says 1.75 cubes, thats AFTER all displacements, bracing, and port. i say build a 1.75 cu net ported box and see how it goes. 09 Civic EX KDC-X395 (2) SKAR Audio VVX-12 Skar Audio SK-1500.1 4 cu ft @32 (new box and more port soon) Firing Forward not sealed off Stock 80 Amp Alt Big 3 In 1/0 Knu 2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu DD-1'd 13.8v drop Link to comment Share on other sites More sharing options...

ChrisLun Posted December 16, 2011 Report Share Posted December 16, 2011 Your best best is to go to lowes or hd, buy a angle finder. Get the angle of the back seat and build a wedge enclosure using a 4 in PVC pipe for the port. That's is what I have done in the past and it works perfect 2006 Dodge Charger (2) Kinetic 3800 (1) DC Power 270XP (4) T1-12D4 (1) T2500BDCP (2) T400.4 7.5 cubic ft.
