View Full Version : Box build for 2 kicker comps

03-12-2009, 11:02 PM
A buddy of mine is looking to make a box for his two 12" kicker comps the black models. It will be in a trunk in a VW. The specs for sealed are 1.25-3.5 and ported 1.75-2.25 per sub. I never messed with kicker comps. So what would be better ported or sealed and how much airspace after displacement of port if ported is best way.

Hes got around 400-500 watts to play with.

Also if ported is best way to go should go with slot or just go easy way and use a piece of 6" or two 4" pieces of pvc for aero's

Cliffs. two kicker comps black models.
ported or sealed?

id do ported. 4 cubes to 33hz. thats what i had my CVRs in and they did great.

well these are the comps the black ones not the cvr's didnt know if there is much of a difference.

Also will talk to him and see if he wants a low tunning for moving air and vibrations or just higher tunning for loud to the ear and more of a louder notes and not low notes.

Also does it matter if we use two 4" pvc ports and arent flared

Sounds good to me...use a 6" aero port.

ok well these are the black comps, didnt know if it was much difference. I also didnt know if these subs performed best in sealed or ported. If i go ported can i use just two 4" straight non flared pvc ports or 1 6" straight pvc port

go with the single 6" and at least try to round its edges

ok, i figure just go slot since it will result in less port noise.

Then again it will be in a trunk so wouldnt hear port noise anyway right???

true but port noise equals less out put

03-13-2009, 02:54 PM
ok true.

Well then i will just go with slot port

how can i figure out the port area of a slot port i know more about aeros than slots

a 6" equals 28.26 inches of area just convert it to a slot port , say you have 14 inches in inner height it would be a port 2x14

rough estimate:)
