ported box suggestions for two 15" CVR

[aaron7114 10+ year member]

My buddy just got two 15" cvrs. They came in a really small sealed box and thats just not gonna work lol. So we are going to build him a new box probably this weekend. I dont have alot of experience with cvrs, i am more of a L5, L7 and CVX guy.

I dont really know what kind of box cvrs like. What is a good size box for them? how much port area? what would you recommend tuning the box to?

Again this is for two 15" Kicker CVRs running off a Rockford Fosgate T800

Thanks

really? 2.5 per not too small? i seen on the kicker website that it said 3 minimum.

2.5 will be fine, min, but you can go as high as 4.5...

so 5 cubes at 34 hz? how much port area would you recommend?

5 is good after port and sub displacement to make it 4.5

I would listen to Polect aka Tracy. He knows kicker, which I am sure he better since he works for them. lol

I have seen this and heard this. 15 sqins per cubic foot is about right. I have done a little testing and this seems to fall in line. Maybe even double it due to useing 2-15's, this still wouldn't be over doing it.
