old dude Posted May 2, 2011 Report Share Posted May 2, 2011 I just gutted everything in my van and i am ready to start a new box for super street no wall. 2 level 5 18s on 2 vfl 500.1s and 2 ho alts with plenty of batteries. material for new box is sheets of 1 1/2" thick mdf front of box will be 4 1/2" thick. top and bottom sides will have to be 3" thick in order to keep 18" subs below the window line which in my van is 26" i am starting the box at 19CF and will reduce down by adding to the rear wall until I hit the peak on the term lab. so this is going to be my first time in no wall. I dont think I have room for a cage or do I? With my front wall being 4 1/2" thick I already have decent depth for a tune in the forties. a question on that is if my van peaks at 45hz then do i build the box to around 39hz?

ALPINE408 Posted May 2, 2011 Report Share Posted May 2, 2011 no body modifactions in ss nw so where would the cage be inside the box? Quote Have you ever had your woofers blown? Link to comment Share on other sites More sharing options...

mhart Posted May 2, 2011 Report Share Posted May 2, 2011 the cage would be around the box, if your van peaks at 45Hz is that with the no wall box or when it had a wall?
