Well after reading that in another thread I thought maybe a 'mini-wall' would be the way to go in my sedan. Has anyone had any experience with mini-walls? Just the free-air guys i'm guessing. Anyone have some SPL scores with a mini-wall in their car? Would a mini-wall put you in SS?

Done properly with plenty of fibreglass, I don't want cancelation ruining my efforts which seems to plague systems that fire forwards.

I wanna try a mini-wall but I also wanna try loading off the bootlid like Phil highly commends. Although loading off the lid doesn't leave much box depth for a big enough port. A mini-wall would allow for about 250L if the spare tyre well was to be glassed aswell... very appealing.

a mini wall will probably work better when you need to use a large enclosure

with subs suited to smaller enclosures, facing up in the wheel well may be better

So for my little Alpines give loading off the bootlid first? I could only get probably 200L that way.

thats plenty..

remember that a bigger box doesn't automatically mean more SPL

Also wouldn't fibreglassing my tyrewell put me into SS due to the removal of the OEM boot trim? And fibreglassing of the bootlid. How would someone fibreglass a mini-wall and still stay in Street?

I'm not sure about the boot lid, but the fibreglass should be legal, as it is part of the enclosure.. you could still maybe fibreglass with the carpet still there

I doubt anyone will be too anal about those rules since your car is a sedan anyway..

if in doubt, you could ask in the dBDrag forum..

couldn't u fibre glass the whole boot coated in fibre glass? maybe put down mesh first but make a huge fibre glass box.

Like if u inflatted a huge ballon in your boot that is like the enclosure, so when u open the boot lid u see just fibre glass?

and then have a front baffle of MDF acting as a miniwall? with the big ballon joining that mdf baffle?

that would give you about 350 litres if done perfectly. You could use stiff mesh, start at the back seats and work your way to the back of the boot finally sealing off the box where the lid is.

U'll have to do multiple layers at a time and would take a couple weeks to make, but that would get ya 150db. And the two 12's should fit no worries on the diff pointing forward.

Interesting idea... I don't know about the structural integrity of such a design.... I think a bit more wood would give me piece of mind.... and I don't think I really need 350L. I was scoping my car out the other day and a mini-wall is soooooooooooo much work, I got over the idea pretty quickly after the inspection.
