box - box inside a box design ?
anyone done a box inside a box design......ie: a burp box, inside a large box, open to the cabin, kinda like a cave, sealed off from the back of the car......
I know......try it and let us know!!! haha
i never have, just wondered if u had, in my opinion with a sub up, port back i think there would be rex-like reactions no?
just sayin!!

I don't really see the purpose or any advantages to it. What you'd end up with is basically a walled off situation with hidden sub(s). It'd be cool to see done, but I don't see any advantages to it. I'd imagine getting proper tuning would be a bitch, also if you ever had any problems, getting at the sub(s) and wiring would be a pain.
Edit : Sorry, I took your idea and went a step furthur, but only because it would make sense to. With a uniform shape and size to your trunk, you could, in theory, tune your 'trunk', basically turning it into a bandpass box. Or you could port your 2nd box, if you were going to do it, you might as well do it right. Usually when building a box you don't factor in the fact that your trunk and car in general will change affect your tuning because it is too difficult to calculate, but if you were to build a box around your box, you would have some more control over tuning ability. That's what I meant by tuning it would be a pain in the ***. But if you were just making a burp box anyway, and you were thinking of going that route, you could just turn it into a backwards bandpass box. Use your secondary box as the sealed portion, and the outer box as the ported, with the ports facing into the car. What the effect would be, I have no idea, but it sounds cool, in theory.

thats not what i meant......i meant im gettin all kinds of flex.....and my windows out back are popin open and im losin.......hence my inside out box desing idea!!!
and since my pockets seem empty since my bike build got finished, im goin with either 2 powerbass 4000's, or 2 audiopipe 3000's.....its gonna have to do for now.....
still should see a low 50 fer sure on those!!
