Sub box stacking

[alecwilde]

I remember reading about it a while ago but I forgot the answer. I'm a noob in car audio so please bear with me(most I have ever installed was a 12" 300 watt rms MTX sub in a sealed enclosure in a trunk).

So, could you possibly stack(say 2 boxes each having 3 12" subs) on top of each other? I own a 2003 Limited Edition PT Cruiser. Height is not an issue, but depth is.

Thanks!

there shouldnt be a proble, just make sure each box has the same amount of airspace

It wouldnt be a problem, but IMO you would be much happier with a custom built box made for all the subs, also it will look much better as well, there is a shop near me that sells Diesel Audio, and they do that, they just stack prefab boxes on top of eachother, and to the untrained Bass head may look cool, but to us more exp. bass heads you sorta think these guys should be embarrased, plus I dont even think they know how to make a box. If you build a box to the specs of the sub or have someone build one for you, it will look alot better and perform much better.

Also if it gets to a certain point in height, the subs will tend to not perform as well, as they are in a way choked from the rest of the cabin.

are you talking about pre-fab boxes, stacked? or 1 big box, - 3 subs bottom, 3 subs sealed top?

stacking is a bad idea, falling over, or in an accident, death

and yes, there was a death last year I believe, or the year before where there was a un mounted box, in the back seat of a car, flew fwd, and killed a guy

custom would be way better

Haha I get what your saying. So the height problem was a concern of mine...not sure if it would affect it that much

I was asking if you could possibly do pre-fab boxes. I would have to know the dimensions of a custom box first.

Well you could get some L brackets and bolt the bottom one of then a straight bracket and bolt the top to the bottom one

Brackets may not hold too well if in a wreck, especially if they are holding a tall mass.

Also a custom box is a box built to the dimensions of the space you have available in the vehicle, so if had width depth and height dimensions, you could get a box designed/built for your application.

Yeah I was gonna wait until tomorrow to get the dimensions. I know it's 34" wide not sure bout depth or height.

What if instead of 2 boxes of 3 12's sealed, I put 2 boxes of 2 12's ported. I was thinking about toying with the cheap hifonics.

I could always add an extra support horizontal to the boxes. Say one coming from the seat to the back of both, or 2 to the top

imo go with 3 12s ported in a custom box, subs up port back.

Question is...what kinda sub? It's a PT Cruiser so the port will bounce off the back pretty well and come forward.
