4 sub sonotube/box

Ok so here is my idea, shoot me down if its stupid help me out if you think its got value. Im thinking of trying to mount 4 subs in one box, not uncommon on its own, but the second part is the catch. I want to mount the subs all on the four sides of a cube then use sonotube on top of the cube to make up the rest of the volume. would the odd shape cause problems? a 3in x 11.25in port is recommended, would I just put in 4 ports of that size?   The reason for the crazy design is that I plan to put it in the back of my 2003 Yukon and don't want to totally eat the cargo space, so I figure if I build the volume vertically and save footprint it might work out.

Personally I think fiberglass is already thinking outside the box as it is. Sub size? Denali type? Building plans? Creative idea, but they make lousy bass tubes for single speakers, let alone 4.This is what I do for FUN!

Im not totally sure yet but the subs will most likely be 12s. Its a 2003 GMC Yukon with factory Bose system. Im just looking for a way to make the box take up as little footprint as possible so I can still use the cargo area.

Another detail, im looking at pushin around 1000watts

Gotcha.....You can fit 4 12's in a box that's 13.5" deep. Which only takes the first foot behind the rear seats, then you'd have whats left behind that for cargo. A raised 3" floor for amps is a nice look and easy to do. 1000w of high quality power is probably the lowest amount I'd go for 4 single voice coil subs.This is what I do for FUN!

If using fiberglass just put two under the second seat. Or make a box that can be mounted from the ceiling those always look cool and also take care of your footprint issueRyan Younger

You've seen boxes mounted to the ceiling? I must be getting old!This is what I do for FUN!

you would definitely need to make some sort of support brace

seems like if I mounted it to the ceiling I would need to basically put like a roll cage in to hold it if you try to hang 60lbs min of box+speakers from the ceiling and blast 1000watts something is going to go wrong

I've just seen it done in magazines. So I threw the idea out there. You were looking for a small footprint so I figured no footprint would be better lolRyan Younger
