Got room for 4 18's?


Recommended Posts

so just for shits and giggles i'm gonna attempt to design a box for 4 18's. going all out and doing a removable port too.

i don't own an SUV, so i really don't know what kind of dimensions i'd have to work with. so if you have a vehicle, like a tahoe, that has the room for 4 18's (without doing a wall) please post the dimensions here.

also, what are some good tuning frequencies? one for daily and one for competing.

thanks all!

some cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches!

My Yukon is 49 wide 22 high to window line cam go a lot higher tho, and if your doin port back you can probably do about 35 to 40 deep if I remember correctly.

blazer is 39 wide, 30 deep, and 30 tall behind back seats, 4 18s is a ton of space i would say in anything other than a truck (blowthrough), or suv you would 100% have to wall.

running the numbers it looks like 4 18's would be a tight fit. i'll post numbers here in just a sec so i can be sure i'm doing it right.

so say i did 4 15 n2's. would 1.5 inch wood thickness be appropriate? or is that overkill?

I think that the numbers look good, and i would say that 1.5" thick would be approriate, but definitley no overkill at all.

EDIT: Maybe a wink more port area. But as it is it is within range.

should i make them the same height or should they be staggered like in the picture?

That would be pretty strong just use your glue wisely, and also you might wanna glass the interior seams just to ensure your structural rigidity.
