Every time I try to find the dimensions of this enclosure, I get a different number. This is the enclosure I have in my car. The first drawing is the box and the second is the spare tire well; which is part on the enclosure. All number on the drawing are internal, and yes I am using 3/4". The smaller box on the left side of the larger box is for the amps and must be subtracted. Let me show you the most recent numbers I got and how I got it and see if anybody agrees, disagrees, or what ever:

Bottom:
4 x 28.5 x 33.5 / 1728 = 2.21
top:
8.75 x 28.5 x 33.5 / 2 / 1728 = 2.42
amp:
4 x 33.5 x 11.25 / 1728 = .87
Tire well-1/2 circle:
[(3.14 x 13^) / 2] x 7 / 1728 = 1.07
Tire well-square:
26 x 17 x 7 / 1728 = 1.79
total box:
2.21 + 2.42 - .87 = 3.76
total tire well:
1.07 + 1.79 = 2.86
Grand total:
3.76 + 2.86 = 6.62

Well, I see that 40 some odd people have looked at this thread and nobody wants to take a shot at it? Come on....

I kinda need to know for my new project.

I get the same thing man

main enclosure - 4.63cuft
Amp rack - .87

Total minus amp rack 3.76 cuft

Tire well - 1.07 + 1.79 = 2.86 cuft

For a grand total of 7.49

When you subtract the amp rack
7.49 - .87 = 6.62 cuft

So yep I get the same thing :)

Too funny.

I have gotten all sorts of numbers but got this one a few times and just needed some to check it.

Thanks.

It's the box I've always had, just never drew it out. I knew it was going to be about 6' though.

My B15 is on it's way ;)

Ya know, if the whole box is gonna be fiberglassed, I don't know why so many think of peanuts, etc, to get accurate info. Fiberglass would be waterproof (some outdoor sinks are fiberglass) so I say fill it up with water, measure how much it can hold in there, you'll get a more accurate reading than packing peanuts... :)

Water works great to figure volume. It's just not an option sometimes. :)

Water is not an option here. I would not be able to get it out. (The enclosure is built into the car, hence the spare tire well.) I never really thought of filling it up with anything...I don't have enough "anything" to fill it with.

Paikiah, where did you get the idea I was going to fiberglass it? I didn't let that out yet....did I? ;)

I think he just assumed considering your using the spare tire well. It would be a pain to build out of mdf :)

Right on...

A tirewell enclosure made out of MDF, with round corners is not seen everyday. Seeing all your previous installs that you did by yousrelf, I DO suspect that you might contemplate glassing. :)

Well, again, that water thing to measure volume, if you COULD remove the box, yeah, it'd be a far more accurate way of measuring volume than to use packing peanuts. :)

If you have the ability to get a hold of a shop vac then what you could do is just pump it out that way, then take a towel to wipe up the majority left, and then use a hair dryer to finish it off. Just a thought, it would allow you to do fill the enclosure in the car, plus you could measure it after you vac the water out. Might not be as accurate as taking out the enclosure, but good enough for government work.

I would hit you up on aim, but I hardly ever see on in the mornings anymore. I plan on going to that show...hopefully with my new toy installed. It got shipped out on Friday. I picked up a new table saw and a roto-zip yesterday and I'm going to get some fiberglass supplies and some ABS plastic today. I'll start on the enclosure this week and hopefully be making some noise by the time the 17th rolls around.

Let's talk before then, maybe you can come down during the install and check things out. ;)
