Figuring out volume for a crazy shaped enclosure

I'm trying to think of ways to get a general volume of my Scosche Tacoma box. I plan on using this box with a much better shallow mount sub than the lame EFX sub it came with, and have exhaustively searched for volume specs with no dice as these boxes are NLA. I'm trying to get some figures so I can purchase a shallow mount sub based on the volume of this particular enclosure. As you can see by the back of the box, it is so convoluted that I have no clue how to get this figured out. Fill it with water and use that to equate the volume? Thanks for any suggestions.

 

Fill it with packing peanuts then measure them.

 

Being it is plastic I guess water would be fine.

 

I guess I'll try the original water idea I had as you all seem to agree as this being a good option. Not real sure if shallow mounts are very critical on enclosure size, but many seem to be requiring around .5cf or so. Thanks for the replies!

 

Yeah, if it's plastic use water.

 

most sealed boxes sound pretty good in whatever the air space is. its when you get into porting the box where everything has to be almost dead on. Size, location of port, and size of port.

 

According to his pics, I would say... sonicelectronix.com

 

I think "NLA" = no longer available.

 

Yep, NLA. I purchased it off Craigslist out of Cali back in November. I have to buy the Alpine amp it came with as a package deal in order for the guy to ship. The sub is a shallow mount Scosche EFX. I just wanted the enclosure as it slips right into the passenger side plastic storage bin which was very appealing to me. I'll put a better quality shallow-mount sub in as soon as I get the volume figured. The box is ABS, but to my surprise is very thick and stout and even has braces that were molded into the box during the extrusion process for rigidity. If it will help you search classifieds, use Scosche TATAC05 which was the model. The front shot I posted is actually a board member's box with a Kenwood Excelon mounted.

 

Based on the size of that enclosure that'd be maybe $180 in M&Ms???


EDIT: I missed how deep the actual speaker area was... upped my bet by $100...

 

This has to be the most awesome response I have ever gotten on the internet! Ever!!!

 

I highly doubt that peanut M&M's pack closer together than sand. The void ratios on sand is nearing a 1/10mm where as i can see between peanut M&Ms, but damn that would be awesome to clean up. Yummy. LOL

Model it in solidworks, get the thickness with a micrometer and calculate its inverted volume?

Use water or something

 

Nope... Pop Rocks... then fill it with water and seal it.

 

I say coke and mentos

 

Go CSI on it. Get a tub larger than the enclosure, cook up some putty like substance - like jello! to fill it with, push the enclosure into it, submerge, measure how high up the jello goes, take that volume and subtract ah, thickness of the enclosure times some sort of assumed area and ah... yeah. Then you can invite the girls over and forget what you were even doing.

 

^^

Even fudging it a bit to guesstimate the difference due to the thickness of the enclosure walls this may produce the best result. You could just do it with water... although jello and inviting girls over to help could add a whole new element to the exercise!
