Question about calculating volume of spare tire well...

3239 Views 4 Replies 3 Participants Last post by  TheDavel
Besides water, sand, peanuts, and beads... is there any other way or trick to calculate the volume of a spare tire well. ? I have a 2015 Hyundai Sonata for reference.

I'd like to fit 2 kicker L7 10's in there. They require .8 cubic ft. each.

(Yes i did Google and search the forum )

Thanks

Foam packing peanuts should get you within +/- 10%.
Then you can fine tune with polyfill or wood blocks, when the enclosure is done.

Length x width x height / 1728 = magic... It’s all basic math. You can get a really close idea of the size just buy measuring it all out. For example, if it is circle that is 24" x 8" with .75" of material thickness on all sides, you'd be at a volume of 2251.34 which is basically 1.3 cu ft.

Google how to calculate the volume of a cylinder and it will help you out tremendously. If it the shape is closer to a “D” you would use ½” of the calculated cylinders volume and then make a basic L x W x H calculation for the remaining rectangular portion. Then combine the two volumes and you’ll be golden of close enough.

+ or – 10% of the advertised TS parameters in a sealed enclosure is accurate enough. Unless you pull the TS of your woofers, you don’t need to overthink or over complicate a sealed enclosure.

The long and short of it, an overall internal diameter of 22” with a depth of 7.25” will give you 2755.9. 2756 / 1728 = 1.594907 cu ft…. so you’d be pretty spot on for your two L7 10s.
