Angle of my cars seat back

[giantgloworm 10+ year member]

Hey been a long time that I've been out of school. How do you find the degree of slope on a tri-angle. Working out the angle of my cars seat back to have a box made. Its based on a right angle TA thats 17 1/2" tall and 7 7/8 deep. Can anyone help? Thanks

a protractor

I don't have one, and I can't find my angle finder.

The arctangent of that angle in that triangle is 65.77 degrees

And a quick sketch in AutoCAD confirmed it.... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thanks Ion as for the rest 14 tall, 40wide max, and 10in deep at the top of box. That enough to get me 2 1.25 sealed chanbers?

Should be plenty..... gives me ~1.48cf per side before bracing and sub displacement...

So we've got a little to spare //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ok well I'm for bed 16hrs of work ****. Oh well have to pay for box anyways!! Oh ps double baffle right? So what #'s you hit over the weekend?

 

[IonSQL 10+ year member]

Yeah, double baffle.... here's a quick rendering using translucent materials (the real box will be real wood of course //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif)

Oh also want to mount the subs in a spot that will let me add a 4in Aeroport per side. I have a couple with matching plugs so I can have sealed for everyday and ported if I need to //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif .
