2 18"s...Woah, that would be rediculous...do we even have the airspace without a box???

 

Depending on which subs you use, and whether you go with a sealed or ported enclosure, you're probably looking in the 8-10 cubic feet range. Going with a sealed enclosure means you need less enclosure volume, but for a pure SPL system, it's kind of hard to beat a properly-designed ported enclosure.

 

yea, you cant do sealed with these subs, they will perform like complete butt

the box, surprisingly, is going to be around 15-17 cubes gross, then minus the subs displacment (.5 ft^3 for both) and the displacement for the port/internal bracing.

 

Wow, that is impressive. I did not think we had that kind of room.

 

 

cut the odd side pieces out. most of you will be confused, but im gonna get more done tomorow, and you will understand as the pictures progress, as to why its cut like it is.



9.5* angle



dry mock-up





sorta what im going to do tomorow. the sides will extend out with the side trim, thats why the side pieces are cut like they are.



one of the 18s, i may not even use this, im not sure yet



random pic



glued the sides down

 

Good progress...Much better looking than the first

 

i know!!! hahahha im very happy with it so far

 

test fit

this may give you a better idea how the sides will be, notice they are flowing the contours of the side panels



put the back on

 

 

not bolted down yet.





deleted the rear wiper. that plug will be there until i get a rear back up camera. im selling my Nakamichi head unit, as much as i like it, but i want to get a double din screen with Navigation. ill have to relocate the a/c controls, etc

 

Looks like you learned a lot the first time around. This one is looking good so far. Keep up the good work

 

thanks, i appreciate the kind words

the other one started off good, i just changed too many things, cut stuff, re glued, etc....this one im taking my time on.

 

I know I keeping pushing updates, but keep it nice and slow...much better turn outs come that way.

 

its all good

today ill be adding some pieces to the sides.

 

gasp. is that all sawdust on the car? Better be careful washing that off!!
This one's definitely looking better than the last, though. Hurry up and finish it but don't rush.

 

no, it was raining and thats dirt and crap, i need to wash it down.

 

not much done today...by the time i got home from work it was 5ish, then had to go somewhere at 8 so....

ill do this to the other side tomorow probably.

does it sort of make more sense now as to why the sides are like that?

just to throw this out there, i AM fiberglassing the ENTIRE interior of the box for added strength, and to ensure is 110% air tight.

 

I gotch ya now I thought that was were you were going with it.

 

 

where'd all the rivers of glue go? You;ve left a lot of people with nothing to add to the thread...

Matt

 

Thats pretty intense. I've been watching this thread for a while and that is looking pretty good so far. Can't wait to see the end result.

 

i told you im taking my time on this one

no, seriously, the reason there was so much glue slop on the last one, was becuase i didnt have the little squirt bottle of TiteBond II, i just had the gallon bucket.

needless to say, i bought the 5 dollar squirt bottle

thanks!

 

This box is looking TONS better than Version 1.0

I wish I knew about airspace and all the **** that goes into making a system sound right.

 

my old box is in the back yard full of water from rain
