8 Obsidian Audio 18's in an Astro

Well now that he has the subs, i figured i would post this up on here. I built the box a little over a month ago, but he just now got the subs from OA, so he's wiring everything up today and finally getting it playing. I'll post up all the pictures i have of the box build and what it looks like now. He wanted a low end ground pounder, and i gave him just that.

Box specs:

40 cubes NET

560 sq in of port

32 hz tuning FTW!

8 Obsidian Audio 18's

10 Powerware AGM batteries

300 amp alt

2 sets of Focal mids and highs (i have a feeling he's going to need more)

Don't think I've ever seen a setup in an astro that wasn't a wall. Should be interesting. I would have used threaded rod personally, though.

Fast forward to 0:35.

Wanted to keep cost down. Ran stress and strain analysis on this style of bracing and the numbers came out looking good, so i went with the truss style bracing. Some people might comment on a single baffle, but with t-nuts there won't ever be a problem.

Blake (owner) had talked to Hank about his box. We decided since blakes van had a little more room (length wise) and less room width wise, we would do 8 instead of 9.

Blake uploaded some good pictures he took with his Nikon. After he put everything in he said it was turning the van into jelly. The sliding side door looked like it was going to fall off. And the only amp he has in now is 1 AQ 2200! Can't wait until he gets 3 more 2200's and shows those subs some real power. Hopefully we'll get a video in the next day or 2.

Should be nasty

He says it is, even though the subs are only getting about 150-200 watts a piece right now.

If you don't have a video by the wego show in Tulsa next month tell him to swing by and we can get a video.
