what are some good ways to brace a ported box (8 cube) ????

He was concerned about weight so the threaded rod would be a slightly better choice IMO.

I had a 8ft3 box that was 1.5 inch thick on all walls and 3/4 on the floor....I thought I was gonna poop out my guts when I took it out once.....it had the subs in it too...but OMG anyway.....

So I wanna drag race my car but I want 8 15's too...what do you suggest I do.....

I don't think he really knows what he wants other then to say "I got a 15 with 8 cubezzzz....watch my box flex with the beat!!!!"

You can't have a big box without proper bracing!Just brace the fu@k out that shit and don't worry bout the weight.

Well at least he has the right idea of using the FI BTL 18... i think he knows what he wants...but how to make 100lbs of shit fit in a 50 lb bag....or preferrably a 35lb bag....might be the tough part....lol

1) Cut the rod to where it's a few inches longer that the entire external dimension of where you're wanting to brace.

2) Drill two holes for the rod to go through.

3) Put a washer and nut on the inside threads of the rod inside of the box. Tighten them enough so where the rod is tight in the box. Don't over tighten.

4) Put a washer and nut on the outside of the box where the remaining thread is and tighten.

This method is much better than dowels, imo.

This is an 8.5^3 box I did last summer. Double baffle on top for the sub, a few strap braces, and window bracing...

Hope you have a heated garage to build in as it's COLD outside //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

the rods will only brace the enclosure right at the point of penetratin though the enclosure....out to a radius around the rod depending on how thick the material is....it does work well...but not entirely as well as a baffle/lattice type bracing panel would

Yes, but consider this is being done after the fact, so that's really next to impossible to implement now.

Where the H does it say that the box is already done?

I agree. Dowels will have a considerable resonant quality you may want to consider...depending on how long they are.
