i couldnt find any 1/4-20 allen bolts at parts express. going to need 1-3/4 or longer since its double baffled. shouldnt be hard to find somewhere like lowe's right?

so it threads into the wood? can't really tell from the picture, but how beefy are the threads? threads in wood is kind of what i'm trying to get away from going with the bolt.

I like these. They dont tare up the wood like t nuts do.

Ace hardware carries them as well. They also have ones that are screwed into the wood with an allen wrench so you can countersink it deep into the wood.

1/4 x 20 is a fairly thick bolt...probably won't fit through your sub's mounting holes.

You're probably gonna have to go with an 8-32 or maybe a 10-24

Double baffle with the inside piece being baltic birch or any "real" wood gives the screws more to bite into than MDF. Same when using "t" nuts. Seen plenty of HT boxes with a piece of plywood behind the baffle to give them more bite.

haha well i guess luck worked for me. i thought i assed out because i used a scrap peice of 3/4" birch that i got for $5 for my front baffle because i didnt want to buy a whole new sheet of mdf.

does ace carry the "hurricane nuts"

I bolt the subs to the baffle before assembly...I am sol if I need to remove the sub for any reason. Good thing for aeroports, I just stick my arm in their with a ratchet.

I use 1/4 cap head screws with a lock nut....double baffle...it isn't going anywhere.

I liked threaded inserts with my old ssx...

^^^ like that?

im having a hard time grasping what actually holds the sub down. trying to mount a 65lb or so BTL lol

box is going to be built out of trupan. this is how the port and sub are oriented, so getting behind the sub isnt going to be an option, will have to drill the bolt holes using the sub as a template, then mount whatever i go with for threads before putting the sub in.

Those threaded inserts are the way to go...

I used them on this build: http://www.caraudiojunkyard.com/forum/fisher-customs/2040-interchangable-port-box-round-2-a.html

They work great.

BTW, that design looks kind of familiar //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

What wrong with screws? I know for a fact people have screwed down fully loaded 18'' BTLs before with no problem.

because when i screwed down my 12" mag with screws and i hit a nice size dip in the road (underestimated it, the sign said DIP but i just kept rolling) and my car bounced pretty good....my magnum was in my cargo area with screws still attached, stripped from the box lol

although, my friend has had his 15" XXX the same way, and its just as, if not more, heavy than my btl.

i guess its just a precaution, although mine comes more so from the experience i had with the mag.
