AMI CUSTOMS Posted July 13, 2011 Report Share Posted July 13, 2011 Here is my technique and it works for years now, been doing this on dozens of installs, for subs, I never use tnuts but instead use #10 pan head steel screws you can get a box of like 100 for cheap, I use 1.5 inch long and use that in conjunction with a 1.5 inch or thicker baffle, on some I have reused the same holes over a dozen times with 60 lb woofers. For removable and tunable ports I use tnuts usually 5/16 cuz they are less likely to spin on you and strip out and I use in conjunction with those gorilla glue on the points of the tnut that way those sucker don't move.

For removable and tunable ports I use tnuts usually 5/16 cuz they are less likely to spin on you and strip out and I use in conjunction with those gorilla glue on the points of the tnut that way those sucker don't move. That's pretty much what I use #10 panheads length depending on the MDF thickness. But the question is what about when you remove the subs? You can't just drill a #10 back in there because since it's practically sawdust if your lucky you'll get a tight hold. Which is why a metal ( or hurricane nut ) would come in handy. From what I cam gather the hurricane nuts are easier to use and you get just about the same strength. Mind you that I am not doing a wall holdin an 80+ lb sub. I'm Doing 25lb subs upfiring. But I was really just asking questions to learn a little more..incase someone were to ask me I could pass on the knowledge. But thanks everyone for the input. I did learn a bit!

AMI CUSTOMS Posted July 14, 2011 Report Share Posted July 14, 2011 I have never had a problem with the pan screw going back in and holding fine. I have taken some of my hdc3s in and out over a dozen times easy. Still hold just as strong.

I must be doing something wrong It usually gives a good strong hold the first couple of times and gradually gets weaker. I also use pan head screws to hold the subs in place. But after I remove the subs a few times the holes seem to get much weaker.
