Tips/Tricks for affixing drivers and plate amps in DIY speakers ... (1 Viewer)

[Mike Lenthol]

I'm currently building a DIY sub and getting closer and closer to the stage of mounting the driver and plate amp to the box, but the problem is with using bolts and nuts to do it. I'm not very fond of screws, as the MDF tends to not hold the screw after a few screw removals, and screws don't allow as much pressure for tightening as bolts do. Not to mention my driver/amp are recessed in 3/4" MDF so using screws is not a good idea right from the beginning, as there is not much for them to grab onto.
The thing that makes me think is how to mount the nut on the 'inside' of the box. I have a few ideas, like maybe cutting out small squares out of MDF, then carving a space in it for the nut, and sandwiching that nut between the two pieces of MDF and gluing it all together, but that's not very effective me thinks so I was wondering are there any 'gadgets' for simplifying what I'm trying to do?

Yep it's called a T-Nut. Get them at any hardware store or Home Depot super store.
