Woofer Mounting Screws

Do i drill a hole the size of the piece with the teeth or what?

the nut (with the teeth on it) goes on the back of the hole. the bolt goes thru the speaker hole, thru the hole in the wood, and into the threads on the other side. the teeth sink into the wood and hold the nut on the back, and they are 100% removeable so if you need to take the speaker out, the little "nuts" with the teeth say in the wood, and the bolts come out very easy.
its actually quite simple ddue.

x2 but with a little more 'bite' on the t-nut. I screw all of mine in w/o a sub first and epoxy the t-nuts in place. Ain't comin' out, never.

should hit it in with a hammer before its impossible to do so, they DO fall out of MDF quite easily if all you do is screw them in

not the entire diameter of the screw. just the same size (or a little smaller) as the central shaft of the screw.

If you're using t-nuts, drill it the size of the bolt.

yeah, predrilling will reduce the odds of splitting the wood.

story of my love life....lol......j/k

ya useing bolts and nuts works too..those are a pain in the *** if u need to take ur sub out...

the thingy he was showing you in the pics is your best bet....you need a not fulyl contructed box so u can attach the piece on the back and make work right...if the box is already made........well shit i dunno.......

Why would the box have to be fully made? The thing is big enough to get a full swing from a hammer in there, lmao.

Mounting and hammering t-nuts all depends on WHEN you cut your circle.

IF you epoxy them in, you CAN mount them teeth UP. I chose to on a couple that the holes were a little too close for comfort to the cutout.

Epoxy on the t-nuts makes for easy removal, the t-nuts don't come out. Wood glue might work too, I KNOW epoxy does.

just get a little 2 part epoxy glue. drill your holes according to the speaker holes. (the hole should be the size of the shaft on the "tnut" so it can slide inot that hole from behind (inside the box)

then put a little epoxy around where the teeth are, insert it into the hole you drilled (with NO subwoofer in place) insert the bolt into the other side and tighten it all the way (might wanna use a washer beneath the head of the bolt so it dosn eat up the wood round there)

wait till the epoxy dries (few hours prolly) then remove the bolt and washer, put the sub in place, and insert the bolts down and your done. a bit more effort, but in the end its WELL worth it. here is a diagram.

Ohh, and what size should i use? In ur pic you have 3/8" screw, but that is a pretty big screw.
