Most people use T nuts to create a threaded insert. Just drill out a hole big enough for the T nut to fit in and then press it in the hole from the opposite side. Then use the bolt you bought that has the same thread design as the T nut to fasten the sub to it.

Most people use the screw to help "pull" the T nut into it's hole/final resting position.

Here is a pic of what i'm talking about. You can get them at lowes in the fastener section. They have tons to choose from.

Yeah, that's how you should do it. You can piece together the same exact kit with stuff from Lowes like I was talking about. If the shipping is free that kit would be worth it if you can wait for the mail. If you have to pay shipping then it will be more expensive.

threaded inserts worked great in my case. you drill a pilot hole, then thread them into it with an allen. mine are 1/4-20. it's a pretty heavy sub though.

t-nuts tend to strip out, hurricane nuts are a bit better, but threaded inserts seem to be the best way to go. how heavy of a sub are you talking?

I might have to try those fastners next time. I usually just use whatever comes with the sub, mixed with the wood screws I already have.

How did you install the the threaded inserts? Not much room for error with those.

The sub ways bout 50-55lbs.What do you mean they strip out?The inside thred or the outside prongs?

I used t-nuts on my last install and they seem to work fine. only problem is its hard to keep the back but in place after you put the speaker in...

ie: when u try to push the bolt through to screw it in sometimes it will push out the nut if its not in there tight enough.

I was thinking about that.Thought i'd put some resin on it to hold it in place.Or counter sink it just a bit so it fits down in the hole thightly.

i dont mean the metal itself tends to strip out. the spikes tend to tear through the wood and you're left with unattractive options to get the sub back out.
