What kind of screw should I use to mount subwoofer to MDF enclosure, also what size?

[falconman515]

I know its a basic question but I am not exactly sure what screw is the best screw to buy to mount my 10" subwoofer to the new 3/4" MDF enclosure ... also what length is needed as well?

Thanks so much for the info ... just want to make sure I buy the correct screw to hold the sub tight to the MDF.

Depends on the size of the gasket. 1/2" wood screws would be fine unless gasket protrusion requires more. 3/4 or 1" in that case.

You want super secure, though, drill out a hole for some T-nuts and use machine bolts //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I use 1" pan head coarse thread drywall screws with the holes pre-drilled with a 1/16" bit. I get them in bulk at a local building supplies store. Don't over tighten the screws.

If ur not dealing with a sub over 45lbs use spax screws from home depot ..they have serious bite ..if heavier 1/4 20 tnuts and machine allen bolts

T-nuts are nice until they spin and your sub is stuck in the box!! I use whatever I find lying around. Coarse wood screws work good.

Thats when u take a flathead screwdriver and pry between tge box and sub it will lock the nut in place and allow u to remove it

One option is using a "T-nut" and bolt. You would only need four for a sub and it will not go anywhere. Very secure, but could be considered overkill.

So just a good course drywall screw should be fine?

What length?

 

[TheUnderFighter 10+ year member]

Yup, whatever screw really. If you need to ask, I'm sure it's nothing too wild. 1" is usually fine.

1" inch I think would cause the screw to come out the back side of the wood inside the box ... is that wise to do?

I kinda thought 3/4" would be best since the sub mounting area is not more then 1/8-1/4" I would think ... that way you get about 1/2" bite in the wood without it puncturing through right?

eHow says to use 2" drywall screws?!?!?

So are these screw suppose to go all the way through the wood inside the enclosure???

I plan on using basic drywall or deck screw if possible ... I'm thinking a pan head will also be better ... maybe like the gold or green pan head deck screw or something?

Also what diameter is correct?? #8 or #10 or something???

Like I said ... just wanting to get it right the first time .... I know T-Nuts are recommended by many but I will not be going that route as once this sub is installed it will be there for the next 6 years till I upgrade to a new truck (or the sub blows, but I doubt it ... I don't crank my music like crazy).

Some good concrete type, length and size info would be greatly appreciated. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It really doesn't matter what screw you use, or how much sticks through into the box. I'd go too long before too short personally. I've used 1" coarse thread drywall screws with fine results on 80 pound + subs. Lately I prefer the deck screws with a star bit since it's less likely your screw gun will slip out of a star hole and blow out your surround. Though really if you take care you shouldn't be punching your screw gun through the surround anyway.
