mounting sub

[ikasama]

How do you mount your sub so it is on 'air tight'? I have a sealed mdf box, and i think i stripped a few of the screw holes. Is there a better way? any tips greatly appreciated.

peace

well first tip, dont torque it down so hard when you are screwing in.

also pre-drilling your holes will help from stripping out the hole in the future. if you are just straight screwing into it without pre-drilled holes, you will have a better chance of ruining the grip of the screw on the wood.

seal up those stripped holes with some woodpatch, and turn the sub slightly so that you have bare wood to mark holes on, predrill them, and use some good quality wood screws with at least an 8 thickness.

buy some "tee" nuts. They are made for use in wood. They have some spikes that dig into the wood, then there is a machine thread on the inside, and you can just use a regular machine screw, like 10-32 or something. Its hard to describe, do a google search for it.

Do not use "tee" nuts, I found out the hard way! somehow after I had them installed, the threads got screwed up and I couldnt get my subs out. I was able to drill the heads of the bolts off, but I ended up breaking a drill bit and putting a hole in the rubber surround. It's a pretty small hole, but it sucks ***.

I'm in the process of coming up with a new mounting technique.

use a nut and bolt application similar to this - make sure you pre-drill those holes to it fits nice and snug. those "prongs" get pushed into the wood - use light hits with a hammer to get them nice and tight. you might wanna use a drop of epoxy or super glue on the prongs to keep them from vibrating loose from the wood just in case.

yep, those are T-Nuts. perfect if you're ever going to have to remove your subs from enclosure down the line (for whatever) cause it doesnt matter too much if the screw holes strip out...

You could always use the typical drywall screws and coat a lil glue/silicone on them just before you screw them in. dont spill...

otherwise, as long as the baffle hole is not too big and you use a lil weatherstrip you'll be fine.
