why do u need it stronger?

IF you seriously need to attempt to reinforce with fiberglass.. then u braced it wrong.

The point of resin-ing alone for car audio is strictly for competition purposes, never for daily driving.

Also, even then, i compete and i do not resin either.

I could if i wanted a coupel to a few tenths on the meter but for all that work over and over and over and over and over again...

brushing and sanding brushing and sanding brushing and sanding...

I'm sure i can find other ways to increase a few tenths.

why??

MDF is glue and powder. Getting it "wet" doesn't do anything but make it more brittle. Resin on its own has no strength anyways as it is all in the glass fibers.

The point of resin-ing alone for car audio is strictly for competition purposes, never for daily driving.

And it also isn't to increase strength.

If pouring resin inside an enclosure isn't for strength than what is for?

Smoother interior, better airflow. If done right, you can generally gain a tenth or so on a TL. Not really worth it unless doing serious competing and need that little extra :ughdunno:

so, i am looking for something that reinforces the edges, because i dont have a table saw, so i used the circular saw and straight edges and clamps, and as hard as i tried to do it, some edges are crooked,

like in that, what can i use, alot of wood glue??? extra silicone??

and thanks for clearing up on the resin

Are there gaps large enough you can see light through? Is it air tight?

Really depends how straight / crooked the edges are. Silicone and wood glue can help, but only so far...

Got any pictures?

alot of times I see guys on here recommend using saw dust and wood glue to fill in some gaps... not sure how big but hopefully you aren't off by more than 1/8 of an inch or so....

Mix together wood glue and sawdust to a putty consistency and spread it on all corners and joints, let it dry and you are done, enclosure sealed.

Anytime I've had a cut off more than 1/8" I've scrapped it and cut it again. It's just too hard to do anything about more of a gap than that and make it reliable and trustworthy IMO, but that's just the way I do it and without a table saw too. All you need to make good straight cuts is a circular saw guide, a couple of good straight edge rulers (one long, one short) and a combination square. Those 3 extra tools, along with some patience and good consistency in the way you measure and cut will net great results. My experience has been that the only thing a table saw is actually good for is cutting angles without spending quite a few dollars on a very nice unit that has a good stable fence and is really built well.

wow thanks, that really worked, just waiting for it to dry to sand it down and apply the silicone, i took pictures because i wanted to start a build log, but it was my first box i made, and it will come out alil sh!ty, but it will be bigger than my current box, and ofcourse more port area

Buy some 1/2 or 3/4 corner molding and woodglue it to all your interior corners

also would filling it up with body filler work, or wood filler???

You need structure, not fill.

What I did when I built a box with a radial arm saw that I adjusted with a non-square framing square. Of course that was circa 1988, lol.
