building my first enclosure, and i just bought some silicon sealant. i saw on crutchfield that they said to use silicon caulk.

same thing, or does it not make a difference? should i go back and get the caulk instead?

also, home depot did not have terminal cups. what stores can they be bought in (radio shack)?

radioshack has em, or order them online, or go to a car audio shop in your town.

i would resin the inside, but the sealant will work well. I would use titebond II to put all of it together and then use the silicon to put into all the edges and corners.

terminal cups = any audio store will have them usually.

Silicone sealant is what you want; we don't make bathrooms on this forum.

I still don't understand why people wast their money on all that. Fiberglass resin is just simply simply a better option

Use resin and it completley seals off the inside and adds strength to the box aswell. Plus it leaves a MUCH smoother finsh on the inside allowing air to travel faster out the box (if ported).........but that's just me

:wow: Fiberglass resin and hardener cost alot more than silicone caulk... Resin alone doesnt add much strength.(if any) :fyi: In reality, square cuts and wood glue should be all you need... but silicone works well to ensure an air tight enclosure.

I don't understand why people don't think it adds stength. Do you have any proof that it doesn't? I'm not doubting you, I just want to understand why you say it doesn't

Where I live, when you buy the resin hardener comes with it and it doesn't cost very much either....like $15 for quite alot

Silicon caulk isn't made to expand and contract.It is more for adhesion.Silicon sealent is flexible.Made to expand and contract with joints.And not those joints either:)But like around windows and doors framed in wood so it can expand with the wood.
I use the sealant.

my boxes dont expand or contract , so i dont see any problems there. sometimes i get a bit messy , but once the sub is mounted , it doesnt matter.

What Ever Ways u do it is fine . I belive in the tecknique where CLAMPING AND GLUEING WORKS WELL. I dnt even use silicon, I just clamp and glue. if u want silicon or resin go ahead ,resin does ad more ridgidity to the box. i can tell u if u clamp the box well use good cuts and lots of wood glue u should be fine unless ur building 10,000 watts in a box. then u need to brace like hell

True :laugh:

titebond III ftmfw.
T3 is an extraordinary waste of money. The advantages between T1 and T2 are legitimate, but T3 has no use in enclosure building. T3 is no better than T2 because of the way MDF is made: it's wood dust. T3 sinks deeper into woodfibers to add more tensile strength, but cannot do so in MDF. It's almost 2x the price and has no benefits. Elmer's Probond and T1/T2 work just fine.

Resin doesn't do too much of anything actually. It doesn't make anything stronger in reality and doesn't really help otherwise. It does seal better than anything elseand when used with mat, it IS a great strengthener. Otherwise, you're just pouring expensive liquid into your box while silicone does the same job for a fraction of the price.

Pour a thin layer of resin on a piece of aluminum foil and let it dry...when it's dry, try to break it. You'll notice that it will be very brittle and easy to break.My point is, I wouldnt trust a little resin for strength. Fiberglass structures get their strength from the fiberglass mat or cloth. It can be used to seal a box, but I'd rather spend $4-5 on caulk.

same ****........caulk is fine,better than silicone IMO not to be confused with
siliconized caulk which is fine too
