Well here is the sub box im going to attempt to make for my 97 F150 single cab. im putting a kicker shallow mount CVT 10in in it. Hopefully it all works out.

i got bored and decided to draw something out. lol ill post pics tommorow when its all done. If anyone has any tricks on how to build one, please post them because this is my first one

 

just be sure to use mdf (preferably 3/4), and build the box to the sub's specs for airspace... also be sure to seal the crap out of it with liquid nails. i prefer to use a nail gun...i got a cheapy one at harbor freight and it works well... other than that, just be very precise on your cuts...if you have a table saw, that would be easiest as well.

 

Seal it with resin!!!!!!!!!!!!!

 

Thanks guys! I bought the MDF wood last night at lowes. I also picked up some liquid nail and some L brackets to help the keep the box secure. Are the L brackets okay to use?

 

Yes. If using screws long enough to go through the box then pre-drill, put some silicone or liquid nails in it, then screw in.

I try to use brackets along the edges, making sure not to go into the box.

 

l brackets are fine but i believe cutting a triangle in 90s is better and more rigid

 

you do not seal anything with resin, resin does not make a good sealant at all, you resin it to add rigidity to the wood, seal it with liquid nails is what i do and then resin on the inside and outside of the box

 

Also your demensions/calculations appear to be outside. Remember that each of those will be 3/4" less if you are using 3/4" MDF, 1/2'' if using 1/2'' MDF, etc

 

A good calculation system to use can be found here:

Also make sure you consider the sub displacement which would take away form your overall air space.

 

I have always used liquid nails for my enclosures. Just be sure to use lots of screws too. I have seen boxes blown apart where the liquid nails got brittle.
