For the most part, a tight fit that is glued together is as strong or stronger than the wood itself.
The nails are there to speed up assembly time and to hold the box together as the glue dries. Same goes for screws.
If you see how they build furniture in a wood shop, there is alot of glue being used versus nails/glue. Lots of biscuit joints, but joints, that have little if any hardware that can rust or loosen up.
If you have clamps (most people don't, where else would you need a clamp with a 36"+ span in a car audio shop), no need for nails really except to tack stuff together.

honestly, any type of wood glue would work, even some paper glue will work (yes it will). any type of screws work as long as they all the wood. and any type of silicone material will work as well.......but i dont know why ppl use it unless they need a super tight spl box.

Nails won't apply the pressure required while the glue is curing...I always use low root(coarse threads) 1 3/4" wood screws, spaced every 4" with a generous bead of carpenter's glue. Tighten all screws 1/2 turn before they strip!!
Any boxes I've had to take apart, the wood spits before the glue joint.

I guess if the glue squishes out it's OK. I've used screws since 1990, when I tried the nail thing.....faster for sure, but I never trusted the seal as much.
Plus screws can be remove if there's any cutting or routering to be done later.

Well, the PL9000 worked great. Put it on like wood glue then clamped it all together, never bothered with nails or screws. It seemed to fill the little gaps from me not getting it 100% sqaure too, which was nice.
It's taken a decent pounding over the last 2 days and seems to be holding together so it should hold long enough for me to get my other box built.
