In most cases a quick glance at one of the sides will tell you the quality of the wood. How ever this is not always the case.

Most common when cutting wood. This is a look from the outside of a tree.

Here is a piece of wood already cut.

It is physically impossible. Plywood is a laminant. The center ply could have a void the size of a dinner plate and you would never know until you cut it into.

I found the 2' x 2' to be better grade then the 4 x 8 sheets at Home depot.

This.

I bought a sheet that looked great on the outside and knocking across it sounded good. But I made a cut and it looked like someone took buckshot to the side of it.

<p>you'll be fine with whatever you use.  as long as you have decent bracing to minimize flexing the vehicle environment will hide any issues that would be due to wood density.  The noise floor is very high in a vehicle.  i have test boxes built from floor substrate (3/4 pine) and there is not ant audible differences from the 13 plt birch boxes I have.  </p>

Weight has never been a factor for me in choosing a material, cleanliness and ease of use however trumps things.  Saving 5lbs on a 50lb enclosure really isn't so beneficial.  

 

Do remember as well that the only effective acoustic barriers are mass.  Removing it is not always a great idea...

I ended up buying the HD birch hardwood. I just completed the box and it is wayyyyyyyyyy easier to work with than mdf. Picking up the box I can tell it is A LOT lighter than what the box would feel like if it was mdf. I think from now on I will be using this type of wood.

Also the guy at mdf was saying that he thinks the birch would be stronger than mdf. He was also told me some people always come in and get particle board. He says they're a shop or something because its a few guys who have custom shirts on haha he keeps telling them particle board is shit for sub boxes! Go figure it's an audio shop haha

The test box I sent Pat for my 15 was built from the 5 or 7 ply hardwood stuff from home depot.  Their "birch" plywood.  It was 39 x 20 x 20 with a triple layer baffle and weighed 91 pounds at FedEx
