I don't even know if this is possible. But would anyone know how to make these? The original thread is over on the Skyline forum here: http://www.skylineowners.com/forum/2...-my-z33-2.html . And so far, I can't find out what the measurements are or get in touch with the OP Any opinions

 

measure l x h x w

and make it

 

Use cardboard, build a template and have at it with a table saw, a drill and a jigsaw. 3/4" MDF is your friend. It's easy to work with. You can get all the hardware at your local sound store or on Amazon.

For what it's worth, it's a decent looking solution. It's a bad spot for putting subwoofers though. They'd sound better in the trunk. Also, those spaces desperately need Dynamat.

 

I took your advice and measure it all out. wooden box is just not practical........not for any kind of good sound anyway.....I've got a custom box in the works with my local audio shop and paying next to nothing for it in exchange for some work on his BMW Thanks for the ideas though guys!
