View Full Version : Questions about building to sub's recommended specs

09-16-2012, 10:58 AM
Hi there,

I am going to be building an enclosure based off the specs and instructions found in Skar's product manual.

I am wondering if by following these directions I'll have a good-to-go box, or if there is further work that needs to be done/further materials to be added. Here are some of my questions

What should I build the box out of? I keep on hearing of Medium Density Fiberboard, but are there better or worse options? Or is MDF the standard

What about the speaker terminal? There is no mention of that in the manual, but won't adding another hole and then filling it with a different material affect the design? Also, is that just as easy as cutting a hole to fit it, and then screwing it in? I supposed I'll have to connect the woofer to the inside of the terminal, but I think I know how to do that.

Can I just leave the box naked in its wood? I'd like to have some material or something so its not just bare wood, but I don't know what's best to use nor how to install it.

Am I supposed to bolt the box to my car? How else does one prevent it from sliding around, or is it supposed to be heavy enough that it wouldn't shift under most circumstances. It'd be nice to not have to bolt it so I can move it when I have more to put in my trunk.

i'll try to answer all your quetion

most boxes i've seen are 3/4 mdf or birch
carpet, paint or truck bed liner spray thing
you do not have to bolt the box it should be heavy enough not to slide around

If you have not made your box there are a lot of box builders here, just post you want a box built and priced it, you might be surprised on how much they will charge and might not be worth it trying to build your own box

If you have a SUV or wagon, attach it securely to the vehicle.

18mm Baltic Birch cabinet grade plywood is the best, IMO. Stronger than 3/4" MDF and a lot lighter material...but there is a downside, it do cost a lot more.

I would anchor it down no matter what vehicle you have.
