Id like to build a custom box for my car

 

I am a pretty simple guy. You may have to break it down a little further than that.

 

figure out the size of the box you need, maybe make a cardboard box to the size you need, fill it with packing peanuts. Then get the back side of your box like I did, fill it, figure out the front spot for the sub, empty it of the peanuts, finish the box

 

Nice. That probably works pretty well. Never thought of that.

 

Im done with it, but I dont like it. I thought the fleece would stretch and cover a bit more, but it didnt so I might do it over
