you want something rigid. aluminum or steel sheets work well, but thin masonite or other paneling can be fine - just make sure both sides are covered with deadener to increase mass.

if the hole is larger than my hand, i will add something to cover the hole.

 

my new box project we are putting in a friend of mine's car.

 

looks nice, he should be very happy. good to see you're keeping it tight to the sides.

 

we needed about 3.5 cubes. he wants to still be able to remove his spare so we are removing the floor in the trunk and completely remaking it so he can have a large box and still remove his tire.

 

Cool. I like enclosure designs that allow functionality.

 

just realized that I never posted finished pics of that other box I was working on.





Paint didnt turn out as good as I was hoping but my friend (owner of car and box) did not want to repaint it. I think he was just ready to get it in his car.

 

and the box I am currently sporting.

 

I like the boxes. So much better building your own, they can be much stiffer.

 

I have also never seen a prefab that wasn't "loaded" come with the correct air space either. most prefab twelve boxes I have seen come with 1 cube per sub and the port is about 1 inch wide. That box for the diamonds is 4 cubes (total) with a 3.5" port. I get visible flex in my front windshield, no distortion, and I can still hear my mids and highs clearly.

 

I wanted to share my experience at my first car audio show I ever attended. I was kinda sad I didnt run. I am kinda curious what I could have done.
