I recently built my own subwoofer box for my car.
First think i need to say is that this box is an overkill for my musical listening habbits. I probably use about 10percent its potential, however combined with the focal component speakers i installed in the front it sounds really good. The sub fills it in nicely in the low end.
I first wanted to see what you guys thought of the box, which is rhino lined if anyone is curious. Second i was hoping to see what other people have done to solve this problem.
