Do you do everything in life this half ass? Honestly bro how could you think that what you built was qualified to be a subwoofer box. I'm not ripping on you for feeling the need to build a box, you just did it sooooo badly. By the looks of things though I'm guessing you don't care to much about your car, much less what you put in it.lol no, i got a random urge to build a box so i used what i had. there was some plywood leftover from remodeling the bathroom that i managed to use for the base, the rest is from scrapping the other sub boxes.
In the end it's your stuff so have fun
