use metal brackets n bolt them to the back of your box n the base of ur car but use l brackets but be sure to not hit n e thing u shouldnt with your screws like gas tank n s**t u can get those at home depot or something like that
yea but u take a corner too hard one of these times and ur box gets thrown into the side of ur trunk and knocks somthing loose in the box or knocks the actual box loose, it could fall apart eventually is my point from all that banging around
Hi,I am helping my friend build a subwoofer box for his Mitsubishi Eclipse. He wants it to be lying down and on top of the spare tire storage w/a hindge for easy access to the spare tire and he also wanted it to have a plexiglass top for show. I know there's a way to do this but I've never built a box for car system b4 and I know it's not going to be easy, but would any one of you know any website that I can check out to see how this is done and do how I measure this box? Thanks in advance for you assistance.
