I am building my own box for the first time, and although I haven't completed the design I was going to just build it from specs on the DD site, and I realized that the vent is on the side of the box whereas the speaker is on the front, if this is a good idea how should I place the speaker in the rear of my explorer? If this isn't a good idea can someone suggest the best way to put it so I get the most bass out of it? Thanks
