Sub box build help
I registered on this forum for one thing, and one thing only. That is to help my friend get his subs into his Intrepid. He's been waiting for someone to come along and build him a sub box for a very long time. He has 2 15" Alpine type R's and he knows it's going to be a very tight fit in his car. I've looked up specs for a box to have 2.9 cubic feet of air inside, which is recommended for these subs. Ideally, he would like 1 ported box that fits both the subs. The dimensions recommended for one box is 19.5" x 16.5" x 20". I've never built a box for subs, but I have built boxes for bass amps. I'm not sure how similar or different they are. I was just wondering if anyone could draw up a box that would fit the trunk with the things I have listed.
Thank you for ANY help whatsoever!
