Im in need of help for my current build. Its a 91 Honda Acorrd. Im going to be using a Soundstream XXX15 with a MA Audio HK4000D. Im Using 2 XS Power D3100's in the rear. Since my back seat lays down I want to build a sub foward/port foward style box. I will then seal it off on the top and sides of the trunk opening of where my back seat/trunk meet up. The dimensions I have to work with is 33in wide by 28in deep by 18in tall. Here is a pic to give you a ideal of what im working with. Also added a link to soundstreams website to show all the specs and recomended enclosures.
