So right now I have a single psi 15 in a 4.7 cubic ft box and that's as big as I can go the sub recommendation is from 3.5 to 6 I think. I have another subwoofer sitting collecting dust and would love to install it but two 15s in such a tiny box I don't think is a good idea anyone got thought on this?
