[QUOTE="goldfive, post: 7034655, member: 613727"] the sub enclosure was custom made out of wood and fiberglass to fit behind the seats in my two-seater. I did my homework and it **should** have had enough airspace for the minimum requirements of the sub I chose. But I didnt have time to finish the box, so I let an installation place finish it up when they put my whole system in. The installer said he needed to reinforce the walls with dynamat because he thought the fiberglass was too thin. I asked if he filled the box with polyfill, (which the sub manufacturer said to do) and he said he didnt put polyfill in the box because he didnt want it eating up more airspace (which sounded strange to me, because I was under the impression that polyfill makes the sub think the box is bigger, not smaller). So, I can't alter the sub enclosure-- there is simply no room for anything bigger. I probably made a bad choice of a sub, but it's too late to change that too. All's I can really do now is try to compensate with an eq as best as possible. [/QUOTE]
