I just wanted to get an idea of how many (if any) of you all with 4th gen maximas would be interested in a custum fiberglass sub enclosure. I can make them to fit whatever you may have, the design of the box will obviously depend on the sise and type of woofer used. Anyway, let me know if its something I should do. If there is enough intrest ill make prototype for you to see and try out of your in the So. Cal. area.
