[QUOTE="bean, post: 68127, member: 541109"] I didn't respond earlier because I, like Alaxan wasn't sure of your real question....sorry dude. I've made quite a few fiberglass enclosures. It sounds like you are going to have pretty good success....Here are my recommendations.... Yes, use a sound deadening material under the enclosure. (on the car, not the enclosure). MDF tiles are a good idea, but if you are REALLY concerned about weight, lay one or two more layer of fiberglass. Make as much of the top out of MDF (3/4") as you can........ If nothing else, it's easier to finish. Mix your resin a little hotter (add a bit more catalyst) than recommended, it will dry faster. I've also seen resin that never hardened completely. Also, use a fiberglass resin that is designed to be poured in layers. Other wise it will crack and peel apart. I like working with the fiber versus the mat. If the enclosure is super strong, rigid, and most important air tight you probably won't experience any coloration from the box. Those resonant frequencies most likely won't be heard........ Good luck! If you need more, just ask. [/QUOTE]
