Just a quick one...
when people make their fiberglass enclosures, are you using the initial MDF, fleece and resin part as the install? or do you make a mold of the MDF/fleece/resin part?
thanks

Depends on yourself really, makes no difference in the end, all you need to do is make an airtight box that's strong enough to house the sub and work under its pressures!!
The perfect way to create good fiberglass is to make a model of what you want to create out of something... ideally automotive clay or a high dense foam.
Or if you cant get hold of such materials, as you said use MDF, fabric and fiberglass to make a ruff encosure, body fill it and sand it. Then once your happy with the shape/finish make a mold and layer up your fiberglass within that, crack the mold open and jobs a gudden. Problem being with that is it's an extreamly long process to create a sub enclosure!! The only real advantage you would achieve is 'saved weight' as you loose the extra MDF, fabric and body filler.
Personally whenever I've done fiberglass in the past I've made a 'what I want to create' out of automotive clay, cast a plaster female mold from that and then produced the final fiberglass from that. Its a long process but it ensures everything is perfect and you barely have to touch up the fiberglass once its out the mold, a quick sand, fill a few air holes and its ready for paint! Also if you good with the shut lines on the female mold to you can then create as many copies as you like!

The main reasons for making a mold of an enclosure plug would be to reproduce multiply copies of the enclosure and as stated above to save weight. If you are just making a part for yourself, it will be much quicker and far less costly to just make a one off part.
