one of the easyest ways i have found to do console is to make your deck/top of console from wood with wire to prop it it to the height you like once you have it were you like it and ect if your going with metal use duct tape between the sides of the deck and floor on each side remove and transfer that to a steel patern, if your going fiberglass use some panty hose material over the deck and stretch it to the floor and secure it "good for non standard curves, then you can glass right on the panty hose to set the shape and reinforce it after you have the shape set pretty much the way you would make custom speaker boxes but be warn fiberglass in a daily driver won't hold up the same as metal
