look at the pic above get a idea of the layout and then wrap with some velvet or other type cloth which gives it the smooth round curve's. I use regular cotton! It's cheaper..then use paint brush and fibreglass resin to cure...then use some bondo and sand your life into a miserable obliss.... go to youtube and search.. They have many video's showing the whole process..
not as specific but it give you idea.. search more..
First one, like the second one most likely has MDF underneath the fiberglass.
You can cut the circles with a simple jig saw. Or if all you want is a round hole you can use a hole saw. Pretty sure you can rent a hole saw if you need a really big size. I'm guessing 6" go for about $30 or so.
In the lower pic, what appears to be where speakers are going it looks like they used two pieces of MDF, cut two holes, one smaller then the other, then glued them together.
the first picture you see how the curve is symetrical on both sides? yeah you would have to shape it in mdf... i was wondering how do you get that shape? is it just drawing a pattern then cutting it? and the lower pic you see the center counsel how do you cut that shape?

The easiest way I know to do such curvy work is to mock it all up in corrugated cardboard and masking tape. Cardboard is easy to work with and you can add to it and subtract from it until you have just the shape you want. Then you can reproduce it using as many plywood or MDF ribs as you want, as in your second picture. Cut the ribs with a saber saw or jigsaw. Cut the crossbraces with a table saw or radial arm saw, or with the saber saw if you can make very straight lines.
Chances are good the rings were cut from MDF and finished with a router.
Assemble using something like Gorilla Glue (urethane glue) and small nails if necessary (the small nails are only there to hold the assembly in place while the glue dries). Then cover it with fleece and make the fiberglass skin, as in the first picture.
Look at Nexson's threads here in Fabrication to see how he works. His products are beautiful and curvy, and his finishes are OEM or better.
. . . and the lower pic you see the center counsel how do you cut that shape?
The console is much like the dash: mock up the shape you want in cardboard and go to work with the saber saw. Brace it well so it's strong, and don't forget to build in fastening points so it will stay where you want it.
. If just enough is really good, then too much ought to be perfect.
Go to any hobby shop and get flexible curves. Basically its stiff rubber you can bend and its about half inch around. You can get them in 6, 12, 24 and 36 inch lengths. Lay that down on mdf and play with it till you find the curve you want and then trace it. Jig saw that out but leave the line. Double side tape (Kent tape only, its yellow) your flexble curve back down and router the rest off for a perfect finish. As far as everything on the dash and the box in the first pic that is all built with jigs and a router. You can get jigs from mobile solutions or select products. Then stretch mold fabric (100% Polyester Fleece) over your part and fiberglass resin that to make it stiff. Body fill. Sand. Sand. Sand. Sand. Sand.........etc.
Thats how I built the dash in the pic and the trunk
