painting carpeted speaker box

i want to color match my speaker box. so its finished like car paint. what are the steps to do this?

Make sure all the dust is blown off the box and lay on some good quality filler primer. I use Slick Sand and a 2.0 tip spray gun. (it may be possible to do it with rattle can primers, but you will need alot of it).I do a good medium coat and let it sit for a couple hours. This will allow the MDF to soak in whatever paint it will. MDF is alot more dense than your average wood so it doesn't soak in alot, if any, primers.Clean the box again of any dust and spray on a good heavy coat of filler primer now. Let that dry and then guide coat it with some flat black paint.You can block it out with some 150 -180 grit and see if you have any low spots. If you sand down to the MDF before all the low spots are gone, spray on some more filler primers to fill it in and cover the bare MDF. Repeat till you have a smooth primer finish.Then top coat with whatever paint you want.                                                          -jacked from "Epicenterdesigns" on fiberglassforums.com
