How to paint sub box?

[sendevon]

Hey i'm kinda new here i've been looking around and found a couple of good ideas for my 2004 Aveo.
The Aveo is my second car, my first was a cavalier but i sold it, i'm looking for some cheap mods, If you have any ideas thanks!
But as of right now i'm wondering how do you paint a sub box or did you all buy it like that?
This could be a silly question but i'm just starting to get into "fixing" up cars

Thanks

If you worry about your car paint then don't worry I suggest you a better car paint, Which is that (KemFill 2K HS Urethane Primer Surfacer 1.5 Quart Kit)

Its really nice and best paint kit most of auto painters use this kit for every type of car paint its not too expensive and also have good quality of paint, No doubt there are many other paint products available in the market but it is the best kit for car painting...
