Ideas for speaker cover?

[MIF4]

So i got my PG speakers in, has all new PG 16ga wire, everything mounted yada yada.

Anyway i had to use a spacer so it would clear the window, so i just bought a plastic 1/2in one off ebay.

Mind you this is my winter beater so i didnt want to spend alot of money on anything :)

Either way using the spacer caused it to hit the factory grill, so i cut that off and now im left with this

Now its not that i care how it looks really "once again my beater car" but i just dont want them getting stolen or anything. Any ideas on a cover?

Cover the opening from the back side with grill cloth, or make a speaker grill that attachs from the back.

Grill cloth is a good idea, where can i get some?
