i wouldnt put foam behind it, i would buy a dynamat kit from best buy circuit city etc, get the one that has two 12x12 sheets, it should be about $20 then make a basket behind the speaker, it will sound much better enclosed and perform better as well, if you just leave a space behind it they will still sound good but by enclosing them you are giving them a tighter airspace that will make them sound better, when i used to install stereos i would always recomend that to people, hope what i explained makes sense, with the basket and all
if not let me know and i can try to make a make shift diagram for you
