Make some kick panel pods! Lol fiberglass in isn't all that hard.
It's a much better sound quality than the little 4 inches in the dash pointed straight at your/your passengers legs
I also have some 6x9s mounted on the floor behind each seat for more mid/highs, but then again I've also got 2 12 inch woofers as well.
(also before someone kills me for all that overspray, it's plastidip. It rubs off I just have yet to do it... Lol)
