Kick panels with speaker holes?

i made my own out of 'glass about 6 years ago with a set of 6.5" alpine components. i tired a few other things and nothing compared to this setup. bass to spare and some good highs too with separate tweaters. i have a JL 75x4 amp in the trunk. i have some good JL 6x9s in the package tray, which has room for improvement, they sound like crap now compared to the kick panels. the 6.5s take up a lot of room down there though.
