i have discovered that my new shocks allow the car to rub when i hit bumps, i took out my 3 jl's and the rub is gone. i was already considering downgrading to two subs so that i could put the seats down and it looks like now is the time to do it. i was considering fiberglassing a couple of boxes on the sides sorta like the mach1000 setup, only with the speakers tilted up a bit. does anyone make boxes for our cars, preferrably something that doesnt weigh too much?
