well , unfortunately part of the problem is the 5x7 compnents. that size is known to well.. not sound very full. YOu may want to think about building a plate and dropping in a 5.25 components set up front. leaving the 5x7 in the rear for fill. you may also want to reduce the gain to your subs and raise the crossover freq, or run the subs full range with some tweaking of the crossover and power range. Definately start with a flat empeg eq, and tune as much as you can at the amp. I have one punch he2 10" in my civic HB and 2 sets of compnents jl vr 6.25 in front, jl xr 5.25 in rear.. for staging i usually have my rears about 30% less in volume at the amp. I am still experimenting with my 10 as i just got it.. but if your voice coils are as big as mine or bigger, think about going full range and tweaking.. however it won't hit as hard, but it will sound a hell of a lot better, IMHO. ANyway, start by turning up teh sub xover and turning down teh mid xover. open up more of a frquency range to the mids, but make sure you aren't distorting them when you turn it up. Also remember the empeg should sit around 0 db when it is at the typical listening volume.. that will make a huge diff in sq too. GOod luck.
