these are my room mates air guages in his frontier, but you could do something simliar in either the bottom box w/ a sheet of ABS, or in the pocket.. depending where your sterio is.

eq's are only noise makers unless you get it tuned PERFECTLY.. and yes i know your an installer.. but still.. ditch it.. get a cd player with a built in EQ and mount the guages.
hahahahahahaha.. only one i have and want is the tank guage.. so you don't hit some switches driving down the road w/ 20 psi in the tank.. always an awkward moment
