loud, balanced, tuned system

my grand marquis has a sony head unit, 2 pioneer stereo amps, polk db690's in the back, infinity kappa 680.9cs components in the front, a pair of memphis audio m3 12's in the trunk running on a memphis 16-mcd1.1100 amp. updates in the works include HO alt, big 3 upgrade, optima redtop under the hood, yellowtop in the trunk, 2 runs of 1/0 knuconceptz power wire, new ported box, and some other minor things. sounds good as it is, however!
