sonys a little too high up on those rankings. sonys suck. jl, and fosgate make great stuff. and on top of that you can have the nicest equipment with a crappy box and itll sound bad. you could have a small system ie 2 low watt 12s in a good box with a small 300-400 watt rms amp and itll sound good. key points in sound systems are focusing on rms, matching a good box with a matched rms on the amp and sub will general give you a strong consistant trouble free system. shoot for above 250 rms amp and sub for a good system. forget about max or peak amps since even bridged they might make a 100 or so watts rms. i had a 85 watt rms amp that supposedly hit 1100 watt peak. you pay for what you get. 1 dollor a rms watt generly
