morel makes great speakers, they really do. heres the deal. i love the sound of polk speakers.. they suggest DBs in the rear... thats fine, but if u are going for sound quality, u dont want rear speakers. music is recorded in stereo..... not 4.1 or 5.1 so u need left and right only in the front. it will sound better and save u money.
get some polk MM or momo components in the front and get a small amp for them at least 75x2 or 50x4 and biamp them.
as for sub. i detest kicker, i think they ALL sound muddy and ive yet to hear of a sound quality competitor win or even finish top 3 in a compeition. kicker is loud... thats about it.
Subs that i know are quality, polk momo, polk mm, polk sr (2nd place world champ in MECA uses all SR speakers and a single 12" sr sub to compete, and has came in 2nd 2 years running), JL - from the w-0 up they all sound great, Image Dynamics any of their stuff, alpine type R sounds pretty good in a sealed box and can handle 1000 watts RMS, its a pretty legit sub.
