gonk,what i suggested was only to get a feel for the speakers,if they sound good up front they will be fine in back,if they sound so-so up front they may still perform in the rear,but for that kind of money(they seem to be pretty proud)i'd want a kick butt pair of speakers!i would wanna rock 'em up front to make sure they 'are all that',know what i mean?

look at me,i'm runnin' 601's up front,when the time and $$$ comes,they'll go to the rear(and perform!)
