New System, Opinions, Comments, Ideas pls

picked up some 300w 6x9 3ways for free today and am installing them in the rear, and some 4" 80w kenwoods for the front, also a free pickup so they're in there til i have this other system design down to an absolute tee. was looking around on the net today and saw the mtx d class amps are pretty good, is this agreed? what wattage amp would i be looking for with those subs? ta once again:)great effort comes from great attitude - pat riley

Kicker KX600.1 mono? Bridged RMS power is 600W x 1 @ 2ohms, this would be fine for those twin pioneer subs right? thanks for the input :) great effort comes from great attitude - pat riley

yes/no? a storeman at hi-fi supermarket actually recommended the new Pioneer GM-D5010M which i'd run at 500Wx2@2ohms or 300Wx2@4ohms, which of these two amps would you recommend? and which of those two wiring options for the Pionner amp? cheers and have a merry christmas!!! great effort comes from great attitude - pat riley
