I like the sounds of that set up.(polk mm6501 and polk mm691 for lids) thats the rout i would go. I think its gona kick A##. I got the J&M rokkers for the fairring and the lowers with the new polk pa4000.4 amp. The amp kick's AS#. Im not happy with the J&M rokker lowers. cant relly hear them. gona add some 6x9 lids real soon
