I'm down with that. Got two sets of Boston 6.5 x3s for mid, mid bass and tweet's. One Boston 4x6 for a center channel. For Bass it's 2 15" MTX Freeair. Can't speak on the RM9s.BeaverBrad said:I am planning on getting a boston acoustics fs60 components system in the front (6.5s) and RM9s in the back (6X9s). I will power it with a 300X4 JL amp. Also I have a riocar (20gig mp3 harddrive). What do you guys think of this setup, any suggestions?
