I have just made a purchase and am second guessing myself after reading some posts below.

Running off an Eclipse deck I already have 2 10" subs with amp. I just purchased 2 sets(4spkrs) of MM6 components and a rockford fosgate 551x amp which I believe is 75w x 4 at 4ohms. Is this amp not a good match, many posts seem to suggest more power.

Also, I was deciding between the MM6s and MB quarz PCE216s, did I make the right decision?

Thanks
