i got a buddy who is has a full sponsorhip from MA audio. at a bbq i was at for the audio team he's on, we talked about my car and setup b/c i currently am running 1 ma audio 1000watt rms amp that i love. he was saying there new line of amps are great he loves them and personally has used there HC amps and Class X amps, recommends them if you can find a good price on them if not then don't get em b/c they are pricey. the synergy subs he said are pieces of crap don't buy em you can find many many dif. subs that sound better and are better. he won't touch an MA sub period, so i would just take it from him and not touch there subs.
