In that case run a Fi Q 10 or 12" fully loaded Daily option off your BRZ it will take it and love it. You could give HO Daytons probably 800w each in the right box which would save you some SQ from the BRZ since it won't be cranked up, also with the HO configurations with impedance you could just run them @ 2 ohms off that amp and power them and have a nice clean signal.I don't have a 500.1 I have a Hifonics brz2100.1 and price isn't really a problem just want something that will last and bump while still sounding better then the l7s or should I just go with a sealed box for those?
