rms 800w peak? i just purchased the amp but not sure if ill be overpowering them since the brz hifonics amps are certified to give true wattage, and connecting them @2 ohm it will only give 1200 watt which will underpower them,ok another question would it be better to get ported or sealed box (i drive an suv) and should i get the foam stuffing for the inside of box? and will making a custome box to fit behind a 3rd row seat of a 98 lincoln navigator cost alot(not willing to take off 3rd row seats) nd how much em i looking at for installation my whole set up i got so far is 4 10" kicker cvr,hifonics brz 1700.1 amp,capacitor. I just need the wiring nd the custome box, i need profesional advice please! Im anxious to throw in my system already, but as for now im only workin wit $350
