do you think this amount of power to them in a sealed box, 1 cube per speaker is gonna blow them? if so i will go with 600.1

 

sealed you can have more power, but the JBL does around 1300-1400 watts...do the 600.1 or look at other 1000 watt amps

 

I was looking at the same setup...I had the same question too, lol. I think I am still going to go with the JBL 1200.1 and just turn it down, that way if I decide to get bigger subs or a 3rd Type-R I wont have to get a bigger amp .
