two subs ported and one sealed

[mr.cheez 10+ year member]

Sorry if I'm posting this in the wrong area. I just got on this forum. I got a whole Infinity system except for my subs. I have am Infinity 1211a amp and I plan on buying 3 Infinity Kappa Perfect 12 DVQ subs. The amp puts out 1300 watts rms @ 2 ohm and the subs are 400 rms each. I believe I'll be running them parallel to get a 2.67 ohm rating. The subs are 4 ohm dual voice coils. Anyway, could anyone tell me about how many watts would I possibly get to each sub. Also, I want to port two subs @ 40 HZ each and seal the third sub, would this cause any problems? The subs will all be in the same trunk. Can anyone help, thankx

mmmmm sealing one and porting two?? i would either go all ported or all sealed. you could probably get 400 to each sub wich would be good.

If you are going to port and seal from the same amp you will need a crossover for each sub because the amp will need to be set differently depending on sealed or ported
