Requirements to power 2 Kicker L7 15 Inch?

I just got 2 Kicker L7 15's and I have a Hifonics Brutus 2000 watt amplifier for each sub on the way. What battery would be recommended to buy to handle these subs? And by experience do these 15's push to all the 2000 watts? Also I got a 2001 Tahoe so will it be able to handle without a capacitor.
