Do i need an extra car battery for my subs?

I have to 15inch kicker L7's. RMS is 1000 watts each. Its running off a kicker ZX2500.1 amp. I also have two kicker KS600 speakers which are 65 watts each and its running off a kicker ZX350.4 So i was wondering if i could keep my standard car battery or if i need to get a new one?
