Okay, now I have a system that draws over 1000 watts and I hear I need a new battery. I burned out my stock alternator and had to spend my money on a new alt instead of a battery...

now I have a 200 amp alternator and a 3 year old 540 cranking amps Everlast battery.

The specs of my amp are:

(ONE) crossfire cfa1000d

RATED power at 12.5v

250w at 4 ohms

500w at 2 ohms

1000w at 1 ohm

RATED power at 14.4v (car running)

288w at 4 ohms

575w at 2 ohms

1150w at 1 ohm

As for the subs:

(TWO) Audiobahn aw1200x

12" rated 700 watt rms 1400 watts max.

I have these subs wired together for a 1 ohm load.

I have the amp (2 channel) bridged to these subs. So I'm not entirely sure if my amp is giving the subs 1000 watts, 2000 watts, or 4000 watts. the reason I put 4000 watts in there was because I hear if you bridge an amp it gives your watts by one channel X4. but if that were the case I would have blown my subs already so probably not 4000 watts. right?

... and I have a cap (3.5 farad), just to help take the strain off the battery.

FYI (I used to have 3 Audiobahns (before I sold one) on that 95 amp stock alt for a long time and up until I upgraded the power wires recently the alt eventually wore out. I was using the same 3 year old battery I'm using currently.)

Now when I visit the Kinetik website and use the calculator it tells me I need 2 dry cell batteries one about 1400 watts and the other 1800.

The thing is That 3 year old 540 ca battery DOESN'T DO BAD AT ALL, I only get minor light dimming on max volume. So why do I need such high amp batteries if a little 540 amp wet cell battery can do it? Now I know its making my alt work harder then it should so I was planning on getting a higher amp battery but not as much as the site suggested. What should I do?

So my two questions are:

1. what are the actual rms watts of my system?

and

2. what kind of battery should I purchase for this?

(my old alt was 95 amps so i figure 95*13.6 = 1292 watts are for all my stock electronics required.)
