what's a good battery?

I'm new to this site and I'm having some car problems. I drive a 1996 Camry with a 80 amp alternator. I currently have a Everstart battery with 630 crank amps/525 cold cranking amps. I have a Kicker ZX750.1 pushing 2 Kicker CVR 12s. I had this problem where my subs would cut out and my amp protection light would flicker while using my high beams, car charger, defrost, etc. at the same time. My music works fine when I'm not using any other car accessories. The shop tested my battery and my battery is bad. I am looking for a new, better battery to replace my bad battery under the hood. I want to get a Optima Yellow Top D35 810 crank amps/650 cold cranking amps. Will this battery power my amp and car accessories sufficiently? Does it matter what the crank amps are? Thanks..Car System:

Get a battery that is made by east penn.  I just bought one, and they are far superior to optimas..  You can get them at carquest auto parts.

ditto on that one! get their yellow top made by East Penn, you wont be disappointed.

Well you can't go wrong with optima either...

optima makes a junk battery these days.

OK, but EVERYBODY that has answered already has COMPLETELY overlooked the solid fact that all power in the car COMES FROM THE ALTERNATOR! The battery is there to start the car, and nothing more. 750*1.2=900 900/14.4=62.5A You even mentioned the "80A alternator". That's right at the line of being too small for that one amplifier alone, let alone all of the other accessories in the car that you are trying to power with it. You will be replacing batteries again, so that's a waste of funds right now. REPLACE THE ALTERNATOR WITH A HIGH OUTPUT ALTERNATOR! This is your only solution.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Totally agree with haemphyst change your alternator to a high output.in process of changing everything

just curios... I know why you divided by 14.4 but what was the multiplication of 1.2 for?Be original yet acceptable.

Efficiency. The 750 watts is the OUTPUT, but that doesn't allow for the heat produced. Most class D amps are about 80% efficient, so the factor should REALLY be 1.25 times, but I was feeling generous! That's 900 watts IN, to get 750 watts OUT.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
