Need help with car battery

[Trosky]

I have 2 12'' audiobahn subs 500rms each. Has a 2300 watt Audiobahn amp powering them.

1000watt profile amp powering 4 infinity kappas (110rms) per speaker. The speakers aren't bridged to the amp.

Both The audiobahn amp and profile amp are using the recommended 4guage wiring kits.

My lights dim just barely when i turn everything way up. I don't have a cap and was just wondering if i could buy a better battery and what would be the specs of what i would buy. The one i have now says 1600watts it seems to power everything fine even when turned way up. But my lights dim just barely that you cant hardly notice it. And I have to get a new battery anyways so instead of buying a cap Is there a better battery i could buy that would solve my problem and provide more power to the amps with out burning them out or breaking them.

I drive a 2000 Ford Explorer "Not eddie bower edition"

I can get a cap if you think that's the best solution to my problem but I just figured i could get a better battery cause the one i got doesn't seem to be doin a bad job.

i dont think a cap will help with that much current draw. your hct prolly has 4 40 amp fuses and with the other amp your prolly pulling 200 amps easy. adding battery will help or maybe solve the problem in your case

Ok I read "the big 3" thanks for the help and don't feel like doing that unless the replacement battery im getting for my explorer doesn't solve the problem. So can you guys suggest some batteries or even the specs for a new battery that would be good for me like "wattage" etc.. I think we may get it from NAPA so you can trade in your old battery. And would it be ok to get a battery that may have more power than both amps need? I don't want to kill anything. Thanks for the help again i greatly appreciate it!!!

A bigger battery will never kill anything. Your amps will just draw the power they need from them. And don't be so lazy, you read the thread on the Big 3, so just do it. It's obvious that your either cheap or you just don't have the cash to buy a real battery so do the Big 3 upgrade and if that doesn't solve your problems then look into a Kinetik Battery. And batteries don't go by wattage, they go by amperage draw, hence the term "CCA or Cold Cranking Amps".
