What size battery for 2500watts

[stephens30228 10+ year member]

I just bought a Re Mx 18" D2, and when I got it wired up and tuned I realized that either it is running hot from the temperatures here in Georgia being 95+ or that my crescendo 3kwp is being pushed too hard. I have the gain set to like 1800 watts with the DMM, but I was suggested that I get another battery. I am looking at getting one used, and was looking at XS in the classifieds, but with so many batteries to choose from what would be suit my application on stock everything? I just don't want to screw up the amp even though it may not be from playing as much as just normal heat from being in the back of my SUV. Thanks.

For a few minutes yeah, I haven't turned it up since then.

Err, harsh since I had my DD9512 running at around 1700 @ 2 ohms and had no issues I didn't think it would be a problem.

you are damaging everything in your vehicle by putting that much of a load on stock electrical.

Okay, so with that being said, what do you suggest? Lol, I get that I screwed up.

So 1 3100 would be enough for what I am doing?

With a Highout put alternator, yes. Unless you have a large stock one in there now.

130 amps is all the alternator I have, and wife is complaining about how much I am already spending so I am trying to go the cheapest route.

If you want to go cheap dont run that much power.

Okay, so if I may ask without getting bashed, why did my DD @ 2 take it okay, but now the amp is overheating @ 1 with only 100 or so more watts?

lower impedance is more of a strain on the electrical.

So I would be okay with a 3100 and an alternator that idles at 100amps and peaks at 200amps or what would the rating need to be? Sorry about all the questions, haven't had to worry about this issue yet.
