Will these two XS batteries keep my voltages stable?

[Carnivorous18 10+ year member]

I have one D5100R up under the hood right now and am looking to add on another XS battery. Im running an SAZ-3000D and will eventually add on one or two more amps to power two 6.5's and two 6x9's. Would adding in a D1200 be now and future proof enough for me or should I go higher? I imagine I wont be going any higher than 3500 total watts

Any one?

what alt do you have?

It will help you have more of a reserve for playing time when car is off or until the battery is depleted. Then your amp/voltage will depend heavily on if your alternator can handle the current draw from the amps/can replenish the juice sucked out of the battery.

3500rms is H/O alternator territory.

I ran my TREO SSX 750.1 at .5 ohms which should be around 3k on a stock 140 amp alt.... killed my batt really quickly, before anybody picks this apart i understood the likely outcome of this, so STFU

And most cars don't have that big of alts //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Yeah and 140a is pretty great for stock. Hell, I am working with a stock 80a lulz. And some civics go down to 60a stock. However, I don't plan on having anywhere near 3.5k.

For 3.5k I'd consider 200a+ alty and a sturdy couple of batts to keep everything okie dokie.

so 3KW for the subs and 500W for the rest of the system..........................

Yep. And I have a DC 180 amp HO one in there already soooo yeah. D1200 gona do me?

Try it, if you need more, work from there.

I just dont want to have to deal with returning it because it wasnt enough for me, itd be nice to know ill be now and future proof for certain when i get another battery. And im just not positive in my knowledge if a D1200 is enough with what i got

Then get something bigger?

Well, since I haven't run that battery with that alt and those amps, I can't tell ya. Sorry lol.

Maybe someone with a similar system will chime in.

Bump for a guy with a reasonable question.

Maybe that guy can shed some light (the OP of the linked thread). He ran a beefier batt and alt on roughly same power, so maybe that'll give you some indication based on how his charging system held up.

Thanks lookin into it. If it did run well im sure it has to do with that alt of his cuz id say thats a really beefy alt
