How many XS POWER XP3000's do I need.

[southpaw_inkz]

I have a CT Sounds 4000 and I have it powered by 2 yellow top optimas and the stock under hood battery. Im about to strap a second 4000 to it and move my two optimas under the hood. Ill be wiring three 15" mojo 5's to them at .66 ohms and I have a Singer 275amp alternator along with my stock 160amp delco. My question is how many batteries will I need in the back to support my amps and keep them in the high 13's on heavy bass notes ? I want to use the XP3000's with toolmaker buss bars. Any information would be appreciated.

Strap in at .66 will make each amp see .33 and I don't think those ct amps will like that very much... With those alts I have I'd want at least 5 31d in the back

I honestly didn't know that was how impedance worked on strapped amps. I thought they'd see .66 each. I guess I could run my dual coils in series then parallel the 3 subs for 2.66ohms giving each amp 1.33 ohms. Should still produce plenty of power for those subs. Thank you for that info !

Thanks man. I was looking for some kind of estimator like that. Appreciate it.

Strapped at .66 your amps are gonna blow for a fact. Any way 55 ah per 1000 watts rms and you'll need at lest 450 amp of alt juice to feed them

As many batteries as you can fit, if your anything like most of us you will need the extras eventually for amp upgrades lmao.
