Power for 2 Crescendo 5500s

[Guv]

Im posting for a friend whos wondering how many/what brand of batteries would be sufficient for 2 crescedo 5500 watt amps. Im not asking necesarilly for what brand is the best or whatever. Im just trying to help him choose. Budget is not a huge issue he wants to get it done right so any input is appreciated. Thanks

... You won't be able to run 2 crescendo 5500s with just batteries even if you had 15 of them. If he has a single 270a alt then he would need 8x XS Power D3100s and even then you wouldn't be able to run full tilt forever. You would eventually kill your batteries, unless you play conservatively (ie not full tilt 100% of driving time) (Which I do )

Probably 6 to 8 of the biggest xs batteries you can fit/afford and a couple HO alts should do it. Possibly 3 alts.

Ive got 2 5500s with a 270xp and 5 d3100s i stay 12.9+ at idle full tilt, I demo all day like that and they love it.
