I want my system to be efficient and not drop voltage at 1ohm (1500wat

[tac2137 2]

I have read a little bit up on XS batteries and Mechman alternators But on Mechmans webite, when i enter all my car info (Car brand-Nissan, Model-Altima, Year 2001. Nothing pops up) What are your opinions on what i should need to run Two Sundown SA-12 D4s on a Sundown SAZ-1500D v3 at 1ohm (1500watts) with 1/0 Xs flex wire?

Do big 3 wiring and get the biggest AGM battery you can fit under the hood. Buy a volt meter and monitor voltage, if droping more then you want than buy an AGM battery for the trunk area.

I'm guessing this is a 100 amp,I would suggest the big 3 with at least 0/1 100% oxygen free copper..No CCA garbage you can leave your factory wiring in place and this will not effect nothing at all...will work as a back up if your big 3 wiring was ever to get damaged..As it will travel in the path with the least resistance...I would suspect this will fix any voltage drops with your current set up....For future reference you could probably email mean green and they could rewind your factory alt to fit your needs...

That's what I would do ! It should work for the power you will use.
