How much power on stock alternator?

[timma100 10+ year member]

Okay simple question, going to run XS D2400 up front, and another in the trunk, maybe D3400. Car is an 05 Altima 3.5v6 /w 110A stock alternator. Big 3 isn't really an option as the charge wire is fused and monitored by the ECU. But I can ground the **** out of everything else. What kind of power could I run with the two batteries? I'm aiming for a SAZ-3500D (maybe a v.2 when they come out) I know they are crazy efficient. Also I wont be doing any full power demos with the car off..

Can you add a piece of 1/0 wire in addition to the fused wire?

I wouldn't do more than 1500-2k without upgrading the stock Alt. I'm 99% sure 3500 is definitely out of the questions even if it is running.

I assume I could, but part of me doesn't want to. Its good size wire :\.. The grounds are horrible, the battery has a single line to the frame. So thats first on my list... But I am really cautious of that charge wire :\

you should be good on a stock with a BEEFY battery bank. and a good 1/0 power front batt to back back & a 1/0 ground front batt to back batt

lol i have a HO alt and still dont do demos with my truck off. i have 5hitty batts tho but i working on getting some batts and do multi runs of 1/0 gauge(2 power runs & 2 ground runs) and however i still wont demo with the truck off lol...

also why dont you just add the big in with your stock wires. thats what i did. i my big 3 in 2ga and just left the stock grounds and stuff connected as well

Even adding another line for the alternator, I just wonder why its fused :\

not sure on that. probly like any other wire. in case of a surge and anything that can cause a fire

True, alright so Big 3, and XS 24 up front and 34 in back. Do you think I could safely run 3500?

IMO... i think you will be fine with that. Ive seen worse. my friend had a honda accord walled with 2 18s. he had 4 5hitty batts, big 3, & only a 90a alt powering a American Bass vfl500.1 wired at .25 ohm, for a year and the amp still works. yes his voltage ran a tad low around the 10.1v to 10.5v average lol, but again he his batt bank and alt are smaller then yours and you have a smaller power more efficient amp. so IMO, i think you will be ok
