Im running a rockford fosgate T25001bd wired down to 2 ohms for right now at 2 ohm the birth sheet says 2220 watts i would like to some day drop it down to 1 ohm but that will push 3250 watts and the efficiency goes down by a good amount will i be fine with the stock alt with the xs? i dont have the money at the moment to get a ho alt from dc

these are the efficiency specs

87% @ 4-Ohm

86% @ 2-Ohm

75% @ 1-Ohm

On one battery you are in the rated range @ 2220, might want a second when you step up the output.

As for your alternator, that's not going to keep up.

I've got a 5100r and a 1200 on a 60 amp alt, with a sundown 1500 and my alt can't keep up. No way yours will with that much power. Lower your power levels 'till you get more power available.

I'd be surprised if you're not having major voltage issues already running 2k+ with all stock electrical. You definitely need to get some in there.
