From what I've always been told around 1500 rms is the most you want on stock. Of course that can change with your stock alt size and battery choice. Personally I have a stock 150 amp alternator with the biggest agm battery I could fit under the hood with no big 3 and have 0 issues. I am running an IA 10.1 (1200 at 1 ohm) and a Diamond D5 600.2 (class a/b 150x2 at 4 ohm) for comps.

Its highly dependent on the size of the alternator.
How do I figure that out ?

i have 125 amp alt (get 14.7 or more volts at idle) and agm under hood no problems with over 900 but i think 1200 will be my max.. for 1500 just make sure your alt is good and u have at least 1 agm batt

Yea you can probably get 1500. I've got a Subaru Legacy with 1200 on the sub, 200 on the 4 channel and no problems at all, and I doubt Subaru was trying to put the kind of alternator in there that you could power a house with, if ya nameen.

Ive ran about 3k on a stock alt. But with big 3 and 2 secondary XS batteries.

1500 is generally the safe zone assuming stock alt is reasonable, and you at least do a decent starting battery.

Oh, just for future reference. Put $800 OBO, or you will only get that $600, or less. ;)
