How much system wattage before running into battery problems?

[neonblack 10+ year member]

At what power limit would you start to drain your battery too much (eg. standard car, standard alternator, etc.)? I have 4 ADC components (each 100W) and have 2 8" subs (each 150W) and may be looking to upgrade my subs to 10" x 2. My total system could easily reach 1000W total. 1000W could drain the battery pretty quickly I suppose? (I don't run the stereo a great deal these days though.)

every car is different but 1000watts rms is around where most cars start needing electrical upgrades such as big 3, upgraded batt and such. but like i said every car differs

Yes, I see that 10" subs are scarce at 150W-200W range. I suppose they need more power to drive them than 8" subs. If I upgraded to 10" x 2 subs that would put my battery in jeopardy I think and I don't want to mess with that. I did try the Big 3 upgrade about 6 yrs ago and my battery went dead within a month. I'm sure I wired it correctly according to tutorials. I have 8" x 2 Kicker subs (in separate fiberglass sealed enclosures) and Kenwood 7201 amp (150W @ 4 ohms, 2-channel) to power them. The subs are subtle and not as deep as I would like. Thanks for feedback.

How much upgrading do people do to their car's electrical system to drive 600W-1000W subs?

How many amps is your alternator and battery? And you could probably do it for 200-300 dollars for a decent battery and alt but you may just need a better battery.

With everything you're stuffing in that burban of yours you ain't got one or better?

i have four agm batterys in there totaling 410 amp hours - i dont drop below 13 currently with ddm3a - but when atomic 5k goes in idk if thats enough... might be time to think about adding alternator #2

Btw my battery isn't 1000 amp hours i don't think its just 1000 amp max capacity or something. I don't think 1 battery can do that.
