I have a 2021 Ram 2500 6.4L Hemi. I will be installing either a 1500w or 2000w amp to push 2 subs. I believe I have the 180 amp alternator. Will my electrical system be able to push the amp without any electrical upgrades?

2000 watts at 12 volts is roughly 166.6 amps,i think you'd be wise to do the Big 3 wiring upgrade,and you might even want to upgrade the alternator to.I have a 2021 Ram 2500 6.4L Hemi.

And that's most likely all max power, not actual RMS ratings of your equipment. Huge difference. RMS is the only way you should be measuring your systemI have 1800w total, but its 1000w for 2 subs and the other 800w is mids and tweets. I don't have any issues with my electrical.
They sound like the max power ratings on those amps. Very doubtful that the true RMS rating for those amps is going to be 1500 or 2,000. Take a look at the fuses on those amps, that will tell you the true power when you calculate it based on vehicle voltageI have a 2021 Ram 2500 6.4L Hemi.

Probably right on here ↑ however, my sub amp is true 1500w RMS and amp powering front speakers is 1300w RMS. My electrical doesn't skip a beat. People get attached to terms such as "the big 3" and "HO Alternator" when the stock system will do justice 90% of the time. Now if your pushing a 5000w SPL, 4 x 15" sub system, then yes you're going to have trouble.They sound like the max power ratings on those amps.

Its RMS. I have a JL vxi 800/8 and calibrated with a SMD DD1 plus. Although rated at 75w rms, all 8 channels put out 100w rms <1% THD using a 1khz test tone and a 3db overlap. The sub amp is a JL HD 1200/1 that I have set for 1000w rms with no overlap. It is powering two JL 12TW3. So total system power is 1800w RMS... Its a SQ build and while not a "bass van" it will move your hair and tickle your nose..And that's most likely all max power, not actual RMS ratings of your equipment. Huge difference.
