will my stock alt keep up

[KOZ89]

with my old setup i was running 2 10's pushing about 1500 to em, and with a stock alt at around 114amps and at 1404 maximum watts(doesn't mean it actually pulled that much due to it being old as shit).

After looking through my electrical i seen that the factory wire was only a 6 awg for some reason, and pretty sure if i uped it with a 2 or 0, it would have been alot better for my system. But then again my amp was fed by a single 4 awg coming from a yellow top and i can play a song for 30 seconds, then comes the voltage drop from 14.4 to 11.3-12.5ish. So it was intense and annoying

i see a lot of people run a yellow top under the hood any particular reason for this or would i be better off just getting the xs power d6500
