Who can Explain?

I just need to get this cleared out because there has been numerous controversies and i'm confused about this topic.

if your stock alternator only does 105amps, does that mean your amplifier will only produce 105amps? So if i have a XX-Hercules, which is rated at 2000rms, will the amp ever produce 2000? even if i have 4-5 yellowtops in the back?

how many amps is 2000rms anyway?

amperage itself does not determine how many watts can be produced, it is a factor, but its more about the type and design of the board on the amp and the efficiency it has

Let's assume your alternator keeps your system at 13.8 volts.

2,000 watts / 13. 8 volts = 144.93 amps

batteries would then cover the power necessary to provide the amp. in db drag street classes their engines arent even allowed to be running....

just for shitts and giggles

Volts x Amps= Power

Power = Watts

This is assuming 100% efficiency. But even the most efficient amps, I THINK, are only like 90% efficient.

Most of the energy is lost in the form of HEAT
