Question Concerning ohms

[guitarman626 10+ year member]

Ok, im powering 3 subs. each with a 300RMS max.

So I obviously need at least 900RMS from an amp, and I figured a 1000W Mono amp is my best bet.

Heres the question, when im looking at amps and their features, I see things like this:

Mono subwoofer amplifier

1,000 watts RMS x 1 at 2 ohms

640 watts RMS x 1 at 4 ohms

Ok, so my subs are 4ohm DVC woofers; but i know that when you wire 3 subs to a mono amp, the mono input is pushing about 2.7ohms. Correct?

So im really confused about amp descriptions like the one above. Does 1,000 watts RMS x 1 at 2 ohms mean that if the mono input is pushing 2 ohms, your subs have 1000W?

If this is the case, and I'm correct about the fact that 3 subs into a mono amp pushes it's input to 2.7ohms, then how many watts will my subs get from an amp that has 1,000 watts RMS x 1 at 2 ohms?

(If I'm simply wrong about everything I'm saying, A quick lesson in how this sh*t works would be greatly appreciated!)

Thanks,

you'll just be getting like 800 or something, your ohm load is between 2 and 4 so youll be getting between 640 and 1000 rms
