From 2 ohm mono to 1 ohm????

Well, "in theory", it would output 800w RMS.

However, due to several factors such as internal losses due to resistance and heat, limitations of the amplifier's power supply, internal components and design, etc etc...it may or may not be that high of output into 1ohm.

Also, by running the amplifier below the rated stable impedance, you are running a risk of damaging the amplifier.

 
Thats what i was thinking also i just wasnt for sure so i figured id ask it. It gets warm but thats about it i have 2 power supply cooling fans on it, although it does drag my voltage while idling down from 14.4 to 10.3 so my fluke says. And i have ran it down to a .5 ohm load so what is the output on that load?

Thanks for the input by the way!

 
So i double the wattage once again? I only use that amp at that load for burps.
So you can do this on your own.....you can use simple ohms law to arrive at the "theoretical" power output.

Start with the known figure; 400w RMS at 2ohms.

Using this, we can use ohms law to find the voltage the amplifier is capable of by; V = sqrt(power*impedance).

So, sqrt(400*2) = 28.28V

Now that we know the voltage, we can find the (again, theoretical) power output at any impedance by the formula; power = (voltage^2)/impedance.

So, for 1ohm, (28.28^2)/1 = 799.75w (we'll just round up to an even 800w //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif )

And for .5ohm, (28.28^2)/.5 = 1599.52w (again, we'll round up to 1600w).

So yes, in theory at .5ohm the amplifier should produce 1600w. However, as I said before...this is more of a "perfect world" answer. And as I'm sure you know, the world is rarily perfect //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif. Due to several factors the power output could be significantly less.

Also depends on if the amplifier is regulated or unregulated. If it's unregulated, the power output will reduce by a decent amount based solely on the drop in your system's voltage.

 
Im not sure if its unregulated or regulated, how can i tell this?
Call or e-mail the manufacturer and ask //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Or if you have the manual, it may state it in there.

 
I have a question....

If "in theory" your supposed to double the wattage if you divide the ohm by 2, then why is it that my kenwood amp is rated at 900rms @ both 1 and 2 ohms? If its rated for 900rms at 2 ohms then shouldnt it be rated for close to 1800 rms @ 1 ohm. Or if it only puts out 900rms @ 1 ohm wouldnt 450-500 be a a more accurate rating @ 2ohms? How can it put out the same power at the 2 diff ohm laods?

 
So what would make my amp UNREGULATED? Can you elaborate on unregulated and regulated whats the difference between the two??
An unregulated amplifier's output will be affected by the voltage input from the electrical system. As the voltage drops, output will likewise decrease. As voltage increases, output will likewise increase. So, if the amplifier was (for example) rated at 12V, then at 14.4V it would have slightly more output than rated, and at 10.3V it would have lower output than rated.

A regulated amplifier's power output should not be significantly affected by fluxuations in the voltage input.
