Cont. power rating RMS/max. power

Does this mean that if im running a single sub i can still turn up the gain to reach up to 700 watts at 4 ohms?

or does it mean that at 14.8 vdc thats what the power would be?

 
your helix amp should do rated power, how did you get such an amp and know nothing about car audio?


I dont think you are understanding my concern or my question for that matter...

I know that its running 350 at 4ohms, but in the manual it states 350/ 700 @ 4ohms.

What im trying to determine is when does the amp reach 700 watts. In reality, any speaker resistance fluctuates as its functioning, it can go from 4 ohms- 20 ohms for that matter. In any case im assuming that during small periods of bass it can get up to 700 watts as a max for that impedance.

That was all i was asking?

 
a common test is "maximum sine wave output into a resistive load".

this provides an easier way to sort out what is distortion, and where it probably came from.

but this requires the power to change as the sine wave changes.

so on average you get 350W to the speaker, with the peak output being 700W. attempting to increase output may be possible, but would more significantly increase distortion.
