Das wird aber nichts bringe, siehe MSC|StalkerGERs Antwort.
Die 830 W Leistungsangabe(PMPO) ist eine rein berechnete Angabe.. eher geschätzte Angabe.

Was sagt mir die Leistungsangabe eines Verstärkers, was ist RMS?

Spoiler für Berechnung der PMPO Leistungsangabe:

Admittedly, these "new" power rating are not used by hi-fi manufacturers, other than in the low-end equipment, which possibly rates "fi" at best.

These new terms are soundly (no pun intended) based on the science of marketing, and PMPO is mathematically expressed as

PMPO = Actual_Power * k

where Actual_Power is calculated by the formula below, and k is a constant whose value is approximately equal to one's grandmother's age, divided by the square root of the distance from the office to the advertisement writer's normal place of abode - measured in millimetres, inches, furlongs, statute miles or pounds per square inch - as appropriate, to provide the number you first thought of.
In the unlikely event that the value of k cannot be calculated from the above formulae to provide a totally meaningless (but plausible-looking) final result, a value of between 20 and 50 shall be used.
