With the minimum recommended amplifier headroom of 3 dB, then you need to choose an amplifier that can supply at least 1,995 watts to the loudspeaker. Equations used to calculate the data: dBW = Lreq - Lsens + 20 * Log (D2/Dref) + HR. W = 10 to the power of (dBW / 10) Where: Lreq = required SPL at listener.

• The Fully Differential Audio Power Amplifier 1.1 Power Into a Speaker Before discussing the various audio power amplifier configurations, some basics about output voltage, speaker impedance and output power are presented. 1.2 Speaker Impedance In the case of audio power amplifier design, most speaker impedances are in the range of 3 Ω
How Much Amplifier Power | Crown Audio - Professional ...

If you are playing light dance music, the amplifier's 4-ohm power should be 1.6 x 100 W or 160 W continuous per channel. To handle heavy metal/grunge, the amplifier's 4-ohm power should be 2.5 x 100 W or 250 W continuous per channel. If you use much more power, you are likely to damage the speaker by forcing the speaker cone to its limits.

20/4R = 5 Amperes of current into the speaker. 20V x 5A = 100 Watts. The 5A is supplied from the 30V supply (through the transistor) to the 4R speaker. 5A x 30V = 150W. 50W heat is dissipated by the transistor into the heat sink. Therefore at full power the amplifier is approx 65% to 70% efficient.
