A pair of very old Budweiser single 15 speaker output 150W, with a peak value of 300W. How big an amplifier is needed? Is this enough for the speaker's wedding? Please give me your opinion.

Professionally speaking, the matching principle of power amplifier and speaker is generally that the output power of power amplifier is 1.5 ~ 2 times of the input power of speaker, that is to say, the speaker of 300W-W should match the power amplifier of 450 ~ 600 W, so that the peak output of power amplifier is exactly the same as that of speaker input of -3db, which ensures that the power amplifier and speaker are not distorted but overloaded.

Enough for a wedding.
