I have one of the red Sanwu boards and would like to use it for a speech Public Address system. The plan is to use it from a 12v leisure battery through a 12-36V DC-DC inverter.
Is there anything I should look out for or is there a better amp for this project, should also mention that quality is not that important and it will be used only intermittently.

Hi, think added to the input of the amplifier a high-pass filter to avoid amplifying very low notes, like blows on the microphone. this in order to saturate the amplifier and speakers
A good point. I like to see a 75Hz HPF on this type of input but had forgotten to add it to my block diagram.
