    Hello

    I have an amplifier with two outputs of 40w, I need to amplify this signal to 200w.

    Is there any equipment that amplifies an already amplified signal?

    Thank you

    You need to drop the output back down to line level using a speaker to line converter and then use a power amplifier of the power you desire.

    Not sure why you would want to do this though?? The difference in perceived loudness wouldn’t be huge and you will degrade the quality as well.

    A line driver will take a RCA cable 1.5-3.0 volt output to 12-14 volts, make a huge difference and you'll probably need to turn the gain down

    Not sure what that will achieve?? Line level will have a voltage swing of +- 15v peak to peak in any case.

    The op wants to take the output from an already amplified signal and feed it into another amplifier to increase the power output. Increasing the voltage swing won’t achieve this.

    Ok I was thinking he wanted more power from 1 amp. Buy a bigger amp
