So if you set up an lc oscillator with a side route, and a capacitor with a diode, you will collect the compressions, and u should end up with more than 100% after the osc has settled!

what do u think?

Hello,

It will never work:

How would the resonant circuit be exitated?

Hello,

Where will the energy come from for the oscillation?
It will never begin on its own.

That positive and negative stands for the connection to the "music" , and then the side channel connects to the speaker.

Maybe it doesnt work unless u run on it a timer, but I was wondering if you made the LC oscillator run at 10x the maximum frequency of the music, maybe it could be continuous?

But it would have to be a little capacitor, it is an amplification only for very quiet signals, but I wonder if you have a heap in parallel - then that could make it loud.

Your simple circuit is not an oscillator.
If you connect an amplifier output to the capacitor then the amplifier output will be shorted when the amplifier plays high frequencies.
The signal is not boosted.
Maybe you need a speaker crossover circuit:

Thanks for that Audio Guru.
Before anyone kills me about it, I posted this a little early, but youll need to fill up capacitors one after the other, because it already maxes the first cap in one hit.
