I think you need a compressor

Sounds like you are in need of an audio compressor. There is a device that is sold for metal detectors for this purpose. It is also available here in 2 different patents. A very simple device that is quite effective.
Good luck,

I agree, a straight amp is likely to blow your eardrums.

It will blow stability of DC power, also. Quick changes in current consumption will provoke oscillations.

pcb

is there a site that sell it?
thank you

Yes, you can get it at Kellyco

Kellyco sells it under the name depth-master. I didn't look elsewhere but I'm sure others sell it as well.
Good luck,
