Hello everyone. I am work on a project. I use Tmrpcm library for talking my robot. But my robot voice is so low. I use arduino, 10 w/8 ohm speaker and arduino sdcard module. How to increase my speaker voice.
✓ I convert mp3 file to waw file
✓ ı use transistor but ı can't increase
Show your circuit diagram.

To drive 10W through 8ohm you need about 9V and about 1A.
Since you have not shown a schematic for your project, I can only assume you are using DC to drive the speaker. That way, you are ONLY driving the speaker in one direction and relying on the speaker to spring back so the next pulse can pull it in, again. Normal speaker use is to use AC to drive the speaker cone both inward and outward. That is what creates the sound waves in air.
Yeah ı use dc energy from arduino. How to do it. How have to use ac volt?
Amplifier board
Which amplifier. Do you know its name? Does it matter which amplifier ı use?
