Hi,
I use 5W/8ohm speaker in my system which supports 3W/4ohm,but The sound is smaller when add TPA1517。

Hi Xiaojian,
Let's take an example. A 1kHz sinewave is added on the input. With the two speaker, the input signal is the same, and the gain in TPA1517 is fixed, so the output voltage doesn't change. By Ohm law, the ouptut power is larger for the speaker with the smaller resistance.
For the speaker 5W/8ohm, 8Ohm is the resistance, and the 5W is the maximum power rating.
Best regards,
