  • Hello Shubham, 

    Thank you for reaching out. The following speaker is a good selection for the AIC3100. You should be able to control the gain of the CODEC and limit the output of the Class-D amplifier into the speaker. This can be accomplished by setting the gain in a way that won't over drive the speaker or with the AGC feature.  

    You can also look into one of our smart amps like TAS2781 which features a speaker protection algorithm. 

    Best,
    Andrew
