Period
Depends on the light fixture.. Is it a group of LEDs or single bulb...
Regardless. The OP needs to “decouple” the RFI on the speaker and the stereo since it’s picking up the emitted RFI and amplifying it.
The best resolve is to use a clam shell ferrite bead on both the 120 AC line for the stereo as well as the speaker output leads....

The bolded comment is a "intensive, technically challenging repair" for someone who isn't familiar with electronics or, especially for someone whose first question is, "How do I remove my stereo?".
Often changing the polarity on the voltage input to the ceiling light fixtures will "put the interference on the ground side" and stop the RF transmission from the voltage regulator... It's a quicker remedy (if it works) and IMHO, worth a try before attempting to install ferrite beads for someone who isn't familiar with electronics.
I've found that it works about 50% of the time, costs "nothing but a few minutes of time" and solves the problem quickly. For me, it's worth the effort, I suppose for you, it's not. To each his/her own.....
