I hope someone has been there done that. I dont listen to the radio much when I drive, but I always have a annoying buzzing which changes with rpms from just the right speakers . Even with the radio off I have the buzzing

I have MSD ign. Is there a reason and cure for this? or could it be the speakers are damaged?

It could be the ignition wires. What type are you running? Solid core would put out a lot of interference.

I believe MSD sells a noise filter to combat this. Your speakers are fine.

How close are the MSD wires to speaker/radio wires?

I've had my MSD installed on my heater box for 3 years and haven't had any noise. You can try and twist any of the MSD and speaker wires to help keep down interference. What plug wires are you running? Alternator can also cause this issue.

plug wires - get a set of quality spiral core wires - MSD 8.5mm Super Conductor, Taylor Spiro-Pro, Moroso Ultra 40, etc...

I do have a good set of wires (MSD 8.5mm Super Conductor) and the reason I didnt consider the plug wires is because I am only getting it on the right side speakers.

I will check my wires to see if they have any scuffs or damage. thanks

might be your alt doing this as well..

you need their noise filter,,,i have the same problem,,very annoying.
