I believe MSD sells a capacitor that may filter out the noise your experiencing in your speaker circuit.

If you read the instructions that are linked to from that page, they include basic information on how the
MSD box may generate noise in your speaker circuits.
You may know all this but I thought I'd try to help if you didn't.
Also, since that capacitor is quite expensive, you may be able to research online its actual rating and purchase one cheaper somewhere else.
