How about putting a diode in series with power line to powered speakers  
with possibly a large cap on the speaker side. That way if the motors are  
dropping the voltage to the speakers, current will not flow from filter cap to  
motors. Of course even the cheapest crummiest scope can be a real friend  
here.
 
I implemented the above suggestion on a 12 volt video  transmitter and it 
solved my problem.
