Engine Noise In Radio

[HOTROD1300]

[B][I][COLOR=blue]I HAVE A 06 RHINO WITH A JSTRONG ROOF,PIONEER RADIO AND JL AUDIO SPEEKERS . I CAN LISTEN TO THE CD OR IPOD AND IT SOUNDS GREAT WITH THE ENGINE RUNNING BUT WHEN I SWITCH IT TO THE RADIO TUNNER IT PICKES UP ENGINE NOISE. I HAVE SWAPED ANTENNA'S AND MADE SURE THE ENGINE WAS GROUNDED AND UNHOOKED ALL OTHER ACCORIES TO ELEMINATE THEM ,THE RADIO IS HOOKED STRAIT TO THE BATTERY. DOES ANYONE HAVE ANY SUGGESTIONS?
THANKS,

May need a resistor type spark plug(s) but is there even such a thing for an ATV?

All car plugs are resistor type.

Radio shack may have filters you can install to curb RFI? Check that out.
