cruise control electrical noise
 

I have a 2005 Elantra 5 speed. I noticed with the stock radio if the cruise control was engaged, it would create electrical noise on weak AM radio stations. I replaced the stock radio with a good Clarion unit and the same problem exists. I could live with this as I am usually not in a bad area commuting from home to the office for a long time.

This past weekend I had to replace the existing power amp for the radio with a new unit. I used all the existing wires and to my dismay, there is now electrical noise, hum, in the amp whenever the cruise is engaged.

Has anyone else had this problem? If not could someone rum the experiment of tuning to a weak AM station and engaging the cruise.

I also own a 2005 Sonata and the crusie doesn't create the same problem

Thanks to any help
