   I ran 2 Jeeps with a 706 in it.  20 watts on 2 meters, 100 watts on both   
   6 and HF   
      
   Make sure your amataur gear is thoughily grounded.  If possible, keep   
   the main unit as far to the rear of the jeep as possible  Run the power   
   from the battery (with appropriate fusing) and not the cigarette lighter   
   or accessory outlet   
      
   I did get some stereo front-end overload, mostly on 40 meters, so I   
   turned the stereo volume down   
      
   Each jeep left this wokrd with over 250k miles and I never had to   
   replace any audio component or vehicle computer component   
      
   But, yes, if you damage many components if you aren't careful with your   
   installation
