After seeing a Nutek truck at a dealership ,contacted them.The experience with the installer was fine,it's Mike@nutekelectronics.com who was abrasive,and lacks customer service skills during post sales.Until Kenwood helped,looked like I was stuck with an Excelon head unit that wasn't properly functioning because Mike, and crew aren't authorized to sell this top shelf line from Kenwood, thus not TRAINED on it . Thinking any car dealerships who want to use a car audio installer, reconsider Nutek if your customers matter .When we had stuff done for our cars at Paradyme Sound & Vision in Sacramento,it was so much better.
