Im trading my 2018 silverado in for a 2022. I had a Kenwood 6705s in my truck. I would really like to keep the factory HU this time. In 2018 I needed a $800 optical line out thing if I wanted to keep the factory HU. Whats the best options out there now? Also will my sub box fit the new 2022? Its a double cab and my new one will be as well.
