I agree, the Jayco dealer should / will take care of any issue or problem while in warranty.
As far as ASA/Jensen goes, I wanted to add a Sub Woofer to our current Jensen sound system so I contacted Jensen for questions and support, they were great, supplied info and drawings for what I was looking to do.
The Sub Woofer upgrade went great, we love it.
