I spoke with an aftermarket audio installer the other day in regards to upgrading the factory sync 3 system in my 2016 XLT wagon. He told me the overall cost could depend on whether or not I had the factory amp or the standard head. I wasn't aware that there was a "factory" amp. Can anyone shine some light on this? He said if there was an (I'm assuming outboard) amp, then adding a new power amp and speakers would be extremely costly.
Thanks! Tony G
