Hi all,

I'm installing a new kenwood nav h/u in my 2007 expedition EL limited. The vehicle did NOT come with navigation standard, however it did come with a factory subwoofer. I know that the sub has a factory amp but I'm wondering if there is also a factory amp for the front and rear speakers?

Well,

If anyone ever happens to come across this thread, I manually verified that there is NO stock amplifier in the vehicle for the front or rear speakers, only for the subwoofer. I did the battery pop test and all 4 speakers popped, thereby verifying that there is no amp in the chain.
