Popps

The rear left speaker in the door of my 2010 Lariat with the Sony Nav system is flaky, some days it works, others it's silent. When it goes on the fritz I can run the speaker diagnosis by holding down 6 and 3 preset buttons and when it tests that speaker there's no noise so clearly a connection problem or something. Before I let the monkeys rip into it I'd like to check something simple like the speaker terminal connections but how do I access them, is it hard to take the necessary door trim off? Am I best advised to have them do it in case I break off any plastic tabs or anything?

It's really easy to get into the speakers. I did it this last weekend when I replaced my speakers. Here's a link (I hope) to a forum page that shows how. https://www.f150forum.com/f74/how-re...s-09-a-149551/

Also do a YouTube search on "F150 speaker Removal". It shows both front and back. It's REALLY easy.
