Bought 4 SPks and a middle of the road radio. I just use terrestrial radio and my ipod.
My F150 wiring harness had a short so I was already frustrated trying to ring that out.
Went back with questions. They took me pretty fast and there were other customers there, so I really appreciated that. Tech came out to the truck where I had it all laid open, no door panels etc.. Set me straight and explained in expert detail what to do. Later that evening I got it all going. For me it’s all about service after the sale, and that’s what I got from the staff. It’s where I buy my car audio from for years and will continue to do so.
