All stock. Pretty sure amp was bad with only r/r spkr working. Cut both pins on amp, got two front door spkrs working and checks out with bal/fade. Not messing with tweets, as I couldn’t get any sound. But r/r did work, and now both rear door spkrs don’t work. Do the rear spkrs need the amp to work? Or can rear door spkrs work on stock head radio? It’s wired up right according to pin diagrams, however when I took rear doors off to look, both rear speakers have same color wires going to them. Happy I have the front two. Any ideas/advice on the rear ones would be greatly appreciated! Happy Easter!! Peter

Yup. Head unit/amp combined and head unit alone also has weird squiggly noise. I got the two front one’s working for now. End of the month I’ll replace radio. I have two r-Fosgate amps, one for the 4 reg spkrs, and 1 for the 10” sub/box that was in my old Taurus. Prolly blow the 4 stock speakers eventually. Later I’ll get 4 new speakers and wires. Just gotta research crutchfield and find radio that’s compatible with steering wheel controls and pick up wires for the 10’s and amp.
