I also posted about this on mustang source, and a guy had put one in his F150 and is having the same issues I have. We ended up turning the gain way down and the pop is very muted now and the fm and am radio noise is not noticeable. The added wattage even with the gain reduced really made the pioneer coaxial sing. My son is very happy with the end result. The installer has 10 yrs experience and has installed these units numerous time in different vehicles without any of the issues Ive encountered, so I dont think he is inept.
