Hi Rob and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, is this a fresh/new install? Or has it been in use in the Bronco for some time and this no-sound issue just recent?

Still, are all the speakers wired directly to the Pioneer? ...or is there an amplifier powering the speakers?

Customer: replied 11 months ago.
New install no amp
Expert:  Louie replied 11 months ago.

I understand.

Can we start by reviewing the basics please:

  • always available +12V on the yellow wire'
  • ACC switched +12V on the red wire;
  • the black wire is tied to the metal part/support of the Bronco;
  • clicking sound when testing the speaker wires using a multi-meter;
  • depending on the speakers, the multi-meter would show a reading of 4 ~ 8 Ω per speaker wire pair.

I will double check wiring hopefully will find a meter

A test light would serve the need for the red and yellow wires.

A single 1.5V AA battery may also be used to check the speaker and their wires.

If all of the above checks good, then the Pioneer itself would be suspect.

Consider a RESET. A reset is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed. If have not been done and should you venture to try: press the RESET button.

May have to be done a number of times.

This is very critical - a reset however would not be corrective of an internal hardware concern; but it would be confirmed. In some instances, it may even expose/cause other issues.

Yes please and post back results / observations of the above once tried.
