Head unit no longer pushing audio to front speakers?
Hi all,
I recently tried swapping my aftermarket amp for something a little more powerful since I was underpowering my current speakers. I unhooked the battery, switched out the fuse, and took the wires from my current amp to the new one (P600x4). During the gain leveling I noticed that the front channels weren't delivering any audio to the amp (speakers weren't hooked up yet). I left the gain low and hooked the rest back up. As expected, only the rear speakers produced music, but the front driver side speaker buzzed softly (passenger was silent). Altering the gain altered the volume of the buzzing.
I took a good, spare speaker and just hooked it up directly to the head unit (factory nav) output using my Metra harness (72-5600) for both the driver and passenger side. It produced the same results as the amp did. I also just hooked the amp directly to my phone using an RCA->3.5mm and each speaker worked perfectly fine, so it obviously isn't the amp doing it.
For some reason it appears that my head unit no longer delivers audio to the front speakers (the subs still work without issue, I have never touched those). I would simply pull the sound from the rears and push it to the fronts, but then Sync would only play through the driver sub, which isn't exactly workable. Does anyone have any clue what could be going on? Is there a fuse specifically for the front door audio?
Thanks.
