I checked both the front map light box and in the rear headliner for mic's associated with Active noise cancellation (ANC) and no joy on either. There is a mic in the maplight box but it's hardwired with no way to "unplug" it. I have a 2017 GT350 with a shaker system minus the sub. I'm getting quite a bit of feedback in the speakers after upgrading them and everything I've researched is pointing the similar issues ecoboost's were having with the ANC.
Currently my setup is
1. Highlevel inputs tapped after the factor amp outs, running to a JL Audio Fix 86
2. from the Fix 86 RCA's running to 1-4channel amp and 1-mono amp
3. Speaker wire running from the four channel amps to rear coax speakers, and speaker wire running to a crossover for the the front speakers. Front speakers are - 6.5" lower mids (low crossover), 3.5" factory mids, 1" JBL tweeters.(high crossover, split between the 3.5"s and tweeters)
I was running a LC7i but had feedback coming back from the speakers so I switched to the Fix86 in hopes that it would clean up the signal, but no joy.
I spoke with Jesse from [MENTION=20927]OEMRadio[/MENTION] and waiting to get the harness from him, but I've tried everything else to get rid of the crappy signal being fed through the speakers.
I opened up the dash and noticed that the speaker lines coming out of the head unit (HU) have duct tape around them from factory. I opened up the duct tape and the speaker wire is taped (no spliced) to another open silver wire (I'm assuming the ground?). It seems like a bad way to introduce feedback signal immediately after the HU and I'm not sure why the factory would use this as their method for wiring.
At this point the only things I haven't eliminated are the HU itself being bad, the crappy wiring job from factor from the HU to the factory amp, the factor amp itself being bad, AND/OR the signal processing being done by the factory amp/HU.
At this point I just want to figure out what is causing the issue, because I've spent so much on an aftermarket system but can't enjoy it with this constant signal/feedback being pumped through the speakers as well. :shrug:
