Aftermarket Amp and Sub installed on a C7, 1LT
Afternoon,
I had a local audio shop install an amp and subwoofer to my 15 C7 1LT "no previous subwoofer". Install was uneventful but the product is terrible. All they are getting is a constant noise from the sub, which is worse when operating the car. They believe the problem is the noise cancelling subsystem of the Bose system is causing the problem and recommending to "turn off the noise cancelling feature", which appears not to be a easy thing to do.
With that said.....has anyone installed an amp and sub to their C7 and experienced the same problem and how was it fixed. Thanks in advance.

If you're just looking to disable Bose's installed noise cancellation you can do that from the head unit under settings. You're looking for Bose Audiopilot, switch it off. That will disable all of the active noise cancellation from the system. Not sure how it would help your situation, but hey, if the shop thinks it will work then why not try it?

Thanks for the head unit information. Will check my audio when I get home. I have the base unit audio system, so hopefully it has the same capability.

Not an electronics guy, but based on everything I read it seems reasonable based on how the noise cancellation system works! Will let everyone know how it goes!

mdiiulio,
Looked at the head unit and sure enough....the Bose AutoPilot feature is not listed under the Radio setting. Well that tells me either the 1LT doesnt have the noise cancelling technology, or the base audio system doesn't have the capability of turning it on/off via the head unit. Thanks for the information. Will have to determine one or the other!

Just looked at the infotainment manual... Has "Bose Audiopilot (if equipped)" Looks like 1LT audio may not have it. But then again, the regular manual also has a "LATCH (if equipped)" section for child seats, yet exactly 0.000 corvettes are equipped with them. So there's that

Look under the Menu tab on the far right of the main audio screen

I got part of the schematics for the 1LT, that shows the speaker wire colors for each speaker. Right now the audio shop is tapped into one of the back speakers which I have now learned is the wrong one. It has to be one of the woofer speakers in the doors. Hopefully tomorrow I will have the other two parts that show which pins in the 16 pin plug attached to the factory amp control the noise canceling mics so I can get them turned off. So I think I'm heading in the right direction. Will keep you updated. I appreciate the help and assistance!!!!!

So the noise canceling mic is on each door panel. You'll need to remove the door panel on each side and unplug the wire going to the mic. Its easy to find its the only wire that goes to anything that resembles a mic. That will solve the "white noise" problem. Turning it off at the head unit will not help (I've tried it).
BTW save yourself some time and frustration. Purchase some type of Signal leveling product (I used a BitOne but there are others that work just as well for cheaper). Pull the high signal inputs from the Bose Amp. The sound is much better but lets face it. It will never sound as good as a aftermarket head unit which in our case is not obtainable.
