This thread is for those who are interested sharing ideas to retain ANC functionality while adding a subwoofer to the stock stereo system. (Stock Equinox stereo, 4cyl with ANC)...
Swapping out the door speakers and tweeters is probably not a huge deal, I may even try running my set of Hertz Energy speakers off the factory stereo for now. What I am really interested in is improving the low-end which obviously I will need a subwoofer and amplifier. Ideally I would like to utilize the built-in ANC subwoofer location, and simply drop in a dual voice coil sub. One voice coil will plug straight into the ANC system output, just as it would with the factory ANC sub. The other coil would connect to an aftermarket amplifier which will have a signal from one of the rear door speakers.
Running a power wire, remote turn-on, ground, and signal wires to the rear of the vehicle for the amp is probably not going to be a whole lot more difficult with this vehicle than any other. The real question is how to retain the ANC functionality. I have seen the wiring diagrams for the ANC and sound system; I don't know how to read those and still have questions.
Specifically:
Is there a specific fuse somewhere I can pull to disable ANC? Just pull the stereo system fuse? How bad is the noise without ANC?
Will the ANC system be smart enough to realize that a more efficient and louder subwoofer is in place? (ex. the microphone hears/adjusts the sound output of the sub?) I'm assuming not. I wonder if the new sub would output an overwhelming amount of sound.
How frequently does ANC actually send signals out to the sub? I hear it's only at idle/slow speeds/low RPM. If this is true than it should not interfere TOO much with normal stereo sound output to the sub, correct?
If we decide to somehow keep the entire ANC system fully in tact and install an additional subwoofer in the vehicle, would this interfear with ANC's ability to listen for the vehicle sounds of which it is trying to correct? I'm assuming not since the Pioneer system uses a subwoofer with no issues.
In summary:
This entire topic and discussion could be avoided if I simply drop in another subwoofer and call it a day. It's just that the stock ANC subwoofer location is so ideal for a real sub, and would help keep the cargo area completely clear. Do the benefits of ANC outweigh the benefits of a nice clean real subwoofer installation in this location? Can we have the best of both worlds and install a dual voice coil sub here without causing any major disruptions in the ANC system?
Worst case scenario is I will simply drop another subwoofer/amp combo back there, like the Infinity basslink series, but will probably go out of my way to be sure all connections are 'quick disconnect' type, so that at least we could quickly switch to 'cargo mode' for camp/road trips and other large cargo needs.
