I need to know where exactly the ANC module is located in a 2013 acura tl 3.5L and how to get to it. Thanks

What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
First identify the factory audio package and describe the actual symptom: unwanted bass or booming, a turn-on problem, or simply a request to locate ANC. Record which factory speaker outputs feed the LC2i and have the installer compare its power, ground, signal inputs, and turn-on arrangement with the AudioControl manual. If unwanted sound began after the aftermarket installation, have the installer compare operation with the added amplifier safely disabled. A change would narrow the investigation to the added system or its interaction with the factory system; it would not prove that ANC alone is responsible. Before unplugging microphones or altering factory wiring, obtain the Acura wiring and component-location information for this exact audio package. Match connector identity and pin numbers, not wire colors alone. Correcting a verified installation issue or using a confirmed compatible integration method gives a clearer path than cutting wires experimentally.
Guidance references and applicability
AudioControl LC2i user manual: https://www.audiocontrol.com/downloads/car/current/lc2i/lc2i-user-manual.pdf Manufacturer reference for LC2i connections, signal-sensing turn-on, and setup. It is not an Acura ANC component-location or wiring reference. The suggested comparison with the added amplifier disabled is a diagnostic isolation step, not a manufacturer-verified ANC bypass. Exact Acura service information is still required before modifying factory connections.
I'm assuming your wanting to install an aftermarket radio system. If this is the case see below.
It is fully integrated into the audio amplifier unit. To completely disable or bypass the ANC system you'll need to access the factory amplifier located in the trunk.
1. Remove the spare tire cover panel to expose the audio amplifier mounted on the driver's side or forward trunk wall area. If I am wrong let me know.
2. The factory amplifier (it's likely labeled Pioneer) should be visible. You should see multiple a multi-pin wiring harnesses plugged into it (typically a 20-pin and a 14-pin connector).
3. Because the ANC runs through the amplifier connections, either unplug the specific pins responsible for the ANC microphone inputs or use a specialized line output converter/bypass method.
Alternatively, you can disconnect the headliner microphones. This is the preferred non-invasive shortcut used by most technicians to bypass ANC without cutting amplifier wires.
They are directly at the headliner (front map light console and rear dome light assembly).

The amp is in trunk on passengers side and which wires are they. I do have lc2i hooked up

Locate the 14-pin connector on the amplifier. Locate the Yellow/Black and Light Green/Red wires if you are tapping the factory sub-line for a Line Output Converter.

Discussion summary
ANC MODULE?
The owner of a 2013 Acura TL 3.5L asked where the active noise cancellation module was located. A contributor discussed the factory amplifier and possible bypass approaches. The owner corrected the amplifier location to the passenger side of the trunk and confirmed that an AudioControl LC2i was installed. A later reply supplied wire colors, but the discussion did not verify a connector diagram or report a successful ANC bypass.
Reported outcome: No verified ANC location, completed bypass, or corrected audio symptom was reported.
The factory audio package and the reason for disabling ANC were not established. The amplifier location was disputed within the replies. The claimed integration of ANC into the amplifier and the supplied wire colors remain unverified.
