2021-2024 Genesis G80 Audio Amplifier: Fixing No Sound & Lexicon System Failures
A complete guide to diagnosing common audio problems, replacing the Lexicon amplifier, and finding the right used part for your G80.
- This amplifier is ONLY for G80 models with the Lexicon Premium Audio system; it will not work in a base model.
- A replacement amplifier does NOT need to be programmed by a dealer; it is a plug-and-play part.
- Before replacing the amplifier for a 'no sound' issue, always try a system reset by disconnecting the battery for 15 minutes.
- When buying a used unit, match your original part number (96370-T1500 or 96370-T1600) and inspect it for signs of water damage.
Symptoms of a Failing G80 Amplifier
A problem with the Lexicon amplifier can manifest in several ways. Before assuming the amplifier is bad, it's important to perform a soft reset of the infotainment system, as software glitches can sometimes mimic hardware failure. If problems persist, you may be dealing with a faulty amplifier.
- Complete Loss of Sound: The most common symptom is a total absence of audio. The infotainment screen may appear to be working correctly, but no sound comes from any speaker for radio, media, or phone calls.
- Popping, Crackling, or Distorted Audio: Loud pops or static, especially when the system starts or the volume is adjusted, can indicate failing internal components in the amplifier.
- Intermittent Audio: The sound may cut in and out randomly while driving. This can be caused by a faulty connection or the amplifier overheating and temporarily shutting down.
- Loss of Specific Channels: You might lose bass if the subwoofer channels fail, or notice that sound is only coming from one side of the car.
- Parasitic Battery Drain: In some rare cases, a malfunctioning amplifier can fail to shut down properly when the car is turned off, leading to a parasitic draw that drains the battery overnight.
Important: Many audio issues can be caused by software glitches. Before replacing hardware, try a system reset by holding the 'MAP' and 'SETUP' buttons, or by disconnecting the car's negative battery terminal for 15 minutes to perform a 'hard reset'. Some owners have also had success restoring sound by accessing the system's engineering mode.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) issued by Genesis for the audio amplifier itself in the 2021-2024 G80. However, a related issue is worth noting:
- NHTSA Recall 26V019000: This recall affects some 2025-2026 Genesis models, including the G80. It addresses a software error in the Audio/Video/Navigation (AVN) head unit that can cause the instrument panel and center display to intermittently reboot. While this is a head unit issue, not an amplifier failure, the symptom includes a temporary loss of audio and display functions. The fix is a software update, often delivered Over-The-Air (OTA).
Pro Tip: The absence of a recall doesn't mean a part doesn't fail. Forum discussions for Genesis vehicles show that amplifier failure is a known issue on previous generations, suggesting a potential pattern of weakness for this component.
Programming and Installation Requirements
Is Programming Required?
No. The audio amplifier for the 2021-2024 Genesis G80 does not require any special programming, flashing, or VIN matching after installation. It is a plug-and-play component. This makes it a straightforward replacement for DIY mechanics and independent repair shops, with no dealer visit necessary for software configuration.
Replacement Overview
The amplifier is located in the trunk, on the driver's side, behind the trunk liner. Replacement is a relatively simple process:
- Disconnect the vehicle's negative battery terminal.
- Remove the trunk floor covering and any cargo nets.
- Carefully unclip and remove the driver's side trunk liner to expose the amplifier.
- Unplug the electrical connectors from the amplifier.
- Remove the bolts (typically 10mm) securing the amplifier bracket to the vehicle body.
- Install the replacement amplifier by following the steps in reverse.
Buying a Used 2021-2024 G80 Amplifier
A used OEM amplifier is an excellent way to save money compared to a new part from the dealer. However, careful verification is essential to ensure you get the right part.
1. Confirm Your Audio System
Warning: This amplifier is ONLY for vehicles equipped with the Lexicon Premium Audio system. It will not work with the standard base audio system, nor can it be used to upgrade a base system. Before ordering, confirm your vehicle has the Lexicon system by checking for 'Lexicon' branding on the speaker grilles or in the audio settings menu of your infotainment system.
2. Match the Part Number
Always match the part number on your original amplifier to the number on the used part you are buying. The two known part numbers for this vehicle are:
- 96370-T1500
- 96370-T1600
While these may be interchangeable or represent minor production updates, the safest method is to buy a used unit with the exact same number as your failed one.
3. Physical Inspection
When buying a used amplifier, inspect the photos carefully or check the part in person if possible. Look for:
- No Water Damage: The trunk is a common area for water leaks. Look for any signs of corrosion, water stains, or a white, chalky residue on the metal casing or inside the connector pins. Water intrusion is a common cause of failure for trunk-mounted electronics.
- Intact Connectors: Ensure the plastic connectors and all pins are straight and undamaged.
- Undamaged Casing: Avoid units with heavy dents or damage, which could indicate they came from a vehicle involved in a severe collision.

Frequently Asked Questions (FAQ)
Does a replacement amplifier need to be programmed by the dealer?
No, the 2021-2024 G80 audio amplifier is a plug-and-play part and does not require any programming or dealer intervention after installation.
Where is the audio amplifier located in the 2021-2024 Genesis G80?
The amplifier is located in the trunk on the left-hand (driver's) side, behind the carpeted trim panel.
Can I upgrade my standard G80 audio system to the Lexicon system by just installing this amplifier?
No. The Lexicon system uses a different wiring harness, different speakers, and additional components. This amplifier is not compatible with the base audio system and cannot be used for an upgrade.
My sound stopped working. Is it definitely the amplifier?
Not necessarily. Before buying a new amplifier, try resetting the infotainment system. A 'hard reset' by disconnecting the negative battery terminal for 15 minutes often resolves software glitches that cause a loss of sound. Also, be sure to check the fuses related to the audio system.
