Key Takeaways
  • This amplifier is ONLY for the standard audio system, not the premium Lexicon system. Verify your system before buying.
  • Match the OEM part number (96370-B1000 or 96370-B1010) to ensure compatibility.
  • No programming or dealer visit is required for installation; it is a plug-and-play part.
  • Common failure symptoms include no sound, distorted audio, or sound that cuts in and out.
The radio amplifier in your Genesis G80 takes the low-level audio signal from the head unit (the screen and controls in your dash) and boosts its power. This stronger signal is then sent to the speakers, creating the sound you hear. In the G80, this specific amplifier is engineered for the 'standard' audio system. It's designed to power a specific number and type of speakers. Without a functioning amplifier, you may experience a complete loss of sound, even if the radio display appears to be working perfectly.

Symptoms of a Failing 2018-2020 Genesis G80 Amplifier

A problem with the factory amplifier can manifest in several ways. Because it's the heart of the audio system's power, its failure is usually obvious. Here are the most common signs that your G80's standard amplifier may be faulty:

  • No Sound From Speakers: The most common symptom is a complete lack of audio from all speakers. The radio or media player on the infotainment screen may look like it's playing normally, but there is no sound.
  • Distorted or Crackling Audio: Sound that is fuzzy, distorted, crackling, or popping, especially at normal volume levels, can point to a failing amplifier. This may happen on all speakers or just a few channels.
  • Audio Cutting In and Out: The sound may work intermittently, cutting out randomly and then returning. This can sometimes be related to loose connections, but it can also indicate an internal failure within the amplifier.
  • Loud Pop or Thump at Startup/Shutdown: A loud noise from the speakers when you turn the car on or off can be a sign of an internal short or other electrical problem in the amplifier.
  • One or More Speakers Not Working: While this can also be a sign of a bad speaker, if an entire section of speakers (e.g., all speakers on the driver's side) stops working, it could be a failed channel within the amplifier.

Pro Tip: Before assuming the amplifier is bad, check the audio system fuses first. A blown fuse can cause a total loss of sound and is a much simpler and cheaper fix. Also, try resetting the infotainment system. On some models, pressing a recessed reset button with a paperclip near the CD slot can resolve temporary glitches.

Known Issues, TSBs, and Recalls

As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) from Genesis or the NHTSA that pertain to the failure of the standard audio amplifier for the 2018-2020 Genesis G80. While other recalls exist for this vehicle, none address this specific component. This suggests that amplifier failure is not a widespread, officially recognized defect but rather occurs on a case-by-case basis due to age, heat, or internal component issues.

Programming and Installation

Does this amplifier need to be programmed?

No. The standard audio amplifier for the 2018-2020 Genesis G80 is a direct replacement part and does not require any special programming, flashing, or dealer intervention after installation. It is a plug-and-play module. The search for programming requirements yielded no evidence that this is necessary, which is typical for base-model amplifiers that are not tied into complex fiber-optic networks or anti-theft systems.

Replacement Procedure

The amplifier is located in the trunk, behind the trim on the left-hand (driver's) side. While professional installation is always an option, a DIY replacement is very feasible for those with basic tools and mechanical skills.

  1. Disconnect the negative terminal from the vehicle's battery.
  2. Access the trunk and remove the necessary trim panels on the driver's side to expose the amplifier and its mounting bracket.
  3. Unplug the electrical connectors from the amplifier.
  4. Unbolt the amplifier or its bracket from the vehicle's chassis.
  5. Install the replacement amplifier by reversing these steps.

Buying a Used Radio Amplifier: What You Need to Know

A used OEM amplifier is an excellent, cost-effective alternative to a new part from the dealer. However, careful purchasing is key. Here’s what to look for:

Warning: This is the most important step. The 2018-2020 Genesis G80 was available with two different sound systems: a standard system and a premium Lexicon surround sound system. The amplifiers are NOT interchangeable. You MUST buy an amplifier that matches your vehicle's original system.

How to Ensure Compatibility:

  • Match the Part Number: The best way to guarantee compatibility is to match the part number. Before ordering, inspect your car's original amplifier and find the number on its label.
  • Standard System Part Numbers: 96370-B1000 or 96370-B1010.
  • Premium Lexicon Part Number (DO NOT BUY): 96370-B1100. This amplifier is for the upgraded 17-speaker Lexicon system and will not work with the standard system's wiring or speakers.

Physical Inspection:

  • Check the Connectors: Ensure the electrical connector ports are clean, with no bent, corroded, or damaged pins.
  • Look for Water Damage: Inspect the casing for any signs of water stains, rust, or corrosion. Water intrusion is a common killer of electronic modules located in the trunk.
  • No Physical Damage: Avoid any units with dented casings, cracked plastic, or broken mounting tabs.

Cost Comparison

Prices can vary based on supplier and availability. Here is a general cost breakdown:

Part TypeEstimated Cost
New OEM (Dealer)$600 - $810
New AftermarketNot commonly available
Used OEM (Recycled)$120 - $200
Shop Labor for Installation$100 - $200

Frequently Asked Questions (FAQ)

How do I know if I have the standard or premium Lexicon audio system?

The easiest way to tell is by looking at your speaker grilles. The premium Lexicon system will have the "Lexicon" brand name on the speaker covers, typically on the door speakers or center dash speaker. If you don't see any branding, you likely have the standard system this amplifier is for.

Will a used amplifier need to be programmed to my car's VIN?

No. For the standard audio system in the G80, the amplifier is a plug-and-play component. It does not need to be coded or programmed to your vehicle's VIN.

Where is the amplifier located in the 2018-2020 Genesis G80?

The amplifier is located in the trunk of the vehicle, mounted behind the trim panel on the left-hand (driver's) side quarter panel.

Can I install this part myself?

Yes, this is a DIY-friendly repair for someone with basic tools. It involves removing some trunk trim, unbolting the old amplifier, and plugging in the new one. The main challenges are carefully removing trim clips without breaking them and ensuring you disconnect the battery first.
