2018-2024 Nissan Kicks Bose Audio Amplifier: Diagnosis and Replacement Guide
This definitive guide covers the Bose audio amplifier in the 2018-2024 Nissan Kicks, focusing on symptoms, replacement, and why programming is not required.
- This amplifier (part # 28061-5RL2A) is ONLY for 2018-2024 Kicks with the 8-speaker Bose audio system, typically on the SR trim.
- Crucially, this amplifier is plug-and-play and does NOT require any programming or a dealer visit for installation.
- The most common symptom of failure is a working radio display but no sound from any of the speakers.
- Replacement is very easy for a DIYer, as the amplifier is located under a simple cover beneath the front passenger seat.
Compatibility: For Bose Systems Only
Critical Compatibility Warning: This amplifier, part number 28061-5RL2A, is exclusively for 2018-2024 Nissan Kicks models equipped with the 8-speaker Bose premium audio system. This system is typically found on the SR trim level. It will NOT work in vehicles with the standard 6-speaker audio system. Before ordering, verify your vehicle has the Bose system (often indicated by a 'Bose' logo on the speaker grilles or head unit) and check the part number on your original amplifier to ensure an exact match.
Symptoms of a Failing Audio Amplifier
When the audio amplifier fails, the radio or infotainment screen may still turn on and appear to function normally, but you'll experience problems with the sound output. Here are the most common signs of a bad amplifier:
- Complete Loss of Sound: The most obvious symptom is no sound from any speaker, even though the radio display shows it's playing music.
- Distorted or Muffled Audio: Sound from all speakers may be heavily distorted, fuzzy, or muffled, making it difficult to understand speech or enjoy music.
- Loud Popping or Static: A sudden loud pop, followed by silence or persistent static, can indicate an internal failure in the amplifier.
- Intermittent Audio / Cutting Out: The sound may cut in and out randomly. This can sometimes be affected by temperature, where the amp works when cold but fails as it warms up.
- Weak Volume or No Bass: The audio may be very quiet even at max volume, or the deep bass frequencies may be completely absent.
Pro Tip: If you are experiencing crackling or static from only one or two speakers, the issue may be a blown speaker rather than the amplifier. If your volume knob is behaving erratically, this is a known issue with the head unit, not the amplifier, and may be addressed by a software update outlined in Nissan TSB NTB20-046G.
Diagnosing the Amplifier
If you suspect the amplifier has failed, follow these simple diagnostic steps:
- Check the Fuses: Before assuming the amp is bad, check the audio-related fuses in the vehicle's fuse panels. A blown fuse is a simple fix. The fuse for the Bose amplifier is typically a 20A fuse located in the interior fuse panel.
- Verify Head Unit Function: Confirm that the radio/infotainment screen powers on, responds to touch, changes stations, and displays media information. If the head unit is frozen or dead, the problem lies there, not with the amplifier.
- Listen for Clues: If you hear static or popping when the radio is on, it suggests the amplifier is receiving power but is failing internally. If there is complete silence but the head unit works, the amplifier is the primary suspect.
Programming and Calibration
Does this amplifier need to be programmed?
No, programming is not required. A technical teardown of this specific amplifier (part number 28061-5RL2A) confirms that it does not have a CAN bus connection or a dedicated microcontroller. In simple terms, it's a 'dumb' amplifier. It does not communicate with the vehicle's main computer network or store vehicle-specific information like the VIN. As long as you are replacing it with an identical part number, the installation is plug-and-play. This makes it an excellent candidate for a simple DIY repair or for replacement with a used unit.
Replacement Guide
Replacing the amplifier is a straightforward job that can be done with basic tools.
- Difficulty: 1/5 (Easy)
- Estimated Time: 15-30 minutes
- Tools Needed: Panel removal tool or flathead screwdriver.
The amplifier is located under the front passenger's seat. In most cases, you do not need to unbolt or remove the seat.
- Slide the front passenger seat all the way back to get the best access to the front of the seat's underside.
- Locate the plastic cover over the amplifier.
- Using a panel tool or being careful with a screwdriver, pry up the plastic cover to expose the amplifier.
- Disconnect the electrical connectors from the old amplifier. There are typically tabs you must press to release each connector.
- The amplifier may be held in place by small bolts or nuts. If so, remove them.
- Install the new amplifier, reconnect the electrical harnesses, and snap the cover back into place.
- Test the audio system to ensure it is working correctly.
Buying a Used Audio Amplifier
Since new aftermarket versions of this Bose amplifier are not available, and new OEM units are very expensive, a used amplifier from a reputable recycler is the most cost-effective solution. Here’s what to look for:
- Match the Part Number Exactly: The only way to guarantee compatibility is to match the part number 28061-5RL2A. Do not install an amplifier from a different vehicle or one for the non-Bose system.
- Inspect the Connectors: Check photos of the used part to ensure the connector pins are straight, clean, and free of any corrosion or damage.
- Look for a Warranty: Reputable sellers of used parts will offer a warranty. This protects you in the rare case that you receive a non-functional part.
- Why Used OEM is a Good Choice: A used OEM amplifier was built by Bose to Nissan's exact specifications for sound quality and durability. It will integrate perfectly with your vehicle's wiring and speakers without any modifications. Given that this part is plug-and-play, there is very little risk in using a tested, guaranteed used unit.
Cost of Replacement
The cost to replace the Bose audio amplifier can vary significantly depending on the source of the part.
| Part Source | Estimated Cost |
|---|---|
| New OEM (Dealer) | $750 - $1,100 |
| New Aftermarket | Not Available |
| Used OEM (Recycled) | $150 - $250 |
| Shop Labor | $75 - $150 |
Frequently Asked Questions (FAQ)
Will replacing the amplifier fix my crackling speakers?
It might, but it's less likely. Crackling is often a sign of a physically damaged or 'blown' speaker cone, especially in the base model Kicks. If the crackling happens on all speakers, the amp could be the cause. If it's isolated to one speaker, the speaker itself is the more likely culprit.
Can I upgrade my standard Kicks audio system to the Bose system by just adding this amplifier?
No. The Bose system uses different speakers (8 total, including headrest speakers) and wiring. Simply adding the amplifier to a non-Bose car will not work and is not a feasible upgrade path.
Is a dealer visit required after installing a replacement amplifier?
No. As this amplifier does not require any programming or configuration, a trip to the dealer is not necessary. It is a plug-and-play part.
My radio screen is blank or frozen. Is the amplifier bad?
No. A blank or frozen screen points to a problem with the AV Control Unit (the head unit/radio itself), not the amplifier. The amplifier's only job is to process and power the sound.
