Sedan vs Wagon – Audio Differences
This model is offered in more than one body style, and audio equipment can vary by configuration. Since no body-style-specific speaker data is listed here, rear speaker placement, optional tweeters, and factory audio packages should be verified by the exact vehicle. Trim and audio package details are the best guide.
What Speakers Fit the 2017 Audi A6?
Aftermarket fitment should start with the factory speaker locations listed above, but diameter alone is not enough. Check mounting depth, bracket fit, connector type, and whether the vehicle has a premium or factory-amplified audio system. This 2017 Audi A6 uses a mix of 4-inch, 5.25-inch, 6.5-inch, and smaller dash or rear-deck speakers, so the best replacement depends on the exact location. Selected audio systems may also include an optional 10-inch subwoofer.
Usually Safe Upgrades
- If your vehicle uses the front door 4-inch mid-range location, a matching 4-inch replacement is the safest starting point.
- If your vehicle uses the front door 5.25-inch full-range location, a 5.25-inch speaker is the closest size match.
- If your vehicle uses the rear door 6.5-inch full-range location, a 6.5-inch speaker is the most straightforward size match.
- If your vehicle uses the dash corner, center dash, or rear deck corner tweeter locations, match the listed 1-inch or .75-inch sizes for the best fit starting point.
- If your vehicle uses the optional rear deck corner subwoofer location, match the listed 10-inch size and verify the enclosure and mounting style before buying.
Check Before Buying
- Confirm the exact speaker location before ordering, since this A6 uses different sizes in the front doors, rear doors, and dash areas.
- Verify mounting depth and frame shape, especially for the smaller dash and tweeter locations.
- Check connector style and any factory bracket or adapter requirements so the replacement matches the original hardware.
- Factory amplifier details should be verified by trim and audio package, since speaker count and amplifier output vary across the listed trims.
- If you are shopping for the optional subwoofer or tweeter locations, make sure the vehicle is actually equipped with that audio package.
Installation Notes
The 2017 Audi A6 uses different speaker layouts depending on audio package, so verify the trim and equipment before ordering parts. Front door locations include a 4-inch mid-range and a 5.25-inch full-range speaker, while the rear doors use a 6.5-inch full-range speaker. Tweeters in the dash, rear doors, rear deck corners, and center dash may be present if equipped, and the center dash may also include a 3.5-inch center channel. If your vehicle has the factory subwoofer, confirm the 10-inch location before planning the upgrade. Panel removal should be done carefully to avoid breaking clips or damaging trim, and wiring should be checked before disconnecting anything. Use the correct harness adapters and mounting adapters for the speaker location, and confirm speaker depth so the new speaker clears the window mechanism and door structure. After installation, test balance, fade, and all channels before reassembling the panels.
Moderate difficulty, since trim-dependent audio equipment, panel removal, and speaker depth checks can affect the installation.
Common Mistakes When Replacing Speakers
The 2017 Audi A6 can vary by trim and audio package, so the most common mistakes happen when buyers assume every car uses the same speaker layout or amplifier setup.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Skipping trim and audio package verification, even though speaker count, amplifier output, and radio setup can change from 10 to 14 speakers.
- Assuming every speaker opening uses the same size and type; the front door, rear door, dash corner, and center dash locations use different sizes, and tweeters or the subwoofer may be present only if equipped.
- Ignoring mounting depth and speaker clearance, which can cause fitment problems even when the diameter looks correct.
- Overlooking connector style and wiring compatibility, especially when factory amplifier details should be verified by trim and audio package.
- Reassembling the panels before testing the new speakers, which can hide wiring issues, channel imbalance, or a missing speaker until everything is already back together.
Generation & Model Family
The 2017 Audi A6 belongs to the C7 (Fourth generation) - Facelift (2016–2018) family. Nearby model years often share similar speaker locations and audio layouts, but exact fitment can vary by trim and audio package – verify before ordering.
Recommended Upgrade Path
The 2017 Audi A6 uses a speaker layout that can vary by trim and audio package, with factory amplifier details needing verification before planning upgrades. Buyers looking for better sound usually get the best results by starting with the front stage, then deciding whether bass, volume, or a cleaner factory-style install matters most.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add matching tweeters if equipped to improve the front soundstage and bring out cleaner vocals and detail. | The front speakers do most of the work for everyday listening, so improving them usually gives the biggest clarity gain. If tweeters are part of the system, upgrading the front stage together helps balance mids and highs more naturally. |
| More bass | If the factory subwoofer is equipped, verify how it is integrated before replacing it or adding an aftermarket subwoofer to build deeper low-end output. | Bass upgrades are most effective when the low-frequency system is planned around the existing audio package. A factory subwoofer may be part of a premium setup, so checking integration first helps you choose the right aftermarket subwoofer path. |
| Louder sound | Properly matched speakers and amplifier integration can improve volume and reduce distortion. Verify factory amp or premium system integration before adding aftermarket amplifiers. | Higher volume is not just about power; it also depends on how well the speakers and amplifier work together. Confirming the factory audio setup first helps avoid mismatched components and keeps the system sounding cleaner at higher levels. |
| Budget improvement | Replace the most-used front door speakers first with same-size replacement speakers and the correct mounting brackets. | A budget-focused upgrade should target the speakers you hear most often. Starting with the front doors gives the most noticeable improvement for the money while keeping the rest of the system unchanged for now. |
| Factory look | Use same-size replacement speakers with the correct mounting brackets and harness adapters for a clean install that preserves the factory wiring and appearance. | This approach keeps the cabin looking original while still improving sound. Using the right brackets and harness adapters helps the installation stay neat and maintain the factory-style layout. |
Mounting Adapters and Wiring
The same nominal diameter does not guarantee a direct mount. Before ordering, confirm:
- Speaker depth: Aftermarket speakers often have larger magnets – measure available depth at each location.
- Mounting brackets: Door locations typically need a bracket or spacer to clear the window regulator and achieve correct mounting depth.
- Wiring harness adapters: Use a plug-and-play harness adapter to preserve factory wiring.
- Tweeter mounting cups: Replacing OEM tweeters may require surface-mount cups or brackets depending on the location.
- Factory or premium amplified systems: If the vehicle has a premium or factory-amplified audio system, confirm how the factory radio, amplifier, and speakers are connected before adding aftermarket amplifiers. Depending on the setup, a line output converter, DSP, integration harness, or professional installation may be needed.
- Connector type: Factory connectors vary by trim and model year – confirm compatibility before splicing or using an adapter.
