Coupe vs Sedan – Audio Differences
Different body styles of this model may affect rear speaker placement, cargo-area acoustics, and which factory audio packages were offered. Since body-style-specific speaker data is not listed, equipment can vary by configuration. Factory amplifier details should be verified by trim and audio package before planning upgrades.
What Speakers Fit the 2017 Nissan Altima?
Aftermarket fitment should start with the factory speaker locations listed for the 2017 Nissan Altima, 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. The listed speaker sizes give you a starting point, while trim and audio package can change what is actually installed. Factory amplifier details should be verified by trim and audio package, and selected audio systems may also include dash speakers if equipped.
Usually Safe Upgrades
- If your vehicle uses the front door 6.5-inch location, many aftermarket 6.5-inch full-range speakers are the first place to compare fitment.
- If your vehicle uses the rear door 6.5-inch location, 6.5-inch full-range replacements are another common upgrade path.
- If your vehicle uses the rear deck corner 6 x 9 inch location, 6 x 9 inch full-range speakers are the main size to match.
- If your vehicle has the dash corner 3.5-inch location if equipped, compact 3.5-inch speakers or matching dash components should be checked carefully before buying.
Check Before Buying
- Confirm the exact speaker location in your Altima before ordering, since equipment can vary by trim and audio package.
- Measure mounting depth and opening shape, especially for the 6 x 9 inch rear deck corner and 6.5-inch door locations.
- Verify connector style and any factory bracket or adapter needs so the new speaker matches the original mounting setup.
- If your vehicle has a premium audio system, check amplifier compatibility before choosing replacement speakers.
- If the dash corner speakers are present, confirm whether they are tweeters or center-channel style components before selecting replacements.
Installation Notes
The 2017 Nissan Altima uses different speaker layouts depending on trim, so confirm your exact audio package before ordering parts. Front door speakers are 6.5 inch, rear door speakers are 6.5 inch, and rear deck corner speakers are 6 x 9 inch. Dash corner speakers may also be present if equipped, including a center channel or tweeter. Factory amplifier details should be verified by trim and audio package, since equipment can vary. During installation, remove the door and dash panels carefully to avoid breaking clips or damaging trim pieces. Check speaker depth before mounting, especially in the front doors and rear deck area, because space can be limited behind the panel. Mounting adapters may be needed to match the factory openings, and harness adapters can help preserve the original wiring. If your vehicle has the factory subwoofer, plan the wiring and enclosure work around that equipment. Always test each speaker before reassembling the panels so you can catch wiring or polarity issues early.
Moderate difficulty, since trim-dependent audio equipment and panel access can make the job more involved.
Common Mistakes When Replacing Speakers
The 2017 Nissan Altima can vary a lot by trim and audio package, so the biggest upgrade mistakes usually come from assuming every car has the same speaker layout or factory audio hardware.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Skipping trim and audio package verification, which matters because speaker count, radio setup, and factory amplifier details should be confirmed before ordering parts.
- Choosing speakers without checking mounting depth and connector style, since the listed sizes do not guarantee every replacement will clear the factory opening or match the plug.
- Assuming the dash corner openings are always the same, when the center channel and tweeter are optional and should be treated as if equipped.
- Ignoring the possibility of a factory amplifier on some trims, which can affect signal type and the parts needed for a clean installation.
- Reassembling the door or dash panels before testing the new speakers, because it is much easier to catch wiring or fitment issues first.
Generation & Model Family
The 2017 Nissan Altima belongs to the Fifth generation (L33) - 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 Nissan Altima uses different audio setups depending on trim, so equipment can vary from one model to another. A smart upgrade plan starts with the most-used speakers, then adds bass or amplification only after you confirm the factory audio package. That approach helps you improve sound without overspending or changing the cabin too much.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add the dash corner tweeters if equipped to improve detail and vocal clarity. | The front stage has the biggest impact on clean mids and highs, and the optional tweeters can help sharpen the sound when the rest of the system is already in good shape. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and give the system the low-end output it is missing. | The listed factory speaker setup does not show a subwoofer, so adding one is the most effective way to increase bass without relying on the door speakers to do all the work. |
| Louder sound | Properly matched speakers and amplifier integration can improve volume and reduce distortion. Verify factory amp and premium system integration before adding aftermarket amplifiers. | Higher output works best when the speakers and amplifier are matched correctly, and trim-level audio equipment can vary enough that system checks matter before upgrading power. |
| Budget improvement | Replace the front door speakers first with same-size replacement speakers and the correct mounting brackets. | This gives the best improvement for the money because the front doors handle the sound you hear most often, and you can keep 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 keeps the interior looking original while still improving sound, and it reduces the need for visible modifications to the dash or door panels. |
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.
