What Speakers Fit the 2020 Nissan Frontier?
Aftermarket fitment should start with the factory speaker locations listed for this 2020 Frontier, but diameter alone is not enough. Based on generation data, the front door uses a 6 x 9 inch full-range speaker, the rear door uses a 6.5 inch full-range speaker, and the dash corner may include a 2.5 inch tweeter if equipped. Factory amplifier details should be verified by trim and audio package, and speaker count can vary from 4 to 10 depending on configuration.
Usually Safe Upgrades
- If your vehicle uses the front door 6 x 9 inch location, look for aftermarket full-range speakers in that size and confirm mounting depth before ordering.
- If your vehicle uses the rear door 6.5 inch location, choose full-range speakers that match the opening and check connector style and clearance.
- If your vehicle has the dash corner tweeter location, a 2.5 inch tweeter upgrade may fit if equipped, but verify the factory layout first.
- If your vehicle is equipped with a factory amplifier, make sure the replacement speakers are compatible with the system’s output and wiring requirements.
Check Before Buying
- Verify the exact trim and audio package, since speaker count and amplifier setup vary across the Frontier lineup.
- Confirm whether the dash corner tweeter location is present before buying any tweeter kit.
- Measure mounting depth, grille clearance, and bracket style so the new speakers will physically fit the factory openings.
- Check the connector type at each location so you know whether adapters or wiring changes may be needed.
- Use the generation-based speaker data as a guide and verify before ordering, since the 2020 location data is noted as based on 2017 information.
Installation Notes
The 2020 Nissan Frontier uses speaker layouts that can vary by trim, so verify your exact audio package before ordering parts. Based on generation data, front door locations use 6 x 9 inch full-range speakers, rear door locations use 6.5 inch full-range speakers, and dash corner tweeters may be present if equipped. Some trims also show different speaker counts, so factory amplifier details should be verified by trim and audio package. Plan on removing interior panels carefully and working around clips and trim fasteners without forcing them. Check speaker depth and magnet clearance before final installation, especially in the front doors. Mounting adapters may be needed to match the factory openings, and harness adapters can help keep the wiring clean and reversible. If your vehicle has the factory subwoofer, confirm the signal path before adding or replacing bass equipment. Always test each speaker before reinstalling the panels so you can catch polarity or connection issues early.
Moderate difficulty, with trim-dependent wiring and fitment details that should be verified before starting.
Common Mistakes When Replacing Speakers
When shopping for audio upgrades for the 2020 Nissan Frontier, the biggest errors usually come from assuming every truck is wired the same and skipping a few fitment checks.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Ignoring trim and audio package differences, since speaker count and radio equipment can vary from 4 to 10 speakers depending on the setup.
- Assuming the dash corner tweeters are always present, when they should be treated as if equipped and verified before ordering.
- Skipping mounting depth and connector checks, which can lead to parts that do not match the factory opening or wiring.
- Not verifying factory amplifier details by trim and audio package, since amplifier equipment is not universal across the lineup.
- Reassembling everything before testing the new speakers or wiring, which can hide a wiring or polarity problem until the panels are already back on.
Generation & Model Family
The 2020 Nissan Frontier belongs to the Second generation (D40) - Facelift (2009–2021) 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 2020 Nissan Frontier uses different audio setups depending on trim, so equipment can vary. Based on generation data, the front stage is the best place to start for most buyers, especially if you want clearer vocals and stronger detail. If you are planning a bigger system, verify factory amplifier details by trim and audio package before ordering.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add dash corner tweeters if equipped, using quality components that improve midrange detail and high-frequency response. | The front stage carries most of the music you hear, and the optional tweeters can help sharpen vocals and instrument detail when they are part of the vehicle's audio setup. |
| More bass | Add an aftermarket subwoofer system to complement the factory speakers and fill in the low end without relying on the stock door speakers for deep bass. | A dedicated subwoofer is the most effective way to add low-frequency output and reduce strain on the factory speakers. |
| Louder sound | Use properly matched speakers and amplifier integration to improve volume and reduce distortion, and verify factory amp or premium system integration before adding aftermarket amplifiers. | Higher output works best when the speakers and amplification are matched correctly, especially on trims where factory audio equipment can vary. |
| Budget improvement | Replace the front door speakers first with same-size replacement speakers and the correct mounting brackets, then upgrade the rear speakers later if you want more overall balance. | The front speakers do the most work in daily listening, so this gives the biggest improvement for the money. |
| 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 interior looking original while still improving sound quality and making future service easier. |
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.
