What Speakers Fit the 2020 Jeep Grand Cherokee?
Aftermarket fitment should start with the factory speaker locations listed above, but diameter alone is not enough. Based on generation data for the 2020 Grand Cherokee, the front door uses a 3.5 inch mid-range and a 6 x 9 inch full-range speaker, while the rear door uses a 6.75 inch full-range speaker. Optional equipment can include tweeters, a center channel, and an 8 inch subwoofer if equipped. Check mounting depth, bracket fit, connector type, and whether the vehicle has a premium or factory-amplified audio system before ordering.
Usually Safe Upgrades
- If your vehicle uses the front door 3.5 inch mid-range location, look for a speaker that matches that opening and mounting depth.
- If your vehicle uses the front door 6 x 9 inch location, replacement speakers in that size are the safest starting point.
- If your vehicle uses the rear door 6.75 inch location, choose a speaker built for that diameter and verify depth before buying.
- If equipped with tweeters, use the listed tweeter size for that location and confirm the mounting style first.
- If equipped with the 8 inch subwoofer location, match the factory opening and verify enclosure and power requirements.
Check Before Buying
- Verify the trim and audio package, since speaker count and amplifier details vary across the 2020 Grand Cherokee lineup.
- Confirm whether your vehicle has the optional tweeter, center channel, or subwoofer locations before ordering parts for those positions.
- Measure mounting depth and check the factory connector style, because size alone does not guarantee fit.
- Use the generation-based speaker data as a guide and verify before ordering, since 2020 location data is not fully specific in the source.
Installation Notes
For the 2020 Jeep Grand Cherokee, speaker locations can vary by trim and audio package, so verify the factory layout before ordering parts. Based on generation data, front door speakers may include 3.5-inch mid-range drivers, 6 x 9-inch full-range speakers, and optional 1-inch tweeters, while rear doors use 6.75-inch full-range speakers with optional tweeters. Some setups may also include a center channel, rear pillar tweeters, or an 8-inch subwoofer if equipped. Panel removal is required for most speaker upgrades, so work carefully to avoid breaking clips or scratching trim. Check speaker depth and mounting clearance before installing new drivers, especially in the doors and rear side areas. Mounting adapters may be needed to match the factory openings, and harness adapters help keep wiring changes clean. If your vehicle has the factory subwoofer, confirm enclosure fitment and impedance before replacing it. Always test each speaker after installation to confirm polarity, balance, and system operation.
Difficulty is moderate because trim-dependent audio layouts, panel removal, and fitment checks can add complexity.
Common Mistakes When Replacing Speakers
When shopping for speakers for a 2020 Jeep Grand Cherokee, the biggest errors usually come from assuming every trim shares the same audio layout and skipping verification of the actual equipment on the vehicle.
- 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 amplifier setup can range from 6 to 19 speakers and factory amplifier details should be verified by trim and audio package.
- Ordering replacements without checking mounting depth and speaker size at each location, especially the front door, rear door, dash corner, and rear pillar positions.
- Overlooking connector style and harness compatibility before purchase, which can cause installation delays even when the speaker size looks correct.
- Assuming tweeters, the center channel, or the subwoofer are present on every vehicle instead of confirming whether those speakers are equipped on the specific trim.
- Reassembling the doors or panels before testing the system, which can make it harder to catch wiring, polarity, or speaker-location issues early.
Generation & Model Family
The 2020 Jeep Grand Cherokee belongs to the Fourth generation (WK2) - Second Facelift (2017–2021) 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 Jeep Grand Cherokee uses generation-based speaker data, so equipment can vary by trim and audio package. Some versions include premium amplification and optional speakers, while others use simpler setups. A smart upgrade plan starts with the front stage, then moves to bass, volume, and clean factory-style replacement choices based on your vehicle’s existing system.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door mid-range speakers first, then add or replace the front tweeters if equipped. If your trim has a center channel, verify how it is integrated before changing the front stage. | Clarity comes from the front of the cabin, where most vocals and detail are heard. Improving the front stage usually gives the biggest jump in clean mids and highs. |
| More bass | If the vehicle has the factory subwoofer, check how it is powered and tuned before changing it. You can also add an aftermarket subwoofer system to complement the factory speakers and fill in the low end. | Bass upgrades are most effective when the low-frequency system is matched to the rest of the audio setup. Factory subwoofer details should be verified by trim and audio package. |
| Louder sound | Use properly matched speakers and amplifier integration to improve volume and reduce distortion. If your trim includes a premium audio system, verify factory amp and signal integration before adding aftermarket amplification. | Higher volume without harshness depends on speaker sensitivity, power handling, and how the system is integrated. A mismatched amplifier setup can create more distortion instead of better sound. |
| Budget improvement | Replace the most-used front door speakers first with same-size replacement speakers and the correct mounting brackets. This gives the best value before moving on to the rear speakers or optional channels. | Front speakers carry most of the music detail, so they usually deliver the most noticeable improvement for the money. Starting there keeps the upgrade focused and cost-effective. |
| 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. It also helps the upgrade blend in with the existing cabin design. |
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.
