Body Style Audio Differences
This 2014 Subaru Legacy uses the same core speaker layout across the model data we have, with 6.5-inch full-range speakers in the front and rear doors. Because body-style-specific audio details are not listed, equipment can vary by body style, trim, and audio package, especially for amplifier-equipped systems.
What Speakers Fit the 2014 Subaru Legacy?
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. On this 2014 Subaru Legacy, the listed factory locations are 6.5-inch full-range speakers in the front and rear doors, while trim equipment can vary from 4 to 9 speakers depending on the audio package. Selected audio systems may also include a factory amplifier, so verify the exact setup before ordering.
Usually Safe Upgrades
- If your vehicle uses the front door location, a 6.5-inch full-range speaker is the starting point for replacement shopping.
- If your vehicle uses the rear door location, a 6.5-inch full-range speaker is the starting point for replacement shopping.
- If your trim has the 9-speaker audio package, confirm amplifier compatibility before choosing replacement speakers.
- If equipped with a premium audio system, match the replacement speaker to the factory mounting and wiring style before purchase.
Check Before Buying
- Confirm the speaker location and size for your exact vehicle before buying, since the Legacy can have different speaker counts by trim.
- Measure mounting depth and check the factory opening, because a 6.5-inch speaker can still vary in fit from one design to another.
- Verify connector type and any adapter needs so the new speaker can be wired correctly.
- Check whether your trim uses the 9-speaker system with a 440W amplifier, since that can affect speaker selection and system balance.
Installation Notes
The 2014 Subaru Legacy uses 6.5-inch full-range speakers in the front and rear doors, so installation usually starts with careful door panel removal and a check of the factory wiring before anything is disconnected. Speaker depth should be measured before ordering new speakers, since clearance can vary by trim and audio package. Some setups may need mounting adapters and harness adapters to help the new speakers fit and connect cleanly. Factory amplifier details should be verified by trim and audio package, especially on higher audio systems, because speaker count and amplification can differ from one version to another. If your vehicle has the factory subwoofer, plan the upgrade around that system as well. Take care not to damage clips, switches, or wiring during removal, and test each speaker after installation to confirm correct polarity and clean operation. Because equipment can vary, it is smart to compare the vehicle’s audio package with the replacement parts before starting.
Moderate, because trim-dependent audio equipment and speaker depth should be verified before installation.
Common Mistakes When Replacing Speakers
The 2014 Subaru Legacy can vary a lot by trim, so the safest upgrade plan is to verify the exact audio setup before ordering parts.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Skipping trim and audio package checks when speaker count can range from 4 to 9 and factory amplifier details should be verified by trim and audio package.
- Assuming every model uses the same speaker setup instead of confirming the front and rear door 6.5-inch full-range locations on the specific vehicle.
- Ignoring mounting depth and connector style, which can cause fitment problems even when the speaker size looks correct on paper.
- Overlooking factory amplifier differences on trims where a 440W system is listed, which can affect speaker choice and wiring needs.
- Reassembling the doors before testing the new speakers and radio functions, which can hide wiring or polarity issues that are easier to fix first.
Generation & Model Family
The 2014 Subaru Legacy belongs to the Fifth generation (BM) - Facelift (2013–2014) 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 2014 Subaru Legacy uses a straightforward factory speaker layout, but equipment can vary by trim and audio package. Some trims include a factory amplifier, while others use simpler systems, so the best upgrade path depends on the starting setup. The options below focus on the most practical improvements for clearer sound, stronger bass, and a cleaner factory-style result.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add front-stage tweeters if equipped or if your chosen audio setup supports them. This gives the biggest improvement in vocals, detail, and overall sound balance. | The front stage carries most of the music you hear, so improving it usually delivers the clearest change in sound quality. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and relieve the door speakers from trying to handle low bass. If your trim includes a factory amplifier or premium audio package, verify how it integrates before choosing the sub and amplifier setup. | A dedicated subwoofer adds low-end impact that the door speakers alone cannot provide, especially in a factory-based system. |
| Louder sound | Properly matched speakers and amplifier integration can improve volume and reduce distortion. Before adding aftermarket amplifiers, verify factory amp and premium system integration so the new gear works correctly with the existing audio setup. | Higher output only helps when the speakers and amplification are matched well, otherwise distortion can increase instead of sound quality. |
| Budget improvement | Replace the front door speakers first using same-size replacement speakers with correct mounting brackets. This is the most cost-effective way to improve the sound where it matters most. | Front speakers handle the majority of the listening experience, so upgrading them first gives the best value 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 cabin 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.
