Vehicle and Audio System Specifications
This block helps identify the vehicle and its audio system configuration for fitment decisions.
Body Style Audio Differences
This 2017 Subaru Impreza uses the same general audio layout across the model, but equipment can vary by trim and audio package. Factory speaker counts range from 4 to 6, with 6 x 9 inch front speakers and 6.5 inch rear speakers listed. Factory amplifier details should be verified by trim and audio package.
What Speakers Fit the 2017 Subaru Impreza?
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 audio package before ordering. This 2017 Subaru Impreza uses 6 x 9 inch front speakers and 6.5 inch rear speakers in the listed factory layout, and trim equipment can vary from 4 to 6 speakers. Selected audio systems may also include a factory subwoofer if equipped.
Usually Safe Upgrades
- If your vehicle uses the front 6 x 9 inch location, look for aftermarket speakers that match that opening and confirm depth before purchase.
- If your vehicle uses the rear 6.5 inch location, choose speakers sized for that position and verify the mounting pattern and connector style.
- If your trim uses the 4-speaker layout, confirm which factory locations are present before shopping for replacements.
- If your trim uses the 6-speaker layout, check whether the vehicle has any premium audio equipment that could affect fitment.
Check Before Buying
- Measure the available mounting depth at each speaker location before ordering.
- Confirm the factory connector shape and whether an adapter is needed for the new speakers.
- Verify the trim and audio package, since speaker count can vary by configuration.
- Check whether the vehicle has any factory subwoofer if equipped, since that can change the overall audio setup.
Installation Notes
The 2017 Subaru Impreza uses different factory speaker layouts depending on trim, so confirm your exact audio package before ordering parts. Front locations are listed as 6 x 9 inch and rear locations as 6.5 inch, with total speaker count varying from 4 to 6. Plan on removing interior panels carefully and working around clips and fasteners without forcing them. Wiring should be checked before connection, since factory amplifier details should be verified by trim and audio package. Use the correct harness adapter for the vehicle side and the proper mounting adapters for the speaker openings, especially if you are changing speaker size or depth. Speaker depth should be measured before installation to avoid interference with the door or trim panel. If your vehicle has the factory subwoofer, match the replacement parts to that system as well. After installation, test balance, fade, and all speaker locations before reassembling the panels.
Moderate difficulty, since trim-dependent speaker layouts and careful panel removal can affect the installation.
Common Mistakes When Replacing Speakers
The biggest audio-fit mistakes on a 2017 Subaru Impreza usually happen when buyers assume every trim shares the same speaker setup or skip basic fit checks before ordering parts.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Assuming every trim has the same speaker count when this model ranges from 4 to 6 speakers depending on trim and audio package.
- Ignoring trim and radio package differences, especially when factory amplifier details should be verified by trim and audio package.
- Skipping mounting depth and connector checks before choosing replacement speakers, which can lead to fitment problems even when the size looks correct.
- Overlooking tweeters if equipped, since some audio setups may include separate high-frequency speakers that change the install plan.
- Not testing the system before reassembly, which can leave wiring issues or speaker polarity problems hidden until everything is back together.
Generation & Model Family
The 2017 Subaru Impreza belongs to the Fifth generation (GK) (2017–2019) 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 Subaru Impreza offers a straightforward starting point for audio upgrades, with equipment that can vary by trim and audio package. Some versions use a 4-speaker setup while others include 6 speakers, so the best path depends on your exact configuration. A smart upgrade plan starts with the front stage, then adds bass or amplification as needed.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front speakers first, and add tweeters if equipped or if your chosen audio system supports a front-stage upgrade. | Front speakers carry most of the vocals and detail, so improving them usually gives the biggest jump in clarity and overall sound balance. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and fill in the low end. | A dedicated subwoofer handles bass more effectively than door speakers, giving the system more depth without forcing the factory speakers to do extra work. |
| 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. | More output only helps when the speakers and amplification are matched correctly, and integration checks help avoid problems with the existing audio setup. |
| Budget improvement | Replace the front doors first with same-size replacement speakers with correct mounting brackets. | The front doors are the most-used speakers in daily listening, so upgrading them first gives the best value for a modest budget. |
| 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, and it helps the installation stay neat and reversible. |
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.
