Body Style Audio Differences
This 2016 Impreza uses generation-based speaker data, so verify before ordering. Body style can affect factory audio equipment, including speaker count and amplifier setup, even when the main front and rear door locations stay the same. Different body styles may also vary in rear audio packaging and option availability.
What Speakers Fit the 2016 Subaru Impreza?
Aftermarket fitment should start with the factory speaker locations listed above, but diameter alone is not enough. Based on generation data for the 2016 Impreza, the front and rear door openings are listed as 6.5-inch full-range locations, though you should verify before ordering because 2016 speaker location data is shown from the 2015 model year in the same generation. Factory amplifier details should be verified by trim and audio package, since equipment can vary.
Usually Safe Upgrades
- If your vehicle uses the front door location, a 6.5-inch full-range replacement is the starting point for fitment checks.
- If your vehicle uses the rear door location, a 6.5-inch full-range replacement is the starting point for fitment checks.
- If your vehicle has a factory-amplified audio system, confirm speaker impedance and signal handling before choosing replacements.
- If equipped, any premium audio package should be checked for speaker count and wiring differences before ordering.
Check Before Buying
- Measure mounting depth and compare it to the factory opening before buying speakers.
- Confirm the connector style and whether an adapter or harness is needed for your trim.
- Verify the speaker count on your specific trim, since the 2016 Impreza is listed with 4- or 6-speaker systems depending on equipment.
- Check whether your vehicle uses a factory amplifier, because that can affect speaker choice and wiring.
Installation Notes
For the 2016 Subaru Impreza, speaker upgrades should be planned around the generation data, since the available speaker location information is based on 2015 models from the same generation and should be verified before ordering. Front and rear door speakers are listed as 6.5 inch full-range units, while trim audio packages can vary from 4 to 6 speakers. Some trims also show factory amplifier coverage, so wiring should be checked carefully before any installation. Panel removal is usually the first step, and trim clips should be handled gently to avoid damage. Before mounting new speakers, confirm speaker depth and basket clearance behind the door panels. Mounting adapters may be needed to match the factory opening, and harness adapters can help keep the factory wiring intact. If your vehicle has the factory subwoofer, plan the upgrade around the existing bass system and verify signal routing before connecting anything. After installation, test balance, fade, and all speaker channels before reassembling the panels.
Moderate difficulty, since trim variation, factory amplifier coverage, and fitment checks can affect the installation.
Common Mistakes When Replacing Speakers
When shopping for a 2016 Subaru Impreza audio upgrade, the biggest problems usually come from assuming every trim 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, since the available speaker data is based on generation information and should be verified before ordering.
- Assuming every trim has the same audio setup instead of checking the trim and audio package, because speaker count and amplifier details vary across the listed configurations.
- Ignoring factory amplifier details, which should be verified by trim and audio package before choosing replacement speakers or an interface.
- Skipping mounting depth and connector checks, even though the correct size alone does not guarantee the speaker will physically fit or connect properly.
- Overlooking tweeters if equipped, since selected audio systems may include additional components that change the upgrade plan.
- Reassembling the door panels before testing the new speakers, which can make it harder to catch wiring or fitment issues while everything is still accessible.
Generation & Model Family
The 2016 Subaru Impreza belongs to the Fourth generation (GJ) - Facelift (2015–2016) 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 2016 Subaru Impreza uses a 4–6 speaker setup depending on trim, and equipment can vary by audio package. Based on generation data, the front and rear doors use full-range speakers, while factory amplifier details should be verified by trim. That makes the front stage the best place to start for most buyers, especially if you want clearer sound without changing the car’s overall factory feel.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, and add front tweeters if equipped or if your chosen audio package supports them. Focus on a cleaner front stage before moving to the rear speakers. | Clarity usually improves most when the front stage is upgraded first, since that is where vocals and detail are most noticeable. If the vehicle has tweeters in a selected audio system, matching those upgrades can help the highs and mids sound more balanced. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and give the system more low-end output. If the vehicle has a factory bass-focused audio package, verify how it is integrated before adding new bass equipment. | The factory speaker setup is designed for general listening, so a subwoofer is the most effective way to add deeper bass. Checking the existing audio package first helps avoid conflicts with any factory bass tuning or system integration. |
| Louder sound | Use properly matched speakers and amplifier integration to improve volume and reduce distortion. Verify factory amp and premium system integration before adding aftermarket amplifiers or changing the signal path. | Higher output depends on both speaker efficiency and clean power delivery. If the car has a factory amplifier on certain trims, confirming how it is wired and tuned helps the upgrade work smoothly and keeps distortion under control. |
| Budget improvement | Replace the front door speakers first with same-size replacement speakers and the correct mounting brackets. This gives the best improvement per dollar before spending on the rear speakers or additional equipment. | Front speakers carry most of the music you hear, so upgrading them first gives a noticeable improvement without a large budget. Using the correct mounting brackets keeps the install simpler and helps the new speakers fit properly. |
| 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. Matching the factory-style installation method also helps avoid cutting wiring and makes the upgrade easier to service later. |
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.
