Vehicle and Audio System Specifications
This block helps identify the vehicle and its audio system configuration for fitment decisions.
Body Style Audio Differences
This 2007 Subaru Impreza uses the same core speaker layout across the available body styles, but equipment can vary by trim and audio package. Rear speaker placement, speaker count, and factory amplifier setup may differ between versions, so verify the exact vehicle before choosing upgrades or replacement parts.
What Speakers Fit the 2007 Subaru Impreza?
Aftermarket fitment should start with the factory speaker locations listed above, but diameter alone is not enough. This 2007 Subaru Impreza uses 6.5-inch full-range speakers in the front and rear doors, while trim and audio package can change the total speaker count. Factory amplifier details should be verified by trim and audio package, and selected audio systems may also include additional equipment. Before buying, confirm mounting depth, connector style, and whether your vehicle matches the listed audio setup.
Usually Safe Upgrades
- If your vehicle uses the front door location, a 6.5-inch full-range replacement is the starting point for fitment.
- If your vehicle uses the rear door location, a 6.5-inch full-range replacement is the starting point for fitment.
- If your vehicle is one of the trims listed with 4 speakers, focus on the door speaker locations shown in the factory data.
- If your vehicle is one of the trims listed with 6 speakers, verify the full audio package before choosing replacements.
Check Before Buying
- Confirm the exact trim and audio package, since speaker count and amplifier equipment can vary.
- Measure mounting depth and check the factory bracket or adapter requirements before ordering.
- Verify the connector type at each speaker location so the replacement matches the vehicle wiring.
- If your vehicle has a factory-amplified system, make sure the replacement speakers are suitable for that setup.
Installation Notes
The 2007 Subaru Impreza uses 6.5-inch full-range speakers in the front and rear doors, while trim and audio equipment can vary from 4 to 6 speakers overall. Before starting, confirm the exact trim and audio package, since factory amplifier details should be verified by trim and audio package. Remove the door panels carefully and keep track of clips and fasteners so the trim goes back together cleanly. Check speaker depth and mounting space before ordering parts, because some replacements may need mounting adapters or spacer rings to clear the window track and door structure. A speaker harness adapter can help avoid cutting the factory wiring, and it is a good idea to test polarity and speaker function before fully reassembling the doors. If your vehicle has the factory subwoofer, plan the upgrade around that system separately. Take your time with wiring and panel fitment so the final install sounds clean and stays secure.
Moderate difficulty, mainly because trim, amplifier, and speaker layout can vary by configuration.
Common Mistakes When Replacing Speakers
When shopping for speakers or an upgrade on the 2007 Subaru Impreza, the biggest errors 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.
- Ignoring trim and audio package differences, since speaker count can range from 4 to 6 and amplifier details should be verified by trim.
- Assuming tweeters are part of every setup; this model does not list tweeters, so only plan for them if equipped on a specific vehicle.
- Skipping mounting depth and connector checks before ordering replacement speakers, which can lead to fitment problems even when the size is correct.
- Not testing the system before reassembly, which can leave a wiring or polarity issue hidden until everything is back together.
- Overlooking factory amplifier details on trims where an amp may be present or optional, since the audio layout can change the parts you need.
Generation & Model Family
The 2007 Subaru Impreza belongs to the Second generation (GD) - Second Facelift (2006–2007) 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 2007 Subaru Impreza uses a simple factory speaker layout, but equipment can vary by trim and audio package. That makes the best upgrade path depend on whether you want cleaner detail, stronger low end, or a more complete system change. Start with the front stage for the biggest everyday improvement, then build out from there based on your budget and goals.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add front tweeters if equipped or if your chosen setup supports them. | Cleaner mids and highs usually come from the front stage, where most of the detail is heard. Focusing there gives the most noticeable improvement in clarity without needing a full system overhaul. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and tune it to blend with the rest of the system. | A dedicated subwoofer handles the low end that door speakers cannot reproduce well. This is the most effective way to add bass without relying on the factory speaker set to do everything. |
| 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 only helps if the system is matched correctly. Checking the existing audio package first helps avoid integration issues and keeps the upgrade focused on clean, usable volume. |
| Budget improvement | Replace the front door speakers first with same-size replacement speakers and the correct mounting brackets. | The front doors are the most-used speakers in daily driving, so upgrading them first gives the best value. This approach improves the sound where it matters most while keeping the project affordable. |
| 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 keeps the interior looking original while still improving sound quality. Using the right brackets and harness adapters also 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.
