Crossover vs SUV – Audio Differences
For this 2009 Forester, body style can affect how factory audio packages are arranged, but the database does not provide body-style-specific speaker data. Speaker count ranges from 4 to 6 depending on trim, and some trims may include an optional amplifier. Tweeters are listed if equipped.
What Speakers Fit the 2009 Subaru Forester?
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. This 2009 Subaru Forester uses 6.5-inch full-range speakers in the front and rear doors, and front tweeters are listed if equipped. 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 speaker is the factory size to compare against for replacement options.
- If your vehicle uses the rear door location, a 6.5-inch full-range speaker is the factory size to compare against for replacement options.
- If your vehicle has the front tweeter location, a 1-inch tweeter may be present if equipped, so match the opening and system layout before buying.
- If your vehicle is one of the trims with a 6-speaker audio setup, confirm how the factory tweeters are integrated before choosing replacement speakers.
Check Before Buying
- Measure the mounting depth and check for any factory bracket or adapter requirements before ordering.
- Confirm whether your Forester has the 4-speaker or 6-speaker audio setup, since speaker count varies by trim.
- Verify connector style and wiring before purchase, especially if the vehicle has a factory amplifier on some trims.
- Check whether the front tweeters are installed in your vehicle, since they are listed as optional equipment.
Installation Notes
The 2009 Subaru Forester uses 6.5 inch full-range speakers in the front and rear doors, and front tweeters may be present if equipped. Speaker count can vary by trim, so confirm the audio package before ordering parts. Installation usually starts with careful panel removal, then disconnecting the factory speaker wiring before removing the original speakers. Check speaker depth and mounting space behind each door panel, since clearance can affect fitment. Mounting adapters may be needed to match the factory openings, and harness adapters can help preserve the original wiring connection. If your vehicle has the factory subwoofer, verify the system layout before adding or replacing bass equipment. Take care not to damage clips, vapor barriers, or wiring during removal. After installation, test each speaker location for balance, polarity, and proper operation before reinstalling all trim pieces.
Moderate difficulty, since door panel removal, fitment checks, and wiring verification are important.
Common Mistakes When Replacing Speakers
Here are the most common mistakes people make when shopping for audio upgrades for this 2009 Subaru Forester.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle. This model uses the same core speaker layout data, so the safer approach is to verify the front door and rear door locations on the specific vehicle before ordering parts.
- Assuming every trim has the same audio setup. Speaker count can range from 4 to 6, and amplifier details should be verified by trim and audio package because factory amplifier details are not universal across the lineup.
- Skipping a check for tweeters if equipped. The data shows front tweeters may be present, so confirm whether the vehicle has them before choosing replacement parts or planning a system upgrade.
- Ignoring mounting depth and connector style before buying speakers. Even when the size is listed as 6.5 inch, the physical fit still depends on depth clearance and the factory connector type, so those details should be checked first.
- Replacing parts without testing the system before reassembly. After installation, confirm every speaker location plays correctly and that balance, fade, and any factory audio features still work before putting the panels back together.
Generation & Model Family
The 2009 Subaru Forester belongs to the Third generation (SH) (2009–2010) 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 2009 Subaru Forester in the Third generation (SH) platform uses a simple speaker layout, but equipment can vary by trim and audio package. Some trims may include an optional amplifier, and tweeters are listed if equipped. That makes the best upgrade path depend on your current system, your budget, and whether you want cleaner sound, more output, or a factory-style result.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Start with the front stage by upgrading the front door speakers and the front tweeters if equipped, then match the rear speakers to keep the cabin balanced. | Front-stage upgrades usually deliver the biggest improvement in vocals, detail, and high-frequency response. Since tweeters are listed if equipped, improving the front speaker set first gives the cleanest path to better clarity. |
| More bass | Add an aftermarket subwoofer system to complement the factory speakers, and verify the current audio package before choosing the best signal and power connection method. | No factory subwoofer is listed, so adding a dedicated sub is the most effective way to increase low-end output. Factory amplifier details should be verified by trim and audio package before planning the install. |
| Louder sound | Upgrade the main speakers first, then add an amplifier that is properly matched to the system. Properly matched speakers and amplifier integration can improve volume and reduce distortion. | A stronger system needs both speaker capability and clean power. Verify factory amp or premium system integration before adding aftermarket amplifiers so the new gear works correctly with the existing audio setup. |
| Budget improvement | Replace the front door speakers first, since they handle the most important part of the listening experience, and use same-size replacement speakers with correct mounting brackets. | This approach gives the best sound improvement for the money. Focusing on the front doors first improves everyday listening without requiring a full system overhaul. |
| 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 cabin looking original while still improving sound quality. It also helps maintain a tidy installation and reduces the need for visible modifications. |
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.
