Crossover vs SUV – Audio Differences
Body style can affect how rear speakers, trim panels, and cargo-area audio options are arranged, but this model has no body-style-specific speaker data in the database. Factory audio equipment can vary by trim and package, so confirm the exact setup before choosing upgrades or replacement parts.
What Speakers Fit the 2012 Subaru Forester?
Aftermarket fitment should start with the factory speaker locations listed for this 2012 Subaru Forester, but diameter alone is not enough. The front and rear door openings are listed as 6.5 inch full-range speakers, and front tweeters are included if equipped. Before buying, verify mounting depth, bracket style, connector type, and whether the vehicle has a factory-amplified audio system, since equipment can vary by trim and audio package.
Usually Safe Upgrades
- If your vehicle uses the front door location, a 6.5 inch full-range replacement is the starting point.
- If your vehicle uses the rear door location, a 6.5 inch full-range replacement is the starting point.
- If your vehicle has front tweeters, 1 inch tweeter replacements may also be part of the upgrade path.
- If your vehicle is equipped with a factory subwoofer, confirm the enclosure and wiring before choosing upgrades.
Check Before Buying
- Confirm the exact trim and audio package, since speaker count and amplifier setup can vary.
- Measure mounting depth and check for any adapter ring or bracket requirements before ordering.
- Verify connector style so the new speakers can be wired correctly.
- Check whether your system includes front tweeters or other optional audio equipment.
- If the vehicle has a factory amplifier, make sure the replacement speakers are suitable for that setup.
Installation Notes
The 2012 Subaru Forester uses 6.5-inch full-range speakers in the front and rear doors, and some setups may also include 1-inch front tweeters if equipped. Speaker count varies by trim, so verify the exact audio package before ordering parts. Installation usually starts with careful panel removal at the doors, followed by checking the factory wiring and connector style before disconnecting anything. A harness adapter is often helpful for keeping the factory wiring intact, and mounting adapters may be needed to secure aftermarket speakers in the door openings. Speaker depth should be checked closely because clearance behind the door panel can be limited. If your vehicle has the factory subwoofer, confirm the system layout before planning upgrades. Take care when routing wires so they do not interfere with window tracks or trim clips. After installation, test each speaker location, balance, and fade setting before reassembling the panels fully.
Moderate difficulty, since trim removal, wiring checks, and fitment verification are important before installation.
Common Mistakes When Replacing Speakers
The 2012 Subaru Forester can vary a lot by trim and audio package, so these are the most common mistakes to avoid before ordering speakers or planning an upgrade.
- Buying based only on the body-style label instead of checking actual speaker locations on the vehicle.
- Skipping trim and audio package verification, even though speaker count can range from 4 to 7 and factory amplifier details should be confirmed by trim.
- Assuming every model has the same front speaker setup and ignoring the 1 inch tweeter location if equipped.
- Ordering speakers without checking mounting depth and connector style, which can cause fitment problems even when the size looks correct.
- Overlooking the rear door 6.5 inch full-range speakers and only planning around the front doors.
- Reassembling the doors before testing the new speakers and audio connections, which can make troubleshooting much harder if something is wired incorrectly.
Generation & Model Family
The 2012 Subaru Forester belongs to the Third generation (SH) - Facelift (2011–2013) 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 2012 Subaru Forester offers a straightforward upgrade starting point, with speaker equipment that can vary by trim and audio package. Front-stage upgrades are usually the best first step for most buyers, while higher trims may already include more speakers or factory audio options. Matching the upgrade to your trim helps you get better results without unnecessary parts.
| Goal | Best Upgrade Path | Why |
|---|---|---|
| Better clarity | Upgrade the front door speakers first, then add front tweeters if equipped to improve detail, vocals, and high-frequency response. | The front stage does most of the work for music clarity, and this model can include tweeters on some setups. Focusing on the front speakers and tweeters if equipped gives the cleanest improvement in mids and highs. |
| More bass | Add an aftermarket subwoofer to complement the factory speakers and verify how the factory audio system is configured before choosing the bass upgrade. | No factory subwoofer is listed in the vehicle data, so adding a sub is the most direct way to increase low-end output. Factory amplifier details should be verified by trim and audio package before planning the rest of the system. |
| 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 works best when the speakers and amplifier are matched correctly. Since factory amplifier details can vary by trim, checking the audio package first helps avoid integration issues and keeps the system balanced. |
| Budget improvement | Replace the front door speakers first with same-size replacement speakers with correct mounting brackets. | Front speakers are the most-used part of the system, so they usually deliver the biggest improvement for the money. Starting there keeps the upgrade focused and avoids spending on parts that have less impact. |
| 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. It also helps maintain the factory wiring layout and makes the upgrade easier to integrate with the existing audio system. |
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.
