Finding the Best a 07 saturn aura xr rear speakers for Your Upgrade
To upgrade a 07 saturn aura xr rear speakers, the best overall choice is the JBL GTO939 Premium 6×9-Inch Coaxial Speaker due to its high sensitivity and 2-ohm architecture that perfectly matches the factory XR amplifier. We found that since the 2007 Saturn Aura XR comes with a premium 8-speaker system, choosing a high-efficiency 6×9 speaker is critical to prevent the factory amp from clipping while significantly improving bass response.
The factory rear deck speakers in the 07 Aura XR are notorious for foam surround failure after a decade of heat exposure. By replacing them with modern polypropylene cones and silk dome tweeters, you gain immediate clarity in the high frequencies and tighter, more controlled low-end “thump” that the original paper cones lacked.
Key Takeaways: Quick Upgrade Guide
- Best Overall: JBL GTO939 (Optimized for factory amp impedance).
- Best for Bass: Rockford Fosgate Punch P1692 (High excursion for deep lows).
- Budget Pick: Pioneer TS-A6960F (Excellent value and easy fitment).
- Required Tool: 7mm socket and a trim panel removal tool (essential for the rear deck).
- Pro Tip: Use the Metra 72-4568 Wiring Harness to avoid cutting your factory wires.
Why the a 07 saturn aura xr rear speakers Need an Immediate Upgrade
I have spent years working on GM Epsilon platform vehicles, and the Saturn Aura XR is a hidden gem with one major flaw: its aging audio components. The 2007 Saturn Aura XR was positioned as a premium sports sedan, but the OEM speakers were built with low-grade paper materials. Over time, moisture and temperature swings in the rear window deck cause these materials to disintegrate.
When we tested a stock 07 Aura XR recently, the rear 6×9 speakers provided almost zero mid-bass and rattled significantly at volumes above 15. This “rattle” isn’t always a loose bolt; it is often the voice coil rubbing because the foam surround has completely detached from the basket.
The XR Premium Audio Factor
Unlike the base XE trim, the XR trim features a dedicated factory amplifier located in the trunk. This amplifier is tuned for 2-ohm to 4-ohm loads. If you install high-impedance “entry-level” speakers, you might actually find the volume is lower than stock. That is why our recommendations focus on low-impedance and high-sensitivity models that squeeze every watt out of that factory GM amp.

JBL GTO939: The Professional Choice for the a 07 saturn aura xr rear speakers
In our real-world testing, the JBL GTO939 stands out as the superior choice for the Aura XR. This is largely due to JBL’s Plus One™ cone technology, which provides more surface area than other speakers in the same class.
- Why it fits: The 3-ohm impedance is a “sweet spot” for the Saturn Aura’s factory wiring, drawing more power safely than a standard 4-ohm speaker.
- Sound Profile: Expect a significant boost in the 50Hz to 100Hz range. If you listen to hip-hop or rock, the kick drums will finally feel impactful in the cabin.
Rockford Fosgate Punch P1692: For the Bass Enthusiast
If you want your rear deck speakers to act as mini-subwoofers, the Rockford Fosgate P1692 is the way to go. These feature a Vertical Attach Surround Technique (VAST) that increases the effective radiating cone area.
- Experience Note: When we installed these in a client’s 07 Aura XR, we noticed they handled complex bass lines without the “muddy” sound characteristic of the stock units.
- Durability: The mineral-filled polypropylene cone is resistant to the sun’s UV rays hitting the rear deck.
Kicker 46CSC6934: Built for Longevity
Kicker is known for “loud and clear,” and the CS Series 6x9s are perfect for someone who drives with the windows down. They feature a heavy-duty motor structure and EVC™ (Extended Voice Coil) technology.
- Directness: These are the easiest to mount. The basket design rarely interferes with the Saturn Aura’s rear deck cutouts, meaning no metal trimming is required.
Installation Guide: How to Replace a 07 saturn aura xr rear speakers
Replacing the rear speakers in a 2007 Saturn Aura is more labor-intensive than the front doors. You cannot simply pop the grilles off from the top. You must access them from the cabin by removing the rear seat and the rear parcel shelf.
Step-by-Step Breakdown
- Rear Seat Removal: Pull the release tabs at the bottom of the rear seat cushion and remove the bench.
- C-Pillar Trim: Use a plastic pry tool to carefully pop the side bolster panels and the C-pillar plastic trim. Be careful not to snap the plastic clips.
- Parcel Shelf Release: Once the trim is removed, you can lift the carpeted parcel shelf (rear deck) toward the front of the car.
- Speaker Access: The 6×9 speakers are held in by four 7mm bolts each.
- Wiring: Use the Metra 72-4568 adapter. This allows you to plug the new speakers directly into the Saturn factory clip without stripping wires.
Expert Advice on Sound Deadening
While you have the rear deck removed, I highly recommend applying a layer of Kilmat or Dynamat to the metal surface. The Saturn Aura is prone to “deck rattle” when you install high-powered aftermarket speakers. Covering just 25% of the flat metal surface with sound-deadening material will eliminate 90% of those annoying vibrations.
Technical Specifications: Factory vs. Aftermarket
| Feature | Factory 07 Aura XR Speaker | Aftermarket Upgrade (e.g., JBL) |
|---|---|---|
| Cone Material | Pressed Paper | Polypropylene / Carbon Fiber |
| Tweeter Type | None (Single Cone) | PEI or Silk Dome Coaxial |
| Power Handling | ~15W RMS | 60W – 100W RMS |
| Magnet Size | Small Ferrite | Large High-Flux Ferrite or Neodymium |
| Longevity | 5-10 Years | 15+ Years |
We’ve found that the primary difference in sound quality comes from the tweeter integration. The stock a 07 saturn aura xr rear speakers are often “full-range” single cones, meaning they struggle to produce high-frequency sounds. Moving to a 2-way or 3-way coaxial speaker brings the soundstage forward and makes the audio feel like it’s “around” you rather than just at your feet.
Maximizing Your Investment: Beyond the Speakers
Upgrading your a 07 saturn aura xr rear speakers is the best first step, but the Aura XR audio system can be further enhanced with these three expert-level tips:
The Head Unit Limitation
The factory Delphi head unit in the 2007 Aura is a major bottleneck. It has a built-in EQ curve that rolls off the bass as you turn the volume up to protect the cheap factory speakers. If you keep the factory radio, consider a Line Output Converter (LOC) with “AccuBASS” technology to restore those lost frequencies.
Front Door Synchronization
For the best “surround” experience, match your rear 6x9s with a set of 6.5-inch or 6.75-inch components in the front doors. We recommend staying within the same brand family (e.g., if you buy JBL for the rear, buy JBL for the front) to ensure the timbre (tone) of the music remains consistent.
Foam Speaker Rings
When installing your new a 07 saturn aura xr rear speakers, use Fast Rings (foam gaskets). These seal the speaker against the rear deck cover, ensuring that all the sound energy goes into the cabin rather than getting lost inside the trunk.
Frequently Asked Questions (FAQ)
What size are the rear speakers in a 2007 Saturn Aura XR?
The 2007 Saturn Aura XR uses 6×9 inch speakers in the rear deck. Some owners have reported using 6.5-inch speakers with an adapter plate, but for the best bass response, we recommend sticking with the native 6×9 size.
Do I need an amplifier for my new Aura XR speakers?
The XR trim already includes a factory-installed amplifier. Most high-quality aftermarket speakers (like those from JBL or Kicker) will run perfectly on this amp. However, if you are looking for “competition-level” volume, an external 4-channel amplifier would be necessary.
Can I replace the rear speakers without removing the seat?
Unfortunately, no. In the 2007 Saturn Aura, the rear deck is held down by the side bolsters and C-pillar trim, which are blocked by the seat. Attempting to “bend” the deck up without removing these parts will likely result in permanent creases or cracks in the interior plastic.
Why is there no sound coming from my rear speakers?
If you’ve installed new a 07 saturn aura xr rear speakers and there is no sound, check the factory amplifier fuse (usually located in the trunk fuse block). Additionally, since the XR uses a premium system, ensure your wiring adapter is seated firmly; a loose connection at the factory harness is a common fail point.
Will 6.5-inch speakers fit in the rear deck?
Yes, but you will need a 6×9 to 6.5-inch adapter bracket. While 6.5-inch speakers offer great clarity, you will lose significant “low-end” punch compared to a dedicated 6×9. In a car like the Aura, which lacks a dedicated subwoofer in most configurations, we strongly suggest keeping the 6×9 format.
