Comparison with Aftermarket Options
The GS1E665 960 offers distinct advantages and some trade-offs when compared to aftermarket speakers. Understanding these differences helps you make an informed decision.
OEM Advantages
Factory speakers guarantee a perfect fit without modifications. The design ensures perfect alignment with Mazda’s factory specifications, eliminating the need for complex adjustments. Price points remain more affordable than many aftermarket alternatives.
Electrical compatibility with factory head units is guaranteed. You avoid potential impedance mismatches that can damage amplifiers. Warranty coverage through authorized dealers provides additional peace of mind.
Aftermarket Considerations
Aftermarket 6×8 speakers often feature frequency ranges from 50 Hz to 20 kHz with higher sensitivity ratings exceeding 90 dB. These specs translate to louder output and deeper bass response.
Premium aftermarket options use advanced materials. Polypropylene woofers provide durability and good bass response, while silk or metal dome tweeters offer smooth or bright highs, respectively. Build quality improvements can extend speaker lifespan.
Power handling capacity typically exceeds OEM specifications. Many aftermarket 6×8 speakers handle 50-100 watts RMS, allowing pairing with external amplifiers for increased output.
| Feature | GS1E665 960 OEM | Aftermarket Average |
|---|---|---|
| Power (RMS) | 25 watts | 50-100 watts |
| Sensitivity | 88-91 dB | 90-94 dB |
| Frequency Range | 80-18,000 Hz | 50-20,000 Hz |
| Installation | Direct fit | May require adapters |
| Price Range | $30-50 | $50-150 |
- OEM speakers prioritize fit and compatibility
- Aftermarket options offer higher performance potential
- Budget and audio goals determine the best choice
Maintenance and Troubleshooting
It’s time to replace your GS1E665 960 speaker if you hear distorted or muffled audio, see visible damage like tears or cracks, or experience inconsistent audio output.
Regular maintenance extends speaker life. Clean speaker grilles periodically to prevent dust accumulation that can affect sound quality. Inspect mounting screws annually to ensure they remain tight, as vibrations can loosen connections over time.
Avoid water exposure when cleaning door panels. Moisture damage affects cone material and voice coil performance. If speakers get wet, allow complete drying before powering the system.
Common issues include rattling sounds from loose mounting, which requires tightening screws. Audio cutting in and out typically indicates wiring harness problems at connections. Test connections and clean contact points if oxidation appears.
Distortion at high volumes often means the speaker has reached its power handling limit. Reduce volume or consider upgrading to higher-wattage aftermarket speakers if you frequently listen at maximum levels.
- Replace speakers showing physical damage or distortion
- Keep mounting hardware tight to prevent rattles
- Protect speakers from moisture exposure
