Tech Complex Technical Team Opinion
Conclusion: The Stage3 6427 is well suited for enhancing clarity in 4x6 in-dash/door locations, works efficiently on the head unit, and does not require an amplifier for everyday use.
- We recommend focusing on the front for the soundstage, while using the rear as a light rear fill to fill the cabin.
- Professional fit with light padding enhances bass quality and reduces resonance.
