Tech Complex Technical Team Opinion

Conclusion: The GX628 is a reliable choice for upgrading front/rear doors in the 6.5" size, delivering clear, balanced sound and realistic high detail.

• Works on the head unit thanks to its high sensitivity and 2.3Ω impedance; we recommend an external amplifier for those who want a stronger boost and better control at high volume levels.
• Improve the result with professional installation and light door lining to reduce resonance and enhance bass quality.
