Tech Complex Technical Team Opinion

Conclusion: The JBL GTO609C delivers clear, focused sound with precise vocal centering, primarily geared toward enhancing the soundscape.

• Requires the presence or installation of an amplifier for proper performance; operating on the head unit alone weakens the torque and detail.
• For a more full cabin feel, keep the rear fill light while keeping the front preponderant.
• Fits most cars with 6.5" door size.
• Suitable amplifier suggestion: JBL Stage A6004 or JBL Stadium 4 to feed the component with two clean channels.
• Professional installation with light door lining improves bass and reduces resonance.
