Product Research
Features
Size Classification Note: The CLUB 644F comes mounted on a standard 4x6 bracket (the most common 4x6 application). While the brackets appear to be easily removable, they are glued in place at four points around the perimeter (in addition to the four screws, which are obvious). With the brackets in place, the speakers fit many top mount standard 4x6 and metric 4x6 applications. If the adapters are removed, the speakers will fit additional top mount metric 4x6 applications, as well as some bottom mount metric 4x6 applications.
Plus One Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One design offers greater bass output and an increase in efficiency.
High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.
The JBL Club 644F replaces these items:
- polypropylene Plus One woofer cone
- PEI balanced dome tweeter
- handles up to 40 watts RMS (120 watts peak power)

Easy to install. Requires some drilling on 2002 GMC Sierra but not too difficult. Make sure to purchase pigtail connectors to speed up install.
