Its coaxial format combines multiple speaker elements into a single mounting location, helping retain a straightforward door- or panel-speaker upgrade path. The system is rated at 4 ohms per speaker for use in common automotive audio applications.\u003c\/p\u003e\u003cp\u003eThis speaker set is intended for drivers who want to refresh aging factory speakers or build a basic full-range system without adding separate component speaker locations. It can be operated from a factory head unit or paired with a multichannel amplifier. With 90 watts RMS rated per speaker, it offers a practical power-handling match for moderate aftermarket amplification.\u003c\/p\u003e\u003cp\u003eThe STX-654 uses a 4-way full-range design to cover a broad listening range from a compact 6.5-inch format. Its listed 60 Hz to 20 kHz frequency response is suited to reproducing much of the vocal, instrument, and high-frequency content in a vehicle audio system. Dedicated subwoofers may still be useful in systems that need stronger low-bass output.\u003c\/p\u003e\u003cp\u003eA silk-dome tweeter is integrated with the woofer assembly, while the woofer is listed with a polypropylene construction. This integrated arrangement keeps the high-frequency driver aligned with the main speaker location and avoids the need to mount a separate tweeter. A moisture-resistant rubber surround is also specified for the speaker design.\u003c\/p\u003e\u003cp\u003eFor installation, the STX-654 is built around an anti-resonant stamped-steel basket and uses spade speaker terminals. Its listed 2-7\/8-inch mounting depth should be checked against available clearance behind the intended mounting panel. It can serve as a direct-size replacement where a vehicle accepts 6.5-inch speakers, subject to verifying vehicle-specific cutout, mounting-hole, and depth requirements.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.5-Inch Coaxial Format:\u003c\/strong\u003e Fits applications designed for compatible 6.5-inch car speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Way Full-Range Design:\u003c\/strong\u003e Combines multiple speaker elements in one assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90W RMS Per Speaker:\u003c\/strong\u003e Supports moderate continuous amplifier power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Matches common automotive speaker wiring configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilk-Dome Tweeter:\u003c\/strong\u003e Adds dedicated high-frequency reproduction within the speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStamped-Steel Basket:\u003c\/strong\u003e Provides a rigid mounting structure for installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STX-654 combines a polypropylene woofer and silk-dome tweeter in a single coaxial assembly.
