STX Audio SX652 6.5" 2-Way Coaxial Car Speakers

The STX Audio SX652 is a pair of 6.5-inch 2-way coaxial car speakers designed to replace worn or basic factory speakers in common door and rear-deck locations. Each speaker combines a main cone and integrated high-frequency driver in one compact assembly. This makes the pair a practical option for vehicles that use standard-size full-range speaker positions.

With 160 watts RMS handling per pair and 650 watts maximum power per pair, the SX652 is intended for everyday listening with compatible factory radios or aftermarket audio systems. Its 4-ohm impedance is common in automotive speaker applications. The 90 dB sensitivity rating supports efficient operation with many head-unit-powered systems.

The 6.5-inch driver uses a black injection-molded cone and rubber edge surround to support controlled cone movement. This construction is intended to provide responsive midbass while covering a stated 68 Hz to 20 kHz frequency range. An integrated high-frequency driver completes the coaxial 2-way design for broad music playback from each mounting location.

STX Audio equips each SX652 speaker with a 1-inch aluminum voice coil, 15-ounce magnet, and black steel basket. These components form the speaker's motor and support structure for regular automotive use. The specified resonant frequency is 85 Hz.

The SX652 pair can be used as a direct-style upgrade where a vehicle accepts 6.5-inch speakers, subject to confirming physical fitment. They are suitable for front doors, rear doors, and rear-deck installations where mounting clearance and wiring are appropriate. The package includes two speakers and two matching gold-accent grilles for custom installations or replacement applications.

Key Features

• 6.5-Inch Coaxial Pair: Combines midrange and high-frequency reproduction in compact speaker assemblies.
• 160W RMS Per Pair: Provides 80 watts RMS handling per speaker.
• 4-Ohm Impedance: Works with many factory and aftermarket car audio systems.
• Rubber Edge Surround: Supports controlled cone travel and midbass response.
• Aluminum Voice Coil: Uses a 1-inch coil for thermal handling support.
• Included Grilles: Two matching gold-accent grilles accompany the speaker pair.

Design & Installation

Each SX652 uses a black injection-molded cone, rubber edge surround, black steel basket, 1-inch aluminum voice coil, and 15-ounce magnet. The integrated high-frequency driver is positioned within the coaxial speaker assembly, helping keep the installation footprint suited to conventional 6.5-inch speaker locations. The supplied grilles offer an additional finishing option for exposed custom installations.

Before installation, verify the vehicle's speaker cutout, mounting depth, mounting-hole pattern, and terminal or connector requirements. The speakers use conventional wired connections and may require vehicle-specific adapters, mounting brackets, or wiring harnesses depending on the application. Match the amplifier or head unit to the speakers' 4-ohm load and avoid exceeding their stated power-handling ratings.
