The STX Audio SX652 is a pair of 6.5-inch, 2-way coaxial car speakers designed to replace compatible factory door or rear-deck speakers. They provide a compact full-range solution for vehicles needing refreshed sound without changing the basic speaker-location layout. Their 4-ohm design is suited to many factory-radio and aftermarket car-audio applications.
Each speaker combines a black injection-molded cone with an integrated high-frequency driver. This coaxial layout places the drivers in one assembly, helping deliver music across the stated 68 Hz to 20 kHz frequency range while keeping installation straightforward. The result is intended for everyday listening in common 6.5-inch speaker positions.
The SX652 pair is rated for 160 watts RMS total, equal to 80 watts RMS per speaker, and 650 watts maximum power. With 90 dB sensitivity, the speakers are specified for efficient operation with compatible source units or amplification. Match the amplifier's output and crossover settings to the speakers' RMS rating for responsible system setup.
A rubber edge surround supports controlled cone movement for midbass reproduction, while the 1-inch aluminum voice coil and 15-ounce magnet form the speaker motor assembly. The black steel basket provides a stable mounting structure. These materials make the SX652 a practical choice for replacing worn factory speakers or building a simple speaker upgrade.
The package includes two SX652 coaxial speakers and two matching gold-accent grilles. Use them as a pair in front doors, rear doors, or rear-deck locations where fitment permits. Before ordering, confirm the vehicle's speaker opening, mounting depth, mounting-hole arrangement, and wiring connection requirements.
Key Features
- 6.5-Inch Coaxial Pair: Two speakers provide a matched replacement set for compatible vehicle locations.
- 2-Way Driver Layout: An integrated high-frequency driver supports full-range music playback from one assembly.
- 80W RMS Per Speaker: Supports power matching with compatible factory or aftermarket amplification.
- 4-Ohm Impedance: Works with many conventional car-audio speaker outputs.
- Rubber Edge Surround: Helps support controlled cone movement during daily listening.
- Included Gold-Accent Grilles: Adds protective finishing hardware for suitable custom installations.
Design & Installation
The SX652 uses a black injection-molded cone, rubber edge surround, 1-inch aluminum voice coil, 15-ounce magnet, and black steel basket. Its coaxial construction integrates the high-frequency driver into the 6.5-inch speaker assembly. The included grilles have gold accents for a finished appearance where the factory panel does not cover the speakers.
Check the vehicle's cutout diameter, available mounting depth, screw pattern, and terminal or adapter needs before installation, as exact vehicle fitment varies. Disconnect vehicle power as appropriate before wiring and observe speaker polarity at both channels. The speakers can be used for compatible front-door, rear-door, or rear-deck replacements and should be paired with amplification appropriate for 80 watts RMS per speaker.

Will these fit my vehicle's factory 6.5-inch speaker location?
They are designed for common 6.5-inch door and rear-deck locations, but vehicle fitment is not universal. Confirm the cutout diameter, mounting depth, mounting-hole pattern, and connector requirements before purchase.
How much power can each SX652 speaker handle?
The pair is rated at 160 watts RMS total, or 80 watts RMS per speaker. The stated maximum-power rating is 650 watts for the pair.
Can I use these with a factory radio?
Their 4-ohm impedance and 90 dB sensitivity make them suited to many factory-radio upgrades. Actual output depends on the radio, vehicle wiring, and installation.
Do I need separate tweeters or external crossovers?
No separate tweeters are required for the basic speaker setup because each SX652 is a 2-way coaxial speaker with an integrated high-frequency driver. External crossover specifications are not confirmed.
What is included in the package?
The package includes two STX Audio SX652 coaxial speakers and two matching gold-accent grilles. Mounting hardware, wire adapters, and vehicle-specific brackets are not confirmed.
What amplifier output is appropriate?
For amplified use, select compatible 4-ohm channels and match output responsibly to the 80-watt RMS rating per speaker. Avoid relying on maximum-power ratings when matching amplifier power.
