BLAUPUNKT GTX650 6.5" 4-Way Coaxial Car Speakers 120W RMS

The BLAUPUNKT GTX650 6.5-inch 4-way coaxial speakers are a pair of car audio drivers built for clear highs, solid mids, and punchy bass at up to 360W peak power.

Designed by a brand with over nine decades of audio engineering, these 6.5" coaxial speakers bring a complete four-way setup in a single, easy-to-install unit. They combine a polypropylene woofer cone, butyl rubber surround, Mylar dome tweeter and a ceramic magnet to produce balanced sound across frequencies. With 120W RMS (360W peak) power handling and a sturdy high-temperature aluminum voice coil, the GTX650s are aimed at drivers who want reliable, upgraded in-car sound without complex component crossovers.

What sound improvements will I notice right away?

Expect clearer treble and fuller bass compared with many stock speakers. The Mylar dome tweeter sharpens high frequencies while the polypropylene cone keeps midrange vocals natural. The butyl rubber surround increases excursion for tighter low-end response without muddiness.

• Defined highs from Mylar dome tweeter
• Natural mids via polypropylene woofer cone
• Tighter bass with butyl rubber surround and robust motor structure
• Reduced distortion at moderate volumes thanks to a 1" aluminum voice coil

How easy is installation in standard cars?

The GTX650 set is intended as a drop-in or near-drop-in 6.5" replacement for many factory locations. Their coaxial design eliminates the need for separate component speakers and simplifies wiring. You'll still want to check mounting depth and frame diameter for a seamless fit.

• Fits common 6.5" factory speaker locations
• Coaxial build removes need for external crossovers
• Sturdy ceramic magnet and frame for stable mounting
• Compatible with head units and most aftermarket amps at 120W RMS

Which specs matter for power and reliability?

The GTX650s are rated 120W RMS and 360W peak power, so pair them with a head unit or amp that matches the continuous (RMS) rating for consistent performance. The high-temperature 1" aluminum voice coil improves thermal handling, and the ceramic magnet provides a durable motor assembly for long-term reliability.

• 120W RMS / 360W peak handling
• 1" high-temperature aluminum voice coil for heat resistance
• Ceramic magnet for stable magnetic flux
• Polypropylene cone for weather-tolerant performance

Will these speakers work with an external amplifier?

Yes—an external amp can improve dynamics and headroom when matched to the speakers’ RMS rating. Use an amplifier that delivers clear power near 120W RMS per speaker for optimal balance and avoid overpowering peaks that exceed the 360W peak rating.

• Recommended amp: RMS output close to 120W per channel
• Use proper gain setting to minimize clipping
• Capable of use with factory radios at moderate volume levels
• Coaxial design stays compatible with simpler systems

Who is this for: The BLAUPUNKT GTX650 pair suits drivers who want a straightforward upgrade from factory speakers to a fuller, more detailed sound without installing separate component systems. They’re a good fit for those seeking reliable build quality, moderate power capability, and an uncomplicated installation in most 6.5" car speaker locations.
