Skar Audio 6.5" Coaxial Car Speakers RPX65 – 2-Way Pair

Swap out worn factory drivers with the RPX65 pair to instantly improve in-car clarity and detail without needing a new head unit or external amp. These 6.5-inch coaxials combine a microfiber paper mid-woofer with a 20mm aluminum dome tweeter and durable butyl rubber surround to balance musicality and durability. With a 40–20,000 Hz frequency range and 89 dB sensitivity, they work well on stock radio output and respond cleanly to aftermarket amplification.

How do these speakers fit existing factory locations?

The RPX65 speakers use a common 6.5" mounting footprint and standard depth, making them compatible with most OEM locations in cars and trucks. Their coaxial design keeps installation simple because the tweeter is integrated with the woofer, so you do not need extra crossovers or tweeter mounts.

• Standard 6.5" diameter for direct replacement in many vehicles
• Integrated tweeter simplifies wiring and mounting
• Shallow magnet and basket profile for tight factory speaker wells

What kind of sound improvement should I expect?

Expect tighter low-mid response and crisper highs compared with typical factory paper cones. The microfiber paper cone and butyl surround reduce unwanted resonance, while the aluminum dome tweeter adds air and detail to vocals and cymbals. Overall, the RPX65s produce a fuller, more balanced soundstage whether driven by a stock head unit or a modest amplifier.

• 40–20,000 Hz range captures deep mid-bass through clear treble
• 20mm aluminum dome tweeter for improved high-frequency detail
• 89 dB sensitivity helps them play louder with factory radio power

How much power can they handle and what amp works best?

The pair is rated to 200 watts peak and 60 watts RMS overall, with a 4-ohm impedance, so they’re comfortable on stock head units and benefit from a small external amp. If you want more dynamic headroom and lower distortion at higher volumes, a compact 50–75W RMS per channel amplifier will let the speakers perform closer to their potential.

• Pair RMS: 60 watts; Pair peak: 200 watts
• Nominal impedance: 4 ohms for compatibility with most car systems
• Ideal amp range: 50–75W RMS per channel for cleaner playback

What materials and design features improve durability?

These speakers pair a microfiber paper cone with a premium butyl rubber surround to withstand temperature swings and road vibration while retaining musical accuracy. The aluminum dome tweeter resists fatigue and keeps high frequencies consistent over time, and overall build quality targets long-term reliability for daily driving conditions.

• Microfiber paper cone for natural midrange and controlled breakup
• Butyl rubber surround resists heat and age better than foam
• Aluminum dome tweeter designed for stable high-frequency response

Who is this for? The Skar Audio RPX65 pair is aimed at drivers who want a noticeable sonic upgrade from worn or basic factory speakers without complicated installation or major system changes. They suit commuters, weekend road-trippers, and budget-conscious audiophiles wanting better clarity, improved highs, and reliable construction in a direct-fit 6.5" package.
