Skar Audio 4x6 Coaxial Car Speakers RPX46

The Skar Audio RPX46 are 4"x6" two-way coaxial car speakers that deliver clear, full-range sound with a silk dome tweeter and durable microfiber paper cone for reliable everyday listening.

These RPX46 speakers are designed as direct factory replacements or upgrades for vehicles that use 4x6 speakers. Built with a microfiber paper cone, a premium butyl rubber surround and a 20mm soft silk dome tweeter, they balance low-mid detail with smooth high frequencies while tolerating both head-unit and amplified power. Rated at 4 ohms with a 91 dB sensitivity, they reproduce a wide frequency range and are sold as a matched pair ready for installation.

How will the RPX46 affect my car's soundstage and clarity?

The two-way coaxial layout separates highs and mids so vocals and instruments stand out with less distortion at moderate volume. The silk dome tweeter smooths high frequencies to reduce harshness, while the microfiber cone maintains midrange accuracy for a balanced soundstage.

• 20mm soft dome silk tweeter for refined high-frequency detail
• Microfiber paper cone for tight midrange response
• 91 dB sensitivity helps deliver loudness from factory radios

Can these speakers handle factory radio power or aftermarket amps?

Yes — the RPX46 perform well with both stock radios and external amplifiers. They tolerate peak power up to 150 watts per pair and continuous (RMS) power of 45 watts per pair, making them versatile for different power setups.

• Impedance: 4 ohms for broad compatibility
• Peak power handling: 150 watts per pair (75 watts each)
• RMS power: 45 watts per pair for steady listening levels

What durability features help these speakers last in a car environment?

Materials and construction focus on vibration resistance and longevity. The butyl rubber surround resists environmental degradation and provides long excursion life, while the stiff yet lightweight microfiber cone resists breakup for consistent performance.

• Premium butyl rubber surround for weather and heat resilience
• Microfiber paper cone resists deformation and maintains tonal balance
• Coaxial tweeter integration reduces added hardware and failure points

Which frequencies do the RPX46 cover, and how loud will they get?

The speakers deliver a broad frequency range that covers most musical content, from deep lows to extended highs. With a sensitivity near 91 dB, they efficiently convert power into audible volume, making them suitable for clear playback without excessive amplification.

• Frequency response: 40–25,000 Hz ±3 dB for wide coverage
• Sensitivity: 91 dB for efficient output from head units
• Tuned for balanced bass and crisp treble in small speaker footprints

Who is this for? The Skar Audio RPX46 are ideal for drivers seeking a reliable, full-range upgrade for factory speaker locations or for anyone replacing worn 4x6 speakers without changing head units. They suit daily commuters, weekend drivers, and audio-minded owners who want improved clarity and durability from a compact coaxial speaker pair. Sold as a pair, they make swapping factory components straightforward while offering materials and frequency performance that elevate in-car listening.
