Skar Audio TX4 4" 2-Way Coaxial Car Speakers

The Skar Audio TX4 is a compact 4" two-way coaxial car speaker pair engineered to deliver clear mids, crisp highs and reliable power handling for factory or aftermarket installs.

These TX4 speakers combine a fiberglass cone, TPE surround and a 1.25" copper voice coil to offer a balanced audio upgrade where space is limited. Rated for 60W RMS per pair and 120W peak (per pair), they fit many door or dash locations and are built to withstand regular use. Below you’ll find concise answers to common buyer questions about performance, installation, and compatibility.

How will the TX4 improve my car’s sound quality?

The TX4 focuses on clearer midrange and detailed highs thanks to its fiberglass cone and dedicated tweeter design. You’ll notice more vocal presence and instrument separation versus most factory speakers without needing a large enclosure or amplifier.

• Fiberglass cone for controlled midrange response and reduced cone flex.
• 1.25" copper voice coil for stable power handling and thermal resilience.
• TPE surround to maintain cone linearity and reduce distortion at higher excursions.
• Two-way coaxial layout integrates a tweeter for improved high-frequency detail.

Can I install the TX4 in standard 4" openings and how difficult is installation?

Yes, the TX4 is sized for common 4" mounting locations found in many door and dash positions. Installation is straightforward for anyone familiar with car speaker swaps, using existing mounting points in most vehicles or simple adapters when needed.

• Fits typical 4" speaker cutouts in doors and dash panels.
• Uses standard wiring connections compatible with factory harnesses or inline adapters.
• Compact depth minimizes interference with window mechanisms and door hardware.
• Optional mounting adapters may be required for certain vehicle models.

What power sources and amplification do the TX4 speakers need?

The TX4 is rated to handle up to 120W peak (pair) with a RMS capacity of 60W per pair, making them a good match for stock head units or modest aftermarket amplifiers. For louder, cleaner output consider a small car amplifier for headroom and improved dynamic control.

• 60W RMS per pair supports consistent daily listening levels from many factory radios.
• Peak rating up to 120W per pair handles occasional high-volume transients.
• Works well with low-power OEM radios; a compact amp improves clarity and headroom.
• 1.25" copper voice coil tolerates heat for stable performance under higher power.

What materials and build features affect longevity and sound?

Materials like the fiberglass cone, TPE surround and copper voice coil were chosen to balance durability with sonic accuracy. These components help the speaker resist environmental stressors common in vehicles while keeping distortion low during normal playback.

• Fiberglass cone resists deformation and maintains consistent tonal balance.
• TPE surround offers long-lasting flexibility and reduces edge breakup.
• Copper voice coil improves thermal dissipation and power handling.
• Coaxial design reduces installation complexity while adding a high-frequency driver.

Who is this for: The Skar Audio TX4 4" 2-way coaxial speakers are aimed at drivers who need a compact, budget-friendly upgrade from factory speakers — especially in vehicles with limited mounting space. They suit owners seeking clearer vocals and better treble definition without large subwoofers or extensive amplifier installs. Choose the TX4 if you want an easy-to-fit solution that balances durability and improved everyday sound quality.
