CT Sounds 4x6 Coaxial Car Speakers — 160W Peak Pair

Designed for drivers who want a clear, full sound upgrade without changing speaker locations, these 4x6-inch coaxial speakers combine a polypropylene woofer and a silk-dome tweeter in one compact assembly. They work with factory radios, aftermarket head units, or multichannel amplifiers, and ship with grille covers, pre-wired connectors, mounting hardware, and a wiring manual to make installation straightforward.

What sound improvements can I expect from the BIO-4X6-COX?

These speakers aim to tighten low end and bring clearer mids and highs compared with typical factory speakers. The silk-dome tweeter improves high-frequency detail while the polypropylene woofer provides consistent mid-bass response for music and podcasts.

• Two-way coaxial design for integrated highs and mids
• Silk-dome tweeter for smoother treble and vocal clarity
• Polypropylene woofer for stable midrange and controlled bass
• Balanced tonal profile without needing external crossovers

How much power do these speakers handle and what will they work with?

Each speaker is rated at 40 watts RMS (80 watts max), giving a combined system rating of 80 watts RMS and 160 watts peak. That power range makes them safe to run from a factory head unit, improves with an aftermarket deck, and scales further when driven by a multichannel amp.

• Impedance: 4 ohms per speaker for broad compatibility
• 40 W RMS per speaker for reliable continuous output
• 80 W max per speaker for short-term peaks
• Works with factory or aftermarket head units and amps

What comes in the box and how difficult is installation?

The pair ships with everything you need to swap out factory speakers: grilles, premium speaker wire with pre-crimped female spade connectors, screws, mounting clips, and a manual that includes wiring diagrams. If you can follow basic wiring and mounting steps, installation is direct; adapters or trimming may be needed for some vehicle-specific openings.

• Includes two CT Sounds 4x6" speaker grilles for protection and style
• Two premium wires with pre-crimped spade connectors for easy hookup
• Eight mounting screws and eight clips to secure both speakers
• Product manual with wiring diagrams to simplify installation

Will these speakers fit my car and how do they mount?

The 4x6" form factor is a common replacement size in many cars and trucks but confirm your vehicle's speaker opening before buying. Mounting uses the supplied screws and clips; some cars may require OEM adapter plates or slight trimming to fit exactly.

• Standard 4x6" footprint fits many factory locations
• Mounts with supplied 1" screws and mounting clips for stability
• Adapters may be needed for nonstandard mounting patterns
• Wiring harness compatibility improved by included pre-crimped wires

Who is this for: The CT Sounds BIO-4X6-COX pair is aimed at drivers who want a straightforward, budget-friendly audio upgrade from stock speakers without modifying speaker locations. It suits owners of vehicles with 4x6" openings who want fuller sound, easier installation, and compatibility with factory or aftermarket electronics.
