Meet our premium 6.5” car audio 2-way coaxial RS65-CX. Focused on high-performance, these speakers were engineered and designed as the perfect solution for audiophiles looking to elevate their car audio system’s sound quality.
The RS Series brings new Subwoofers, amplifiers and car speakers with high-fidelity sound and performance for your everyday car system, specifically designed and developed for the car audio market.

- Small Profile – Designed for easier installation with its standard frame size that fits many OEM door speaker locations. 4 Ohm Impedance.
- 2-Way Coaxial – Built-in soft dome tweeter with in-line capacitor attenuates perfectly with the speaker, delivering rich, detailed sound.
- These 6.5″ coaxial speakers utilize a high quality silk dome tweeter and woofer, providing more accurate audio at 90dB sensitivity, superior to most stock car audio speakers.
- The RS65-CX 2-way coaxial does not require a large amount of power to operate. They get loud extremely easy with 160 watts RMS per pair making it suitable for use with the compact QS400.4 2 Ohm.

RS65-CX is designed for easy installation with a standard 6.5″ frame size that fits many OEM door speaker locations.
Although this coaxial was designed to be powered by an amplifier, it can also be used in a factory or aftermarket radio for good sound quality and better clarity over OEM speakers.
The RS65-CX will immerse you in the music no matter where you are in your vehicle. Upgrade today and hear the difference!

This 2-Way Car Coaxial speaker is an excellent upgrade for listeners wanting to go beyond the standard factory upgrade. With frequency responses ranging from 45Hz – 20,000Hz it delivers sound across the entire frequency spectrum.
Designed with a 6.5” woofer and a 1” Neodymium Tweeter with built-in crossover, the different components are each responsible for reproducing a specific frequency range, all connected from a single push-terminal, making for an easy installation without having to tune two separate components.
Built to perform and able to handle 80 Watts RMS each, these car speakers are the most ideal OEM replacement.
If your car has 4x 6.5″ speakers or just 2x 6.5″ + 2x 6×9” you will only need one amplifier to power these speakers to reach high output levels.
The compact QS400.4 2 Ohm amplifier is able to power all 4 speakers, one per channel, getting them extremely loud with a small amount of power.
