SQ stands for sound quality
It's time to make your factory sound a fading memory. JBL prioritizes sound quality with this specialty Club Series 605CSQ 6-1/2" component speaker system for a uniquely immersive experience in the car. The carbon fiber woofer with its powerful ferrite magnet delivers the lower frequencies with refreshing accuracy while the separate edge-driven silk dome tweeter ensures you'll hear all the natural detail of your favorite tunes. Adjust your tweeter volume to dial in the right sound for your vehicle.
Installation gear for your tweeters
Jump into your installation with the right mounting accessories for a clean look. JBL's I-Mount™ kit and Starfish™ mounting adapter give you flexibility to flush-mount and more.
A match for any system
The Club 605CSQ's low-impedance/high-sensitivity design safely draws more power from your car stereo to give your music extra punch, but you'll get even better results feeding them power from an outboard amp.

Frequently Asked Questions (FAQ)
Q: What is the main difference between the JBL Club 602C and the JBL Club 605CSQ?
A: While both are 6.5" 2-way component sets, the Club 605CSQ is the upgraded "Sound Quality" (SQ) model. The 605CSQ upgrades from a standard polypropylene cone to a stiffer carbon fiber cone, uses a stronger Y40 ferrite magnet, handles slightly higher RMS power (95W RMS vs. 70W RMS), and digs lower in bass response (48 Hz vs 55 Hz).
Q: What does the tweeter adjustment switch on the crossover do?
A: The crossover features a 0dB / +3dB toggle switch. If your tweeters are mounted low in the door or behind thick factory grilles, setting it to +3dB boosts high frequencies so they cut through clean. If the tweeters are mounted high on your A-pillars pointing right at your ears, leaving it at 0dB gives you a neutral, balanced tone.
Q: Will these speakers run fine off a standard factory radio?
A: Yes! Thanks to JBL’s high 93 dB sensitivity rating and low 3-ohm impedance, the 605CSQ will play efficiently on factory radio power. However, because of the carbon fiber woofer's capability, pairing them with an external amplifier (50W to 100W RMS per channel) will significantly improve dynamic range and bass performance.
