【KSC6904 6×9-inch Speakers｜Enjoy Clear Sound Even with OEM Audio】

Do you want a little more body in the sound of your factory speakers, or want to hear vocals and instrument sounds more clearly? If so, we recommend the KSC6904.

Featuring a 6×9-inch large-diameter cone, it delivers a powerful low end with depth and extendability. Even when you want to enjoy music at a slightly higher volume, it won’t be the bass alone that stands out—together with the clear high frequencies from the aluminum dome tweeter, this speaker reproduces the entire sound spectrum solidly.

System upgrades using an external amplifier are, of course, supported. What’s more, its high-efficiency design makes it easy to drive even with the built-in amplifier of OEM audio. It’s ideal for those who don’t plan on making major system changes but still want to improve sound by replacing the speakers first.

Three types of mounting brackets are included for the tweeters, so you can consider the best installation method depending on your vehicle model and setup. However, whether the 6×9-inch size fits as-is, and what parts or fabrication are required for installation, will vary by vehicle.

Even with the same speaker, the overall sound cohesion can change depending on factors such as the door-side base and mounting method, wiring treatment, and post-installation adjustments. At LOGON, we work with you to find an installation approach that maximizes the strengths of the KSC6904—by confirming not only your vehicle model, but also the configuration of your OEM audio, the music you typically listen to, and your preferred listening volume.
