CSC674 Rear sliding door coaxial 2-way

Even to the back seats, your usual music spreads comfortably.

【CSC674 16.5cm 2-Way Coaxial Speakers for Rear Sliding Doors】

These 16.5cm 2-Way coaxial speakers are designed for those who want to replace the factory speakers in the rear sliding doors and make music a bit easier to listen to from the back seat.

CS series speakers that are easy to use as an upgrade from the factory speakers. With a thin, steel frame and a zero-tweeter structure that helps minimize interference with the door lining, they are designed to make it easier to consider a direct replacement in rear sliding doors.

They are ideal for people who often listen to music from the back seat, or for those who want to tune the sound throughout the entire cabin—not just in the front. However, the speaker mounting space and the specifications of the factory speakers vary by vehicle model, so even the same 16.5cm size may not be a direct swap. It’s important to confirm the mounting hole, depth, interference with the door lining, and other factors, then choose the method that fits your vehicle.

At LOGON, we don’t just stop at installing the speakers—we guide you while considering compatibility with the factory system, the volume balance between front and rear, and even the condition on the door side. Depending on whether you want to add rear sound naturally or enjoy music properly even in the back seat, the suitable combinations and installation methods will change. Let’s review your vehicle model and how you use it, and think together about a configuration that won’t be a burden.
