Installed these in my C-Class and the soundstage opened up immediately—the 60w RMS handling gives vocals much more clarity than the stock paper cones ever could. Bass response is tighter too, even without a sub.

The factory speakers always felt flat, but these 4-inch coaxials bring the mids to life without any cutting or wiring headaches. They’re a true OEM swap, and the 60w RMS handling means I can push them harder than the stock units without distortion.

Dropped these into the doors expecting a hassle, but the 4-inch size bolted right in with zero cutting. The 60w RMS rating is honest—clean vocals and decent bass at highway volume without distortion, though they need a bit of break-in time.
