Hertz Dieci DCX 100.3 4" 10 cm Enceintes coaxiales 2 voies pour porte/dashboard auto 30 W RMS Paire

The treble is surprisingly crisp for a 4-inch speaker, and the 60W handling means they don't strain even at higher volumes. I swapped out my factory ones and the clarity on vocals and mids is night and day. Wiring them into the dash was straightforward, and they fit perfectly with the standard 10cm

I've had these in my dash for a few weeks now and the 60W peak power handling really wakes up the highs without distortion. The 4-inch size was a perfect direct fit for my factory locations, and the soundstage feels much wider than I expected from such small speakers.

The 4-ohm impedance pairs perfectly with my factory head unit, and the 60W peak handling gives them plenty of headroom without distortion. I’ve had them in for two weeks now and the midrange clarity on vocals is noticeably better than the stock paper cones.
