43DSC504 2-Pack [Used]

The Kicker 43DSC504 is a 5.25-inch two-way coaxial speaker built to replace tired factory drivers with real power headroom, rated for 200W peak (100W each) and 70W RMS (35W each) on a 6 to 35W RMS recommended range per channel. A rigid polypropylene cone paired with a UV-treated foam surround holds its shape through heat and repeated use, while the stamped steel basket keeps the whole assembly rigid instead of flexing under bass output. EVC (Extended Voice Coil) technology extends coil travel for cleaner sound at higher volumes, and the 1/2-inch zero-protrusion polyetherimide tweeter delivers crisp highs without adding depth that could interfere with factory grilles. A shallow 1.875-inch top-mount depth and a 4.50-inch cutout diameter mean this pair fits into most factory 5.25-inch locations without extra brackets or spacers. Frequency response runs 45 to 20,000 Hz with a 90dB sensitivity rating, and the 4 ohm impedance matches typical factory head units. Grilles are included for a finished look once the speakers are mounted. This pair works well in door or dash locations where a low-profile speaker is required.
