What the product is and who it is for

The DS18 GEN-X5.7 is a pair of 5x7 inch three-way coaxial car speakers rated at 4 ohms. They suit owners replacing factory units in standard oval openings who want clearer mids and highs without adding external crossovers or amplifiers.

Capacity and headroom

Each speaker handles 50 watts RMS continuously and peaks at 150 watts, with 85 dB sensitivity and a quoted 78 Hz to 20 kHz frequency response. The 150-watt maximum gives headroom for dynamic passages, though deep bass below 78 Hz will need a separate subwoofer.

What the bundled accessories

The package includes two speakers only; no grilles, wiring harnesses, mounting brackets or tuning software are supplied. Buyers must provide their own speaker wire, connectors and any spacers required for the 205 by 125 mm cutout and 53.8 mm mounting depth.

Questions about this item

Will the 4 ohm impedance and 50 W RMS rating work with my factory head unit?

The 4 ohm impedance matches most factory head units, and the 50 W RMS rating means the speakers will play cleanly at moderate volumes without needing an external amplifier.

How can I confirm the speakers are reproducing the full 78 Hz to 20 kHz range after installation?

Play a frequency sweep test tone; you should hear output down to the rated 78 Hz low end and up to 20 kHz without audible gaps or distortion.

Does the pair include mounting hardware or do I need to buy screws and adapters separately?

The box contains the two coaxial speakers with integrated 28 mm and 9 mm Mylar dome tweeters; mounting screws, brackets or wiring adapters are not included and must be sourced separately.
