While designed for amplifiers, they can be used with many 4-ohm factory amplifiers and offer clearer sound and greater range than OEM speakers.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Diameter\u003c\/b\u003e: 4\" (101 mm) – compact size fits in typical door or dash openings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Impedance\u003c\/b\u003e: 4 Ohms – standard load for many in-vehicle amplifiers, balancing power delivery and damping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRMS Power Handling\u003c\/b\u003e: 40W – continuous power rating; use an amp that can deliver clean power without clipping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Power Handling\u003c\/b\u003e: 120W – peak capability for short musical transients.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSensitivity\u003c\/b\u003e: 84 dB (1W\/1m) – efficiency; higher values mean louder output from the same power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFrequency Response\u003c\/b\u003e: 80 Hz – 20 kHz – covers bass to treble; deep bass relies on the overall system, not just the speaker alone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRecommended High-Pass Crossover\u003c\/b\u003e: 90 Hz – protect the woofer and optimize integration with other speakers in a system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDesign\u003c\/b\u003e: 2-Way coaxial with woofer and tweeter – simple installation with full-range performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTweeter\u003c\/b\u003e: Mylar Balanced Dome – adds extended high-frequency detail with smooth response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWoofer Materials\u003c\/b\u003e: Paper cone, rubber surround, steel basket, Ba ferrite magnet – durable construction for daily driving conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVoice Coil\u003c\/b\u003e: 1\" (25.5 mm) ASV coil – robust for heat and excursion in a compact package.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOverall Dimensions\u003c\/b\u003e: 4\" diameter, 2.4\" depth; with grill: 5.28\" diameter, 2.46\" depth – installation footprint and grill compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e: 0.45 kg per speaker – lightweight for easy mounting in tight spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGrill Included\u003c\/b\u003e: Yes – protects drivers in aftermarket installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePair\u003c\/b\u003e: Pair – ships as a matched pair for common door\/dash installs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn a car audio build, the G4XI pairs a compact 4\" woofer with a 1\" Mylar tweeter to deliver cohesive, wide-range sound from a small footprint. The 4-ohm impedance and 40W RMS rating align with mid-power amplifiers, while the 80 Hz–20 kHz range provides clear vocals, detailed highs, and confident midbass. The steel basket and durable cone resist road-induced flex, making it suitable for mounting in doors or dashboards. A 90 Hz high-pass crossover recommendation helps tailor the system and protect the woofer from over-excursion. The included grill protects the drivers and preserves a clean aftermarket installation. \u003c\/p\u003e\n\u003c\/div\u003e","brand":"DS18","offers":[{"title":"Default Title","offer_id":49850242695396,"sku":null,"price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/2522\/9028\/files\/G4Xi-FRONT-PAIR_700x_67b0de76-4ed9-47d9-974f-4f6cfd065c34.webp?v=1789261697","url":"https:\/\/www.12voltoutlet.com\/products\/ds18-g4xi-gen-x-4-2-way-coaxial-speakers-40-watts-rms-4-ohm","provider":"12 Volt Outlet","version":"1.0","type":"link"}
