The single 8-in shallow woofer is designed to deliver articulate mid-bass and surprising low-end impact from a 2.04 in mounting depth, letting it fit under seats or in OEM speaker locations. With 150W RMS handling and a 2-ohm nominal impedance, this driver is a compact solution for improving factory systems or adding a focused sub under the seat, and its construction targets durability and clean output rather than earth-shaking output.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow mounting depth:\u003c\/strong\u003e The 2.04 in mounting depth allows installation under seats and in tight door locations where conventional subs will not fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling:\u003c\/strong\u003e Rated 150W RMS (300W max), it accepts modest amplifier power for punchy, controllable bass without needing a large amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRibbed polypropylene cone:\u003c\/strong\u003e The inverted polypropylene cone with ribbing and an aluminum dust cap improves stiffness and transient response for clearer mid-bass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust suspension:\u003c\/strong\u003e High roll pressed-foam surround and NOMEX\/ROMEX spider assembly keep the motor stable for consistent performance at higher excursion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-ohm nominal impedance:\u003c\/strong\u003e The low impedance is beneficial for extracting more output from multi-channel car amps or for loading compatible mono amps effectively.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended enclosures:\u003c\/strong\u003e The driver works well in sealed systems from 0.2 cu ft to 0.6 cu ft, giving installers clear guidance for tuning in small enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe SWS-8Xi is aimed at vehicle owners who want better, tighter bass than their factory system provides but lack space for a traditional subwoofer.
