The RW8CA combines an 8' sealed subwoofer and a built-in amplifier rated at 150 watts RMS (600 watts peak) into a 2.7' slim enclosure that tucks under most seats, and the biggest reason to buy is its easy installation options - including high level inputs with auto turn-on - which let it integrate cleanly with factory or aftermarket radios.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact sealed enclosure:\u003c\/strong\u003e The 2.7' thin enclosure fits under most vehicle seats while preserving trunk and cabin room.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in amplifier:\u003c\/strong\u003e A PWM MOSFET power supply and monoblock output provide 150 watts RMS at 2 ohms for consistent low-frequency output without a separate amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible inputs:\u003c\/strong\u003e Low level RCA and high level inputs with auto turn-on simplify wiring to either aftermarket or factory head units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable tuning:\u003c\/strong\u003e Low pass filter (50Hz-150Hz), phase switch (0\/180), and 0-18dB bass boost at 45Hz let users tailor the bass to their vehicle and preferences.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection circuits:\u003c\/strong\u003e Built-in thermal, short and overload protection help protect the amplifier and speaker during heavy use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote control:\u003c\/strong\u003e A wired subwoofer level remote and soft delayed remote turn-on make on-the-fly level adjustments easy from the driver seat.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe RW8CA is aimed at drivers who need more bass but have limited space: commuters, small-cabin cars, and anyone who wants a tidy under-seat install without a bulky enclosure or separate amp.
