(2) W65K9D2 6.5" 1000 Watt Car Audio Subwoofers + Mono Amplifier + Amp Kit

A full bass system built around two compact 6.5-inch subwoofers: two K9 W65K9D2 subs, a dB12 mono amplifier, and a 4 gauge wiring kit. Each sub handles 250W RMS (CEA rated) through dual 2-ohm voice coils, and the dB12 puts out 500W RMS at 2 ohms (Dyno Certified). Wire each sub's coils in series for 4 ohms, then both subs in parallel for a 2-ohm load, and the amplifier delivers its full rated power.

The appeal of this combo is the size. At 5.94 inches cutout and 4.17 inches deep, these subs fit in doors, kick panels, under seats, and small custom enclosures where 8-inch or larger drivers are not an option. The K9 platform still packs a 66 oz double-stacked magnet, a 2-inch ASV voice coil with USA-made OFC wire, and a cast aluminum basket into each driver. The dB12 amplifier accepts balanced and unbalanced RCA inputs, has a bass remote for dash-level control, and runs a subsonic filter and adjustable bass EQ. The RWK41 wiring kit includes 17 feet of 4 gauge power cable, a 100% copper twisted-pair RCA, and all connectors for a clean install.
