(2) K5 W8K5S4 8" 800W 4 Ohm Car Subwoofers + Mono Amplifier + Amp Kit

Two K5 W8K5S4 8-inch subwoofers paired with a dB11 mono amplifier and an 8 gauge wiring kit. Each sub handles 200W RMS (CEA rated) through a 4-ohm single voice coil. Wire both in parallel for a 2-ohm load and the dB11 delivers its full 350W RMS, Dyno Certified. The 4-ohm impedance also lets you run these from a bridged 2-channel amp if that better suits your system layout.

The K5 subs use 1.5-inch 4-layer OFC copper voice coils from Japan, fiber-reinforced paper cones, thick foam surrounds, and 30 oz magnets in cast iron baskets. A 7.16-inch cutout and 3.54-inch depth make them compact enough for under-seat and rear-deck installs. The dB11 runs Class D topology with a bass remote, balanced and unbalanced RCA inputs, and adjustable low pass and subsonic filters. The RWK81 wiring kit includes 8 gauge power cable, a 100% copper RCA, and all fuses and connectors. The 8 gauge wire is properly matched to the dB11's current requirements, so you get clean power delivery without oversized cable.
