The ButtKicker Wireless Kit (model BK-WCK) is designed to shake one three-seater couch or, one love seat, or, one or potentially two home theater seats, if the backs legs of the two home theater seats are close enough to both fit on the ButtKicker Advance Mounting Kit plate which is approximately 8 ½ “ wide. (Please note that some large and or very heavy couches, especially those that have hide-a-beds or heavy reclining seats at both ends, may require two Wireless Couch Kits. This is rare but can happen.)
The ButtKicker Wireless Couch Kit comes with one BKA300-P amplifier, 300 watt @ 4 ohms with integrated wireless receive, wireless send unit, one ButtKicker Advance transducer (model BK4-4), one ButtKicker Advance Couch Mounting Plate (model BK4-CMAK) and five RI-4 rubber isolators. The BKA300-P is not sold separately and only one ButtKicker Advance transducer can be powered by the BKA300-P amplifier.
The ButtKicker Power Amplifier (model BKA1000-P) can power up to eight ButtKicker equipped individual seats.  Individual home theater seats can be powered with one ButtKicker Advance (model BK4-4) or two ButtKicker mini concerts (model BK-mini-CT) or two ButtKicker mini LFEs (model BK-mini-CT). Please not that even if home theater seats are clipped together that each individual seat will need to have ButtKicker units installed in them.
Wiring diagrams and seat installation information can be found here.
Rubber isolators, either the larger RI-4 isolators or the smaller RI-K28 isolators are strongly recommended to be used instead of, or under, the feet of home theater seating for optimal performance.
It is not recommended to power a home theater seat with just one ButtKicker mini-LFE (model BK-mini-LFE) or one ButtKicker mini-Concert (model BK-mini-CT).
