The impedance of the BS-1 Bass Shaker is 6 ohms. When used in a single unit configuration it must be hooked up to an amplifier that is either stereo or bridged mono, the same way you would connect a subwoofer. \u003cbr\u003e2. Before installing and use, please consult the amplifier manual for the impedance rating of your amplifier. Connecting 2 or 4 or 8 BS-1 bass shakers can be used in situations where more bass energy is desired or in larger applications. Connecting two in Series configuration will raise the impedance to 12 ohms, connecting 2 in parallel will lower the impedance to 3 ohms, and wiring 4 or 8 BS-1 in series-parallel will keep the overall impedance to 6 or 3 ohms. \u003cbr\u003e3. Before connecting the bass shaker amplifier, please consult the amplifier manual to verify it has the power capability that produce the wattage safely at various impedances.
