Putting two shakers in series across the output presents an 8 Ohm load.
Adding a 4 Ohm shaker in parallel presents a 2.67 Ohm total load.
Adding another 4 Ohm shaker in parallel drops the overall impedance down to 1.6 Ohms.
***That might be too low of an impedance for the amp to handle! It could distort, shut down, or damage itself if not self-protected properly.***
connected shakers would receive 4 times more power than the series connected shakers in this configuration though)
Instead you could connect two shakers in series and then add the two parallel connected shakers in series with that, making a total of 4 + 4 + 2 = 10 Ohms.
That's an easier load on the amp, but your overall power output capability will drop from 230 Watts down to only 92 Watts. That might be too low for what you need.
(Also, now the series
connected shakers will receive 4 times more power than the parallel connected shakers in this configuration. The opposite of the first configuration)
