I just received 4 Aura Bass Shaker Pros today...I am planning on attaching 2 to my main sofa and 2 to my loveseat. I was planning on using 2 Y-cables to split the LFE signal from my Yamaha RX-V1400. I will use one Y-cable to split the signal to my sub and use the other Y-cable to send a signal to the left and right channel of an old Kenwood receiver. I was then going to run two Bass Shakers in series off each of the left and right channels. Question...does splitting the LFE signal cause any degradation to the signal? Does anyone have any other suggestions on the installation?
