I will be installing 6 new Aura Pro BassShakers and a SVS subwoofer soon. I may have to use two separate amps to drive the Shakers. This will mean splitting the LFE output signal three ways. Two to the Shaker amps and one to my sub. Will this weaken the signal to the three devices? I have heard people slitting the signal using a "Y" adaptor..but not three ways. Thank in advance!
