I always assumed the signal impedence would be altered tying in a second component to a single set of outputs (signal devided in half). I also assume you could add another main out and tie that into circuit (rather than simply pig tailing 2nd out) to maintain signal integrity. Perhaps I'm wrong, some more technically savvy member should know.
How to hook up 2 amps from one set of pre outs?
I have a Simaudio I-5 (70W X 2) which is not quite powerful enough to truly push my (Inefficient yet wonderful) Egglestonworks Fontaine's. I am considering adding a slightly older Celeste SimAudio 4150se into my system (150W X 2, versus 70W X 2). Should be enough power. I have a TBI VI powered sub which is currently being fed it's signal from Pre Outs on I-5. How do I connect the 4150se from Pre Outs and my TBI sub at the same time? Can I use a Y Connector on PreOut's? Or is this a no no.
