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.

Why not run the sub w/ speaker cable instead of rca?

Not sure if your amp has two sets of binding posts, but if it does not, simply run two sets of speaker cable... One set going to the mains, the other set going to the sub. This way, you do not have to worry about Y connectors or possible problems w/ said configuration.

IMO, i've found connecting a sub this way reaps better sonics than using RCA cables, although i do realize that every system is unique in its idiosynchrasies.

regarding what SNS said, I have heard the same. I was in a similar situation at one point and every knowledgable person I asked told me splitting the pre-out was a no-no.

Just my 2cents.
