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.

a Y connector is fine. Another alternative is if your Sub has hi level inputs (as most subs do) you can connect it to your amp using those. Your sub may also have pre-outs that incorporate the Sub's x-over, and you can connect your 4150se using those outputs.

Or you can have a full length set of y cables built. I know audioquest has done them in the past; no reason why other manufacturers could not, if they do any custom work.

I just had a set of dual balanced cables made to bi-amp my speakers. Try Frank at Signal Cable, he made them for me.

you can add another set of main outputs on your preamp, if there is room.

I have a custom set of Y connectors [ 1 male to two females] that Audioquest made for me with their Emerald cable when I had this problem. Contact me if interested.
