Using 2 integrateds to bi-amp?

Maybe this is a really dumb idea (if yes, please tell me why). Would it be possible to connect 2 integrated amps by Y connectors to a single source (e.g., TT or CDP)then use 1 to drive the L & R tweeters and the other to drive the L & R woofers of a 2 way speaker system? I have two integrated amps but don't have $ to go mono-blocks + pre-amp.
Well, I suppose "effort" in lieu of $ is my justification plus I kind of enjoying messing around with this stuff. On the other hand, is it that much different than trying to integrate a powered sub-woofer?
We need more info. Same amps? Different? Which ones? I would go to Integrated "A" with all sources then line out (fixed tape out not variable preout) to Integrated "B".

Integrated A = the one with a better sounding preamp section if A/B are different

If the power levels are different on the amps the higher one to the woofers of course.

Good luck!

Sorry but I only read all your follow ups after I my first post. Yes go horizontal and use the tube integrated as "A" in my first post and use the tape out to the other amp. Tubes on the HF, SS on the LF. Don't worry about the SPL thing, adjust it to the way you like it. You put the amount of salt and pepper you like on your food (if any) and not what someone else says right? Also don't worry about what Kal says he thinks passive(horizontal) bi-amp is a waste. Those of us that have it know better. It sounds better at all volume levels especially in an optimum passive setup where the amps are power amps and are the same input impedance, gain and sensitivity. LF having about 2X the HF amp is good depending on the actual X-over frequency and type of speakers. Good luck-please report back.

Electroid - see my reply to S7horton but yes, 2 different amps. Jolida 502B (60 wpc) & a mid '80s Yamaha R1000 receiver (100 wpc). Was thinking exactly as you suggest to run upper range drivers with the JoLida and lower range drivers with the Yamaha.

Thanks for your suggestion. I do indeed have a "tape out" on the JoLida (an input to my Nakamichi tape deck that I don't use much). Is this what you have in mind? (not sure what 'fixed tape out not variable preout' means). If yes, it does seem better than running Y splitters to each amp from all sources. If this works, I'll buy you a (virtual) beer and shop around for something better to replace the Yamaha. Thanks again.
Yes, use tape out on the Jolida. Tape out is "fixed" meaning regardless of where the volume is set on the Jolida the level coming out of the tape out is the same. This way it doesn't affect the volume on the other amp.

It will work fine and as you said no Y adapters needed. Let us know how it works out. Also, enjoy the flexibility of the two volume controls you'll have to make things sound to your liking.

If you want to be anal you can connect a tuner, tune it to "dead air" and measure the outputs of your amps with a voltmeter (set to AC) and tweak the volume control(s) to equal the output of each amp. You'll at least have somewhat of a reference for where each volume control is in relation to the other for equal output. In the end I still say set it the way you like it!
