4 amplifiers to drive 1 pair of speakers?


Hi

Sorry I am still quite a young audiophile (less than 1 yr old)
Was wondering if its possible to use 4 amplifiers (eg 300b which is quite low powered) to drive a pair of speakers? 

I.e. pre amp output --> Y splitter into 2 different 300B amplifiers for each channel. Each amplifier can take either the top 2 or bottom 2 binding posts of the speaker.

My speakers are 90db 8ohm (more like 4ohm in real life), and im afraid that 2 300b PP amplifiers ~18W class A is insufficient.

Thanks!

@thegreenman.... You are correct to worry about Impedance dips.  It does somewhat matter about where (what frequency) they are, but the real problem is to try to get an impedance/phase sheet on your speakers.  Normally impedance dips are accompanied by phase angle dips.  This is where many many tube amps crap on themselves.  
I read that each speaker had 2 binding post?  So yes, assuming that you are running them as mono's, you could conceivably run your  amps that way.
