I think that such an idea is great. Having said that, i would emphatically state that 60 wpc is not enough power to achieve quality reproduction of low frequencies in my opinion based on quite a bit of experience in this area.
With that in mind, i've done something very similar but gone to an extreme in the method that i chose. To try to sum things up briefly, i am actively tri-amping with six stereo amplifiers. The amps are set up to operate in what is effectively a monoblock format even though all 12 channels are in use. While i did so for multiple reasons, my primary goals were to increase dynamic headroom, achieve the ultimate in stereo separation and to spread out what is a very tough i.e very reactive AND very low impedance speaker load over multiple amplifier channels.
With the average impedance of the system hovering around 2 - 3 ohms per amplifer channel, i've got 2400+ wpc ( using the various amplifiers 4 ohm power ratings ) as things are currently arranged. I would realistically rate output capacity as somewhere around 3 KW rms per channel at the actual impedances that the amps see.
Using this approach, none of the individual amplifier channels are "pushed" as hard as they would be if i had them set up in a more conventional manner. On top of this, damping factor is doubled and there is no chance of ever clipping. While the amplification system has worked most excellently once i was able to get things dialed in, i just need to find a way to quit demolishing specific sections of the speakers. I've still got a ways to go on this, but it's pretty much been both a "labour of love" and a learning experience at the same time : ) Sean
