NO! unless the amp is "strappable", you WILL fry it.

There are two ways, and two ways ONLY to connect two amplifiers to one speaker:

Strappable amplifiers - both amps to a single coil
Dual voice coil woofer - one amp to each coil

Attempt anything else, and SOMETHING will give, and in a pretty spectacular way!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

No. But one amp at 1 ohm will make the SAME power as two amps at 2 ohms. In fact, since FEW amplifiers actually DOUBLE their total output when halving the impedance like that (from 550 at 2 ohms to 1100 at 1 ohm), it is quite likely that you will get a few more watts with one amp per coil. Likely the amps are a bit more than 550 watts, loaded at 2 ohms. What amps are they?

I PROMISE you, you will never notice the difference in output, as it will likely be well less than one half of one dB...
