2 Excelon Kac-x401m's, 1 4 ohm coil?

Hello fello car audio enthusiasts. I have 2 Kenwood Excelon Kac-x401m's (600rms @2ohm). Assuming  the signal is sufficient and the gains are evenly matched, can they be used on a single 4ohm coil? I have a custom made TC Sounds/Audiomobile MASS 15 on its way. I would rather use the two amps,  than buying one larger amp. All feedback welcome. Thanks!

NO. Unless the amp is designed to be "strapped", you will cook it in VERY short order. If you have a dual voice coil woofer, you can run one amp to each coil, but with one coil, you are stuck with one amp.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."

I hoped I would have more replies. I've beed researching the whole "strapping" thing. So far all of the strapping amps I've looked at feature the strapping circuit not to make two amps capable as functioning as one per say, rather so that both amps' gain/boost/subsonic/and other signal manipulations will affect boths amps as one. Other than that all of the speaker wiring between the two amps seems pretty straight forward, positive out of amp 1 to sub +input, negative out of amp 1 into - of amp2, positive of amp 2 to sub -input. Just like inverting a channel when bridging. It seems the "strapping" thing is to make sure all of the amp settings are exactly the same. However without a strapping circuit this could be accomplished with an O-scope and a multimeter. So the question I have is: Is there any electrical reason this cannot be done? Does anyone know an amplifier super-genius I can ask?
