I have 2 1200 watt amplifiers and 1 600 watt amplifier and 2 dual 2 ohm 1500 watt rms subwoofers. I was wondering if I could combine all of the amplifiers power somehow and have 3000 watts running to both subwoofers at 1 ohm instead of just using 2 amplifiers and having 1200 watts going to each subwoofer at 1 ohm?? If this is AT ALL possible someone PLEASE let me know how to do it.
I know some of the new power series amps from rockford, as well as some of the kicker amps, let you hook up identical amps together to drive a single output with the power of both amp's combined. I'm sure some of the other manufacturers make them too. But this only gives you a single output so it wouldn't help in your situation even if you had amps with this feature.
You will not be able to combine the power of all three amps, for many reasons, but the first of which is that each voice coil has to see the exact same signal and the exact same output level. Unless the amps have digital gains (+ & - buttons as opposed to a knob) then it is technically impossible to have the exact same amount of power going to both voice coils. Even then, you have other factors in play such as amp efficiency, damping factor, signal to noise ratio, THD, etc. that will all make it impossible to match up (or at least proportionally divide) the power of the amps.
