Alright i have a sony 1100 watt sub with a single 4 ohm voice coil. Is it possible to run it at 2 ohms on my 1200 watt 2 channel legacy amp

The amp is 2 ohm stable

So You Have a 1200 watt amp, and a 4 ohm voice coil and you want to run it at 2 ohm's if I am fowlling you correctly ? if the voice coil needs 4 ohm's (or rated to run at 4 ohm's correct?) and your amp will only put out 2ohm's if this is what you saying correct ?, it will work but not up to the MFG specifications, if its lower it should work if it was the other way around it would not ,it would cause an Line Load over heat and fail. if Iam fowlling you , hope this is some help take care

The only way to do it is buy another 4 ohm sub and wire it in parallel with the first sub. The draw back is the power in a parallel circuit is split in half between the two identical loads so only half of the rated power will get to each sub.
If you could get two 1100 watt subs @ 1 ohms and wire them in series or two 2200 watt subs @ 4 ohms and wire them in parallel, then full power would run to both subs .
Note: Loading an amp at lower ohms WILL increase heat, an amps worst enemy. Cooling methods should be practiced.
I'm going to assume the wattage ratings you've provided are not RMS, which is what you should really be using for measurement as it is most accurate to use. Rarely does an amp hit max.

Ur 2 channel legacy amp will clip like theres no tomorrow if u ran it bridged to lower than 4 ohms. Even at 4 ohms bridged, it has issues sometimes.

No. It is not possible to run your sub at 2 ohms. The final impedance load is solely dependent on the impedence of the speakers. It has nothing to do with the amp. The amp, however, is rated at an impedence that it is stable running.
For example, if you hook a single, 4ohm voice coil sub up to your amp, the amp will put out the amount of power for which it's rated at 4ohms (the standard power output impedance). If, for example, the subwoofer had a DUAL 4ohm voice coil, then your connection options would be to either run the sub in parallel, resulting in a 2ohm final load, or in series, resulting in an 8ohm final load.
Running it at 2ohms, your amp would put out the power wattage that it's rated at 2ohms (if it's stable in running 2ohms).
Running it at 8ohms, your amp would put out about half of what the 4ohm rating is.
To determine what the amp is rated as, you need to look at its wattage specs. 4ohms is the standard wattage rating. Most amps can run at 2ohm stereo, but only some can run at 2ohm mono (bridged) and lower.
I hope this helps!

If I understand you correctly, your amplifier has the nominal output of 2 ohms and your speaker is 4 ohms.
If you connect them directly, the current that flows into the speaker will be half. Therefore, the power you get will be 550 watts.

It all comes down to the amp. If the amp will run in 2ohm then yes. But I dont think Legacy amps will.
