I have a hifonics amp that apparently would blow up if i run it at 1 ohm so how would i set it up to run at 2 ohms. im trying to do anything possible to not run 4 ohms. thats too much. i am pushing a single voice coil sub

Why is 4 ohm too much? The lower impedance you drive an amp, the higher the THD.

When you wire subs or any other speaker, you will have three basic wiring configurations:
Single Speaker: Just wire in the single speaker to the positive and negative terminals.
Parallel Speakers: Wire the speakers in parallel by connecting the positive leads together and the negative leads together with all of the leads coming back to your amplifier. The total resistance is calculated by dividing reciprocal of the total resistance of all of the speakers together by the number of speakers. Thefore 4 Ohms per speaker divided by the number in parallel, if it is 2 speakers then the total resistance is 2 Ohms. 4 X 4 Ohm speakers would equal 1 ohm...
Series Speakers: Just add the Impedance of the speakers and chain them together positive to negative and then take the two end leads back to the amplifier.
Series - Parallel Speakers: You can combine the two method above to gain the resistance you want. Example: Though it is extreme, you could take two sets of the afore mentioned 4 parallel 4 ohm speakers and wire them in series for a total of eight 4 Ohm speaker wired in a series-parallel configuration for a 2 ohm load.
Good Luck and Enjoy the sound!

That depends on ohms of the speaker...
In series wiring, if you connect your amp to one speaker, the ohms rating is equal to that speaker's ohms rating.
