Changing 4-ohm speakers to 2-ohm speakers is a good way to get more power to your speakers, assuming that the amplifier feeding the speakers can handle the 2-ohm load. Whether it is a dual speaker with 4-ohm voice coils or two separate 4-ohm speakers, how you wire them for 2 ohms is basically the same. To get an impedance to drop from 4-ohms to 2-ohms, the speakers have to be wired in parallel. Again, make sure your amplifier can handle the load before doing this. If not, it will overheat and could be damaged.

Instructions
things you'll need:
- 2 4-ohm speakers
- Speaker wire
- Wire cutters
- Wire strippers
- 1Place both speakers in their proposed locations. Cut a piece of speaker wire that will reach between the terminals of both speakers.
- 2Strip 1/2 of an inch of insulation off of the two ends of both wires. Looking at one end of the wires, locate the negative and positive wires. For clear speaker wire, the positive wire usually has a white stripe on it. For red and black speaker wire, the red wire is positive.
- 3Connect one end of the positive wire to the positive terminal of speaker 1. Connect the other end of that wire to the positive terminal of speaker 2. Then connect one end of the negative wire to the negative terminal of speaker 1. Connect the other end of that wire to the negative terminal of speaker 2.
- 4Connect the positive and negative terminals of speaker 1 to the amplifier to run the speakers. This wiring configuration places speaker 1 and 2 in parallel, which reduces their 4-ohm resistance to 2 ohms
