If you had 4 single voice coil speakers you can create either of those 2 ohm or 4 ohm setups. If you run 2 of them in parallel you will get the 4 ohms. If you run 4 of them in parallel you will get the 2 ohms. In parallel I mean that you connect the positives together and run them to the positive on the amp and the connect the negatives together and run them to the negative on the amp. Let me know if you need more help. Good Luck.
