Two dual 2 ohm subs = .5 ohms wired parallel and 2 ohms wired in a series / two dual 4 ohm subs = 1 ohm wired pallallel and 4 ohms wired in a series / one dual 2 ohm sub = 1 ohm wired parallel and 4 ohms wired in a series / one dual 4 ohm sub = 2 ohms wired parallel and 8 ohms wired in a series......this means if you have two dual 2 ohm subs or if you have one dual 4 ohm sub you are not going to be able to get a 1 ohm load.......running parallel on a dual coil speaker is both positives are ran to the positive on the amp and both negatives are ran to the negative on the amp.....running in a series is the positive terminal from one coil ran to the positive on the amp and the negative terminal on the other coil ran to the negative on the amp and having the remaining open positive and negative terminals connected to each other with a jumper wire

That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.
