Question about Ohm Car Audio & Video
If you run one sub with the DVCs in parallel, you would get 2 ohms. If you run both subs with all DVCs in parallel, you would get 1 ohm.
If you run both subs with DVCs in parallel and subs in series, you would get 4 ohms.
If you run both subs with DVCs in series and subs in parallel, you would get 4 ohms.
If you run one sub DVCs in series and the other sub DVCs in parallel and both subs in parallel, you would get 1.6 ohms but the subs would not be balanced.
If you run both subs on only one coil and the subs in parallel, you would get 2 ohms (but only if the individual coils are rated for the full power)

SOURCE: how can i get a
A normal wiring setup to produce a 4-ohm load is what you usually see - each speaker is wired to one channel of the amp. This is series wiring. To get a 2-ohm load, you need to wire in parallel. Here's how:
Take sub A and wire the positive terminal to the positive terminal of channel 1 on the amp. Wire the negative terminal of sub A to the negative terminal of channel 2 on the amp. For sub B, it's the opposite - positive terminal of sub B to the positive terminal of channel 2, and the negative to the negative terminal of channel 1. That's parallel wiring, and will produce the 2-ohm loading (and subsequent increase in output) that you're seeking.

If you have 2 subs that are 2 ohms, the final impedance will be either 1 ohm if they are wired in parallel or 4 ohms if they are wired in series. You cannot get a final load of 2 ohms. Unless your amp is stable down to 1 ohm (many amps are not), your best solution would be to wire the subs in series, positive of one sub to the negative of the other sub, and the remaining positive and negative to the amp. Yes, this will result in a 4 ohm load and the amp power will be reduced. But it is better than destroying your amp with too low of a load, and the subs will work fine, just not as loud.

You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.
