Well if you know electronics, you know ohms is the load a resistor places on an electrical source...same thing goes for speakers. If you send 22 watts thru a 6 ohm speaker, it'll show more resistance, requiring more power to play at the same output than a 4 ohm speaker. With car amps and subs, people use 2 ohm, 4 ohm, or even 8 ohm subs and amps are generally rated at 4 ohms; in the past few years they've given RMS ratings at 2 ohms as well. The RMS on your HU is based on 4 ohms. A 4 ohm load compared to a 2 ohm load will require twice as many watts, or at 22 watts RMS, if it were perfectly efficient, the 2 ohm speaker would see 44 watts (6 ohms would see about .25 times less, so 16.5 watts). But the resistance of the speaker varies all the time, its never a constant.
The OEM wires will be fine, the only reason you'd need to change those is if you beefed up the power supply significantly (would have to go to a smaller gauge and speakers that could handle it) or just wanted to upgrade to higher quality.
I don't know if that's exactly right, but I think it is...just kind of going from memory on things that I haven't done in awhile. I should be going to school for engineering instead of economics........
