I was wondering what the difference between say a 4 ohm speaker and a 2 ohm speaker is. I was looking at buying some Infinity Kappa 693.7i's but the head unit I have right now is my factory honda accord one. Will it run these 2 ohm speakers or must i go for the 4 ohm ones. ALso what is the difference in sound quality between the two, any help would be awesome.
Thanks Alasdair
btw looking to get 6x9's and 6.5 component system.
Assuming the water pressure (voltage) is the same, hose B will pass less volume of water (amps) than hose A.
It can be said that the resistance (similar to impedance, but impedance applies to reactive loads) of hose B is larger.
In terms of how this applies to car stereos, most HU's are already at their limits with 4 ohm loads, but introducing a 2 ohm load, you're not likely to have success.
In a matched system, there really shouldn't be any difference in sound quality per say. A 2 ohm load will draw more power from the amp (being a HU amp or external amp)than the 4 ohm speaker.
You really can't draw conclusions on volume based entirely on speaker impedance. Other factors are involved such as efficiency.
ohms are a measure of resistance. the lower the resistance, the more power the amplifier will produce. if the resistance is too low, the amp will burn up from too much heat/power
