That is why today, we will talk to you about which is better overall, and which is better in specific situations too.
When you are buying a subwoofer, and you see that it is rated as a 2 ohm subwoofer, this means that the resistance is level at 2 ohms.
This, in turn, means that an amplifier is able to feed it more power without too much resistance. On the flip side, this does mean that it will consume more power due to its smaller resistance.
This can lead to lower quality bass. However, its lower electrical resistance does mean that it will produce a louder sound than one that has higher electrical resistance, this means that a 2 ohm subwoofer will be louder than a 4 ohm subwoofer. So on the positive side, you get a louder result, but on the negative side, you get poor quality of sound due to the power consumption.
Subwoofers with a resistance rating of 4 ohms mean that they have higher resistance, and so, it will reproduce less sound due to its higher resistance. Sadly, this means that it does not deliver a loud sound. But, on the flip side, it does consume less power from an amplifier than a 2 ohm does. So will reproduce sound that is much more compact, and as a result of this you will get a higher quality of bass.
These subwoofers will typically last longer than a 2 ohm subwoofer, and they do produce a better base, yet they lack the power to produce very loud sound. Really, it is more of a decision if you want bass and quality over how loud the sound is, or if you would prefer your subwoofer to produce more noise and less bass and quality.
A lot of people will have subwoofers in their cars, and you can use more than one. You will need to check the wiring option to determine the resistance. You can wire them in a series, or parallel.
If you do the former, you will wire them one after the other with negative wired to positive. If you do the latter, then you simply wire the terminals of one subwoofer to the similar terminals of the other, with negative wired together, and positive wired together. If you wire them in series, you will get a higher resistance, so you will get more bass.
This means that if you were to wire 2 subwoofers that have a resistance of 2 ohms each, it would add up, and you would get a total resistance of 4 ohms. Now for the sensitivity, i. Now at. So to put it simply, the difference is not that great if say you are planning on having a few subwoofers. It will mostly produce the same sound if they are run at the same wattage and will make little difference to the sound produced, the main difference being maybe the price.
Home Technology Difference between 2 ohm and 4 ohm Subwoofers. Difference between 2 ohm and 4 ohm Subwoofers. The vast majority, yes. When we install 4-ohm speakers, they can be from a different brand, have different sizes or power, and also impedance can be different. However, this is rare. When you wire 4-ohm front speakers and 2 ohm rear speakers to the 4 channel amplifier, you have to be careful with the power level of these 2-ohm speakers to not overload transistors and not damage the amplifier.
Another point to consider is the volume level of these speakers. As we already said, 2-ohm speakers can play louder with the same power, so in our example, when mixing 4 ohm and 2-ohm speakers , you can hear too much from the back of the car.
If you want to have a different impedance in the front and the back of the car and one amplifier, make sure 4-ohm speakers have twice as much power as 2 ohms. In this case, you will ensure leveling out amplifier output to all channels. Nevertheless, the best and safest way is to use all speakers in the car with the same either impedance.
Your system will be stable, and you will not have to make too many adjustments to make it work. Subwoofers are different, and when you see a typical car audio system, the speaker with a different usually lower impedance will be the subwoofer.
They can work with 4, 2, or even 1 ohm in some cases and also can have either one or two voice coils, so the number of variations in subwoofer connections is much higher than for the typical car speakers. The most significant factor in the subwoofers is their ability to create loud and strong bass, and that requires a lot of power.
The more powerful the subwoofer, the lower impedance it will have. A 2-ohm subwoofer will play louder than 4 ohms with the same power, but how strong bass will be generated also depends on the enclosure type. If you want to make a really loud bass in your car, buy a 2-ohm subwoofer and a large power station to supply enough current.
However, with the impedance reduction, you also reduce the quality of the bass, so you have to prioritize either music quality or loudness. A similar approach is for subwoofers with dual voice coils. Although you physically have one speaker, the connection with the amplifier is the same as for the two independent woofers. Depending on how you will connect it, you will determine the overall resistance of the dual voice coil subwoofer. When you connect both 2-ohm voice coils in series, the impedance will double, and it will become one 4 ohm speaker, or when you will wire them in parallel, the impedance will be divided and will be 1 ohm.
To decide about subwoofer impedance, you have to decide which bass quality you want to achieve, and this is the starting point.
If you wish to hear hi-end perfect kicks but with a moderate volume, go for a 4-ohm subwoofer. By doing so, you can still connect several subwoofers in the car and further increase the quality of the lowest sounds.
