What is the difference between 4ohm and 2ohm

It's okay to overpower your subs a little bit, as long as the signal's distortion-free, because they're made to withstand occasional peaks well beyond their normal RMS rating. The sub and amp you need depends on what you want to hear. If you plan on listening to music at moderate volume levels or have a smaller car, a subwoofer with a lower power handling rating, say to watts, and a matching amp is a good combo. The ultimate goal is to have the amp send its full power to subs that can handle it.

The object of using different wiring options to optimize the impedance is to get the most power out of the particular amp and subs you have at hand. For more wiring specifics, check out our subwoofer wiring diagrams. If you want to get right into choosing a subwoofer, take a look at our top-rated and best-selling subs. The amp that I'm looking at is a 1, watt amp. Conservatively rated at 1, watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 1, watts at max power output.

Would this be a good amp to power both subs? If so, can I connect a pair of 1 inch tweeters to offset the remaining power being given from amp to speaker? What else if any can I connect to the amp and use its maximum power? I can wire the subs down to 2 ohm correct? I would like to know if I have a 12" dvc subwoofer rated for watts rms at 4 ohms, will the rms watts changed when it is then wired in parallel to push 2 ohms? Or does the rms watts always stay the same wether it gets wired at 2 ohms or 8 ohm?

I got 2 jl audio 12w v2-d4 with rms each and a memphis mcd at 2 ohms is rms is this a good set up and if so whats the best way to wire them up?

I have a Kia Soul with a all 4 ohm Rockford Fosgate door speakers, which replaced 4 ohm factory speakers. Same factory head unit. Will the fact that this sub is 2 ohms clash with my setup? I would like to start by saying cruthfield is on OG status and l always learn something new when l search for information.

Now lets get into the dish Will this all work together? Are there any glaring issues with this that would be damaging to any of these components? If so is there a way to minimize the risk or make it work together using all of these components?

I just got off the phone with one of your reps and was told that a 4 ohm sub RF P3d could only be wired to 1 or 4 ohm and I wanted it to be wired to 2 ohms. I am currently running two mtx on a taramps smart 3k. I'm considering getting them reconed with upgraded parts but they told me the only coils they have available for it are dual 1 ohm coils instead of 4ohm.

How would that effect the sound and power handling of my subs? Our subwoofer shopping guide will help you determine which kind of subwoofer and bass system you need, to get the sound you want.

There is a lot more that matters. Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass.

On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass. Thus, make your choice depending on the kind of bass you want.

What if a subwoofer has dual voice coils? So which is better between a 2 ohm and 4 ohm subwoofer? Click Here to Leave a Comment Below 0 comments.

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. On the other hand, if you want to create thunders in your car and make it shaking with every kick, you should consider a 2-ohm subwoofer or even 1-ohm. And for even more bass, you can connect multi subwoofers in parallel to reduce impedance and make them play even louder, but this approach is right when the decibels are the only priority.

Generally, you should be fine when replacing 2-ohm speakers with 4-ohm speakers. But keep in mind that 2ohm and 4ohm speakers have different power requirements.
