You’ve got your four 12” subs and you’re ready to rock, but what size amplifier do you need to power them? It’s not as simple as just buying the biggest amp you can find, you’ve got to consider a few different factors to make sure you get the right amount of power for your subwoofers. In this article, we’ll go over everything you need to know about choosing the right amp for your four 12” subs.
First, you need to consider the RMS power rating of your subs. This is the amount of power the subs can handle on a continuous basis without being damaged. You’ll want to look for an amp that can provide at least as much power as the RMS rating of your subs.
Next, you need to consider the peak power rating of your subs. This is the amount of power the subs can handle for short periods of time without being damaged. The peak power rating is usually much higher than the RMS rating, so you’ll want to make sure the amp you choose can provide at least the RMS power rating of your subs, if not more.
Finally, you need to consider the impedance of your subs. This is the amount of electrical resistance that your subs have.
When it comes to choosing the right amplifier for your car audio system, the first thing you need to consider is how many watts RMS your subwoofers can handle. For example, if you have four 12-inch subwoofers that can handle up to 500 watts RMS each, then you’ll need an amplifier that can put out at least 2,000 watts RMS. Now, you might be thinking that you can just get an amplifier that produces more than 2,000 watts RMS, but that’s not necessarily the best idea.
You see, when it comes to car audio, more power isn’t always better. In fact, if you get an amplifier that produces too much power, you could actually end up damaging your subwoofers. So, how do you know how much power is too much?
Well, that’s where your subwoofers’ RMS rating comes in. You see, the RMS rating is the amount of power that your subwoofers can handle on a continuous basis. So, if you get an amplifier that produces more than 2,000 watts RMS, you’re likely to blow your subwoofers.
Of course, there are other factors to consider when choosing an amplifier for your car audio system, but power is the most important.
Subwoofer amplifier calculator
If you’re looking to add a subwoofer to your car audio system, you’ll need to make sure you have the right amplifier to power it. But how do you know what size amplifier you need? There are a few things to consider when choosing an amplifier for your subwoofer.
First, you’ll need to know the power handling of your subwoofer. This is the maximum amount of power the subwoofer can handle before being damaged. Next, you’ll need to know the impedance of your subwoofer.
This is important because you need to make sure the amplifier can handle the impedance of the subwoofer. Finally, you’ll need to know the sensitivity of your subwoofer. This is the measure of how much power the subwoofer needs to produce a certain sound level.
Now that you know all of that, you can use a subwoofer amplifier calculator to figure out how much power you need. Just enter the specs of your subwoofer and the calculator will do the rest. Now that you know how to choose the right amplifier for your subwoofer, you can get the most out of your car audio system.
What amp do I need for 4 speakers?
If you’re looking to connect four speakers to an amplifier, you’ll need to make sure the amp can handle the impedance of the speakers. Most car speakers are 4 ohms, so you’ll need an amp that can handle that. You’ll also need to make sure the amp has enough power to drive all four speakers.
A good rule of thumb is to get an amp that can deliver 50 watts RMS to each speaker.
Can you run 4 subs on a 4 channel amp?
It is perfectly fine to run four subs off of a four-channel amplifier. In fact, many car audio enthusiasts believe that four subs sound better than two subs. The main reason for this is that four subs provide a more well-rounded and full sound than two subs.
Additionally, four subs can provide more bass than two subs.
What size amp should I get for my subs?
If you’re looking to add a little extra bass to your music, then you might be wondering what size amplifier you need to power your subwoofers. The answer to this question depends on a few factors, including the wattage of your subs, the sensitivity of your subs, and the overall power output of your amplifier.
To start, you’ll need to know the wattage of your subwoofers.
This information can be found in the owner’s manual or on the manufacturer’s website. Once you have this number, you can multiply it by the sensitivity of your subs. The sensitivity is measured in dB and is typically between 80-100 dB.
For example, let’s say you have two subwoofers that each have a wattage of 500 watts. If we multiply 500 watts by 80 dB, we get 40,000 watts. This means that your amplifier would need to have an output of 40,000 watts to properly power your subs.
However, it’s important to note that most amplifiers are not capable of putting out their full power output for sustained periods of time. This is why you’ll often see amplifiers with a “peak power output” and a “RMS power output”. The RMS power output is the amount of power that the amplifier can safely put out for extended periods of time, while the peak power output is the maximum amount of power that the amplifier can produce for a brief burst of time.
How many amps do you need for a 12 inch sub?
If you’re looking to add a little extra bass to your car audio system, you might be wondering how many amps you need for a 12 inch sub. The answer isn’t as simple as you might think, as it depends on a few different factors.
First, you need to consider the RMS (root mean square) power rating of your subwoofer.
This is the amount of power that the sub can handle on a continuous basis. Most 12 inch subs have an RMS power rating of around 500 watts, but it can vary depending on the model.
Next, you need to consider the efficiency of your subwoofer.
This is how much power the subwoofer can convert into sound. A more efficient subwoofer will require less power to produce the same amount of sound as a less efficient model.
Finally, you need to take into account the impedance of your subwoofer.
Most 12 inch subs have an impedance of 4 ohms, but some models can be as low as 2 ohms. A lower impedance subwoofer will require more power to drive.
So, how many amps do you need for a 12 inch sub?
It really depends on the specific subwoofer that you have. A good rule of thumb is to multiply the RMS power rating of the sub by two to get the minimum amount of power that you’ll need from an amplifier.
How to Match a Car Subwoofer and Amplifier
Conclusion
If you’re looking to add some serious bass to your car audio system, you’re going to need a powerful amplifier to drive your four 12-inch subwoofers. But how much power do you need, and what other factors should you consider when choosing an amp for your subs? In general, you’ll want an amplifier that can deliver at least twice the power of your subwoofers’ RMS rating.
So, if your subs have an RMS rating of 1000 watts, you’ll want an amp that can deliver at least 2000 watts. Of course, there are other factors to consider as well, such as the impedance of your subwoofers and the efficiency of your car audio system. But if you’re looking for a quick answer to the question, “What size amp do I need for 4 12 inch subs?” the answer is that you’ll need an amplifier that can deliver at least 2000 watts of power.
