If you’re a music lover, then you already know the subwoofer. A subwoofer plays an important role in an audio system.
A subwoofer is designed to reproduce low-frequency sounds. It would be best if you had electricity to run the subwoofer.
In today’s article, I’ll guide you in detail on how many watts is a good subwoofer, how to know how much power your subwoofer has, what size AMP is needed for a 1200W subwoofer, and whether your car battery can handle a subwoofer or not.
If you want to get answers to all these questions, then make sure to read this article from beginning to end. Are you ready to read the article? Let’s begin.
How many watts is a good subwoofer?
How many watts is a good subwoofer?
I’ll explain in detail how many watts are required for a subwoofer. Regarding subwoofers, voltage is important because it’s responsible for their performance.
Generally, a good subwoofer should have a power rating of at least 200 watts RMS (Root Mean Square).
However, the ideal wattage for a subwoofer depends on various factors, such as the room size, listening preferences, and the type of music you listen to.
For instance, if you have a larger room, you may require a subwoofer with a higher power rating to achieve optimal sound quality.
Similarly, if you listen to music genres that rely heavily on bass, such as hip-hop or EDM, you may need a subwoofer with a higher power rating to accurately reproduce those deep, low-frequency sounds.
It’s also worth noting that a subwoofer’s power rating isn’t the only determinant of its overall performance.
Other factors, such as the enclosure design, sensitivity, and amplifier powering the subwoofer, also play a crucial role in determining the sound quality.

How do I know how much power my subwoofer has?
Now let’s talk about how I can determine the power of my subwoofer. Knowing the power of your subwoofer is essential because it helps you determine which amplifier you need.
There are different ways to determine the power of a subwoofer, and I’ll explain them to you today.
Check the manufacturer’s specifications:
The manufacturer’s specifications usually indicate the power rating of the subwoofer. This information can be found in the user manual or the manufacturer’s website.
The power rating is often listed as RMS, the average power the subwoofer can handle continuously.
Use a multimeter:
A multimeter is a device that measures electrical properties such as voltage and resistance. To use a multimeter, set it to measure impedance (ohms) and connect the probes to the subwoofer’s terminals.
The reading on the multimeter will indicate the subwoofer’s impedance, which you can use to calculate the power rating.
Use a subwoofer tester:
A subwoofer tester is a device that measures the subwoofer’s impedance and calculates the power rating automatically.
You can connect the subwoofer tester to the subwoofer’s terminals, and it’ll provide you with the power rating.
Consult a professional:
If you need help determining the power rating of your subwoofer, you can consult a professional audio installer or technician.
They will have the necessary equipment and expertise to accurately measure the subwoofer’s power rating.
What Size Amp Do I Need for a 1200W Sub?
Let’s determine which amplifier is needed for a 120-watt subwoofer. Knowing the power rating of your subwoofer is crucial in selecting the right amplifier.
Firstly, check the power rating of your subwoofer and select an amplifier that can handle the same amount of power.
The amplifier size you need for a 1200W subwoofer depends on the subwoofer’s impedance. Impedance is the electrical resistance of the subwoofer’s voice coil, measured in ohms.
Most subwoofers have an impedance of either 2 ohms or 4 ohms, and it’s essential to match the amplifier’s impedance rating to the subwoofer’s impedance.
Assuming that your 1200W subwoofer has an impedance of 4 ohms, you’ll need an amplifier that can deliver at least 600 watts RMS (Root Mean Square) at 4 ohms.
Whenever you select an amplifier, ensure it can provide clean and stable electricity to your subwoofer without distorting or overheating it.
You should also consider the amplifier’s features, such as crossover settings, gain control, and phase adjustment, which allow you to fine-tune the sound and ensure that the subwoofer integrates well with the rest of the audio system.
Can My Car Alternator and Battery Handle a Subwoofer?
Let me guide you on whether my car battery and alternator can handle the subwoofers.
Yes, your car battery and alternator can handle the subwoofers. Still, it’s essential to understand the power requirements of both the subwoofers and the amplifier to prevent damage to the car battery.
If you start running all the subwoofers and the amplifier without understanding their power requirements, then the chances of your car battery getting damaged increase.
Subwoofers and amplifiers draw power from the car’s battery and alternator, and a high-powered subwoofer can significantly strain these components.
Selecting a subwoofer and amplifier that your car’s electrical system can power without causing damage or draining the battery is essential.
