Do you have a 1000-watt sub and need to know how big of an amplifier you’ll need?
For a 1000 watt sub, It would be best if you looked for an amplifier that can output at least 1000 watts RMS per subwoofer in order to make your subs work at their best.
This guide will help you to understand how to enjoy high-quality sound. We’ll cover the fundamentals of power matching, the number of amps needed by each subwoofer, and impedance from both sides of the system.
So without any further ado, let’s begin!
What Size Amp Should You Get For A 1000 Watt Subwoofer?
The amount of power your system requires is determined by a number of factors. You’ll need a power amplifier capable of delivering at least 1000 watts.
And if you have two subwoofers, you’ll need an amp with a power rating of at least 2000 watts.
It would be best if you looked for an amplifier that can output at least 1000 watts RMS per subwoofer in order to make your subs work at their best.
Let’s say you have two subwoofers with a maximum power rating of 1000w RMS x2 = 2000w. We’ll need an amp that can deliver at least 2000 watts RMS to make them work efficiently.
However, most professionals suggest having an amp that can generate more watts, even more than the subwoofer’s RMS power handling ratings.
Because by setting the gain of your amp, you can easily manage the number of watts provided to your sub or subs, and preventing your subwoofer from becoming overpowered and performing at its best.
So in that case, you’ll need an amplifier that’s [at least] four times the RMS of your subs.
Remember that these are just guidelines, and your system may need more or less power, so it’s recommended to seek advice from a professional before purchasing.

Factors To Consider When Getting An Amp For Your Subs
First and foremost, the battery size of your vehicle is very important because it determines how long your system can operate without being plugged in.
Second, the number of amps needed by each subwoofer will influence the size of the amplifier you require.
If one subwoofer is rated at 1000 watts while the other is rated at 800 watts, they will need more amperage than if they both were rated at 1000 watts.
Many factors go into defining an amplifier’s power rating, and not all amplifiers with high ratings can handle 1000 watt subs.
This is because some amplifiers have a maximum wattage output, whereas others generate higher wattages but only at specific frequencies.
Look down below for a general rule of thumb for calculating power requirements based on RMS rating.
The Amount Of Power Required By A Sub From An Amp
Subwoofers typically have two power handling ratings. The RMS rating of a subwoofer is a measure of how much power it can handle on a regular basis.
On the other hand, the peak wattage indicates the maximum amount of power that the woofer can endure without being damaged.
When selecting an amplifier for your subwoofer, it is important to choose an amp that can provide the appropriate amount of power to the sub without exceeding its RMS rating.
If you choose an amplifier that is too powerful for your subwoofer, you risk damaging the voice coils, which can cause distortion, reduced output, and even complete failure. On the other hand, if you choose an amplifier that is not powerful enough for your subwoofer, you may not be able to achieve the desired volume or low-frequency response, and the amplifier may even overheat or fail due to being pushed beyond its limits.
Always match the RMS watts of the amp for the best sound quality. Most power amplifiers on the market today display RMS watt ranges, indicating the maximum and minimum power ranges that the amp can generate.
Once you’ve calculated the amp’s wattage range, make sure the RMS watt power of the subwoofer is between 75 and 150 percent.
Measure your subwoofer’s “watts RMS” rating, then multiply the number of subwoofers by each one’s RMS rating. This gives you the RMS rating for all of the subs as a whole.
For example, if we have two subwoofers, each rated at 1000 watts RMS, multiplying 2 by 1000 gives us 2000 watts, which is the power required for two subwoofers.
This ensures that the amp you select can deliver 75-150 percent of your sub’s total RMS rating.
Impedance is another important aspect when matching subwoofers to amplifiers. The term “impedance” describes the measurement of electrical resistance.
The majority of subwoofers on the market today allow you to choose between a 2 ohms or a 4 ohms rating. Matching impedance is a simple concept, particularly when only one or two subs are being installed.
Things get a little more complex when connecting multiple subwoofers or dual-voice coil (DVC) subwoofers with two input and input connections.
For example, Two 4-ohm subwoofers require an amp with an 8-ohm impedance rating.
When connecting multiple subwoofers, make sure they have the same impedance and coil. There will be no equal separation of power between them if they do not meet this requirement. As a result, some subs are underpowered, while others are overpowered.
Take into account connecting each subwoofer to its own amplifier if you plan to use different types of subs in your car’s audio system.
How Do I Match My Amp To My Subs?
If you want to match your amp to your subs, you must first determine how much RMS power the subs can handle.
For instance, one subwoofer may be capable of handling 1000 watts RMS while another is capable of handling 800 watts RMS.
In this case, we’ll need an amplifier with a minimum RMS output power of 1000 watts.
If not, get one with at least 800 watts because it’s preferable for your amp, if it doesn’t put out more power than the subs can handle.
If you have two 1000 watt subwoofers that can each handle 1000 watts RMS, you’ll need a 2000 watt amplifier to ensure that they both get the most bass impact from being driven.
Are 1000 Watt Subs Worth It?
They are, in general. For some applications, they may be a viable option or for people who have a limited amount of working space.
Subs with 1000 watts of power are well worth the investment! They can provide you with a great sounding system for your car, truck, boat, or other vehicles.
They have their place, and the vast majority of people will be content with them. Subwoofers with 1000 watts of power are fairly common and can sound fantastic in the right setup.
It all depends on the application and personal preference, but they do have a place! Yes, they are well worth the money!
What If My Amp is Too Powerful For My Sub?
If your amp is producing more power than is recommended for your sub, the sub may be damaged. It’s best to choose an amp with just enough wattage to avoid damaging it and compromising sound quality.
Do 1000 Watt Subs Have Enough Bass?
That is dependent on your requirements and intended use. Yes, a 1000 watt sub can provide plenty of bass depending on what form of music you listen to and the applications.
How Many Volts Does My Speaker Require?
If you’re not certain how much voltage your sub needs, it’s best to consult with the supplier before making a purchase. Different subs demand different voltages, so you don’t want to end up with an amp that either doesn’t have enough power or is too powerful, causing damage to your equipment.
Is Overpowering A Sub Wrong?
If an amp generates more power than is recommended for your sub, the subwoofer may be damaged. It’s best to choose an amp with just enough wattage to avoid damaging it and compromising sound quality.
Can I Use A Battery To Power My Amps?
It is possible to power your amps with a battery, but this is not recommended because it is potentially dangerous. You take the danger of an electrical fire if something goes wrong with the battery or wiring. It’s best to use a high-quality power source built specifically for amplifiers.
Can I Wire Two Amps Together?
You could, but it’s not a good idea because both amps might not get enough power, affecting the sound quality. Alternatively, before making any purchase decision or wiring, you should seek advice from an expert.
The size of the subwoofer amp you need is determined by the type and number of subwoofers you have and the electrical system in your vehicle.
For example, if you have 2 1000 watt subs in an enclosed space, it would be best to get a 2000 watt amplifier.
I hope that this article has provided you with a good starting point for determining what size amplifier will work best with 1000 watt subs.
We recommend looking for amps with a higher RMS power rating than the RMS power of each subwoofer, so they can both get enough power and keep playing loud music without distortion.
