When it comes to choosing an amplifier for a 1000 watt sub, the most important factor is to make sure that the amp can handle the power output of the sub. Otherwise, the subwoofer will not be able to perform at its best. In general, it is recommended to choose an amplifier that can deliver twice the power of the subwoofer.

So, for a 1000 watt sub, you would need an amplifier that can deliver 2000 watts of power.

There are a few things to consider when choosing an amplifier for your subwoofer. The most important factor is the RMS (root mean square) power rating of the amp. This is the measure of the amount of power the amplifier can deliver to the subwoofer on a continuous basis.

For a 1000 watt sub, you’ll need an amplifier that can deliver at least 1000 watts RMS.
Another factor to consider is the impedance of the amp. Most subwoofers are 4 ohm, so you’ll need an amp that can handle that load.

Most amps can handle 4 ohm, but some can go as low as 2 ohm, which is even better.
Finally, you’ll need to consider the size of the amp. If you have a small car, you might not have room for a large amp.

In that case, you’ll need to choose a smaller amp. But keep in mind that the size of the amp doesn’t necessarily correlate to the power output. So a small amp might still be able to deliver enough power for your 1000 watt sub.

In general, you’ll want to choose an amplifier that can deliver at least 1000 watts RMS to your subwoofer. If you have a small car, you might need to choose a smaller amp, but make sure it can still deliver enough power for your sub.

## Subwoofer amp calculator

Are you looking to add a subwoofer to your car audio system, but not sure how to go about choosing the right amplifier? Luckily, there’s a relatively simple way to calculate the power you’ll need to drive your subwoofer, and it’s called the subwoofer amplifier calculator.
First, you’ll need to know the RMS power rating of your subwoofer.

This is the amount of power the subwoofer can handle on a continuous basis. Next, you’ll need to know the impedance of your subwoofer. This is typically listed as 4 ohms or 8 ohms.

With these two pieces of information, you can plug them into the subwoofer amplifier calculator and it will give you the recommended power output of the amplifier you’ll need. For example, if your subwoofer has an RMS power rating of 500 watts and an impedance of 4 ohms, the calculator will recommend an amplifier that can provide between 1000 and 1500 watts of power at 4 ohms.
Of course, this is just a starting point and you’ll want to take into account other factors like the efficiency of your subwoofer and the overall volume level you want to achieve.

But the subwoofer amplifier calculator is a great way to narrow down your choices and find the right amp for your needs.

## Can I use 1200w amp on 1000W sub?

Yes, you can use a 1200W amplifier on a 1000W subwoofer, but you will not be able to get the full power of the amplifier. The subwoofer will only be able to handle 1000W of power, so the amplifier will have to work harder to deliver the full 1200W of power. This will result in the amplifier running hotter and potentially overloading.

It is always best to match the amplifier to the subwoofer to avoid this type of situation.

## How many amps does a 1000W speaker use?

A 1000W speaker uses approximately 8.3 amps.

## How many watt amp do I need for subwoofer?

When it comes to choosing an amplifier for your subwoofer, the most important thing to consider is how much power you need. The wattage of an amplifier is a measure of how much power it can produce, and you’ll need to make sure that your amplifier can produce enough power to drive your subwoofer.
So, how do you know how much power you need?

The answer depends on a few factors, including the sensitivity of your subwoofer and the size of your car.
The sensitivity of a subwoofer is a measure of how much power it takes to produce a certain sound level. A subwoofer with a high sensitivity rating will require less power to produce the same sound level as a subwoofer with a low sensitivity rating.

The size of your car also plays a role in how much power you’ll need. A larger car will have more space for the subwoofer to move, which means that it will require more power to produce the same sound level as a smaller car.
Once you know the sensitivity of your subwoofer and the size of your car, you can start to look at amplifiers.

A good rule of thumb is to choose an amplifier that can produce twice as much power as your subwoofer’s sensitivity rating. So, if your subwoofer has a sensitivity rating of 80 watts, you’ll want an amplifier that can produce at least 160 watts of power.

## How do I know what size amp I need for my subs?

If you’re looking to add a subwoofer to your car audio system, you might be wondering what size amplifier you need to power it. The answer isn’t always simple, as there are a few factors to consider.
First, you’ll need to know the RMS (root mean square) power rating of your subwoofer.

This is the amount of power the sub can handle on a continuous basis. You’ll also need to know the impedance of your sub. This is usually 4 or 8 ohms.

Next, you’ll need to determine the voltage of your car’s electrical system. Most cars have a 12 volt system, but some have a 24 volt system. You can usually find this information in your car’s owner’s manual.

Now, you can calculate the size of amplifier you need using this formula:
(RMS power of subwoofer x impedance of subwoofer) / voltage of car’s electrical system = size of amplifier needed in watts
For example, let’s say you have a subwoofer with an RMS power rating of 400 watts and an impedance of 4 ohms.

You’ll need an amplifier that can output at least 100 watts per channel (2 channels required for a 4 ohm sub) at 12 volts.
Keep in mind that this is just a guide.

## Conclusion

If you’re looking to power a 1000 watt subwoofer, you’ll need an amplifier that can deliver at least 1000 watts RMS to the sub. Ideally, you’d want an amplifier that can deliver a bit more than that, so you have some headroom and the subwoofer can perform at its best. There are a few different amplifier configurations that can deliver this much power, so you’ll need to decide which one is best for your setup.
