Do you have two 800-watt subwoofers and want to know what size amplifier you’ll need? There are several elements in determining how much power your system requires.
First and foremost, the size of your vehicle’s battery is extremely crucial because it determines how long your system can operate without being plugged in.
Furthermore, the number of amps needed by each subwoofer will influence the size of the amp required.
This article will help to determine how to enjoy high-quality sound. We’ll look at the problem from both sides of the system, covering the fundamentals of power matching, the number of amps needed by each subwoofer, and impedance.
So, without further ado, let’s begin.
What Size Amplifier Do You Need For An 800-Watt Subwoofer?
A powerful amp is required when it comes to obtaining the most out of your subs. The key to getting great bass is to ensure that your amp and subwoofers are properly matched.
For instance, if one subwoofer is rated at 800 watts and the other at 600 watts, they will require more amperage than if both are rated at 800 watts.
So, you’d need an amp with at least 800 watts of power for one subwoofer. If you have two subwoofers, you’ll need an amp with at least 1600 watts.
However, most experts suggest getting an amp that can generate more watts, even more than the subwoofer’s RMS power handling ratings.
To provide the most power to your subs, they would like to see an amplifier that can handle [at least] four times their RMS.
Because you can efficiently handle the number of watts given to your sub or subs by setting your amp’s gain. Your subwoofer will be protected from being overpowered and will perform at its best.
Choose Your Subwoofers And Amplifiers
When it comes to subwoofers, you can choose between single and dual voice coils. Single voice coils (SVC) have one set of terminals, whereas dual voice coils (DVC) have two sets.
Dual voice coils have the advantage of providing more wiring options than single voice coils. Another benefit is that dual voice coils are designed for improved performance and power handling.
The amount of power required for your subwoofers is the most important feature to look for in an amplifier. Once you’ve decided how much power you need, you can go forward and choose the best amp.
There are two main amp styles available for most bass systems: mono (single-channel amp) and 2-channel amp. Always remember that single-channel (mono) amps produce the best bass sound.
They can process a single audio signal using a single channel wired to the sub for that deep bass. If you connect several subwoofers to a mono channel amplifier, they will all receive the same frequency.
Choosing The Correct Amp For The Correct Subwoofer
Consider the following four subwoofer and amplifier combinations for the best track of big bass.
1- A Single 4-Ohm Voice Coil Subwoofer
Because of its simplicity, low cost, and compatibility, a single subsystem is usually preferred. A single 4-ohm impedance is ideal for a two-channel amplifier.
By bridging the amp’s output, you’ll get a lot of power for a relatively low cost.
2- One Subwoofer With A 4-Ohm Dual Voice Coil (DVC)
DVC subs have two voice coils and can be connected in a variety of ways, allowing for greater wiring flexibility.
Another benefit of using a single DVC is improved power handling and effectiveness. As previously stated, dual voice coils are typically designed for high power handling and are extremely compact.
The mono sub amp is ideal for a single 4-ohm dual voice coil (DVC) sub. Why? Even though mono amplifiers are designed to provide more power at lower impedances, such as 2 ohms.
Maximum power output can be obtained by presenting a 2-ohm impedance through parallel wiring of voice coils.
3- Two Single Voice Coil 4-Ohm Subwoofers
For those searching for a more extensive bass, having two subs makes a lot of sense. You can move a lot of sound in the air with two subwoofers.
A mono sub amp is an ideal match for this type of setup. When connecting the two subs in parallel, you present a 2-ohm impedance to the amp.
Mono amps are ideal for such situations because they provide the most power.
4- Two Subwoofers With Dual Voice Coils At 4 Ohms Each
Two 4-ohm dual voice coil subwoofers provide a lot of wiring options. You have several options for hooking up the combination to get that bass you’ve been looking for. This combination would benefit from a two-channel amplifier.
When the subs are connected to a bridged 2-channel amp, the total impedance displayed is 4-0hms.
Is An 800-Watt Subwoofer Sufficient?
That is dependent on your implementation and requirements.
A subwoofer with 800 watts is adequate for some applications, but it is not always the best option. If you only need it on occasion, an 800-watt subwoofer will suffice.
However, if you intend to use it frequently or intensively, you should consider getting something larger and more powerful. No, they are not suitable for heavy use or when heavily used.
How Do You Connect A Two-Channel Amp To Two Subwoofers?
To connect two channels of an amplifier, you’d need a Y-adapter. This allows one channel to power both subwoofers, but it is not ideal and can be dangerous if the amplifier does not have enough wattage to power all four speakers.
Check that each amplifier has just enough channels to accommodate your setup.
For instance, if you have an amp with four channels and another with eight, you’ll need to use a Y adapter or another method of connecting two devices to ensure that each sub receives the power it requires.
How Do I Match My Amplifier To My Subwoofers?
To match your amp to your subs, consider the RMS power that the subs can handle. As an example: One subwoofer could handle 800 watts RMS, while another could handle 600 watts RMS.
In this case, we’d want an amplifier with a minimum RMS output power of 800 watts.
If not, get one with at least 600 watts because your amp shouldn’t produce more power than the subs can handle.
If you have two 800 watt subwoofers that can handle 800 watts RMS, you should use a 1600 watt amplifier to ensure that they both get the most bass impact from being driven.
Do Subwoofers With 800 Watts Have Enough Bass?
That is dependent on your requirements and application. Yes, depending on the type of music you listen to and the applications, an 800-watt subwoofer can provide plenty of basses!
Is It worth It To Invest In 800-Watt Subwoofers?
They are, in general. They can be a good option for certain applications or people who have limited space to work with.
Subwoofers with 800 watts are unquestionably worthwhile! They can definitely provide you with a great sounding system for your car, truck, boat, home theater, etc.
It really depends on the application and personal taste, but they do have a place! Yes, they are definitely worth it!
Are Two 800 Watt Subwoofers Loud?
They are, indeed, audible!
They are, in fact, louder than most people realize.
When used in conjunction with the appropriate equipment, they are sufficiently loud. At least 1600 watts RMS would be a good match.
Is It Bad To Dominate A Sub?
If an amp produces more power than is recommended for your sub, it may cause damage to the speaker. It’s best to choose an amp with just enough wattage to avoid damaging it and affecting sound quality.
How Many Channels Would I Need On My Amp To Power Two Subwoofers?
You’d need an amp with at least four channels if you’re running two subs. This will give each sub its own channel to work with while also ensuring that they both receive the same amount of power.
Can A Mono Amp Power Two Subwoofers?
Powering two subs with a mono amp is possible, but it is not recommended. A mono amp can only produce so much power, and if you have two very powerful subs, they may not receive enough power. It’s always good to choose an amp with enough channels for your setup.
How Many Watts Does A 2000 Watt Subwoofer Require?
A 2000 watt subwoofer requires at least 2000 watts RMS per sub. However, experts recommend that you give your subs the most power possible, so look for an amplifier that can handle [at least] four times their RMS.
Is A Larger Alternator Required If I Increase My Amps?
Updating from stock car audio equipment to more powerful amplifiers can increase your energy requirements, but a larger alternator isn’t always required.
Instead, keep your vehicle in good working order by having it serviced on a regular basis, and avoid driving with the engine turned off or unnecessary accessories on.
The size of the subwoofer amp you require is determined by the type and number of subwoofers you have and the electrical system in your vehicle.
For example, if you have two 800 watt subwoofers in an enclosed space, you should get at least a 1600 watt amplifier.
I hope this article has given you a good starting point for determining what size amplifier will work best with two 800 watt subwoofers.
We suggest looking for amps that are rated higher than the RMS power of each sub so that they have enough juice and continue to play loud music without disturbance!
