The only way to get really great bass is with a subwoofer, but the choice to feature a subwoofer in your audio setup is merely the primary step on a long journey.
The energy you would like to power your hungry submarine comes from somewhere. The question is are you able to scream with the already existing Ampy, or does one actually need to feature a dedicated subwoofer amp at an equivalent time you add your subwoofer?
The answer is complex and really depends on factors like what proportion of money you would like to spend and the way qualified you’re on the sound of the finished product.
Certainly, there are ways to form an influence amplifier work with a subwoofer, but the simplest result always comes from a subwoofer and amp combination that desires to realize beautiful harmony.
Importance of impedance
An important thing to consider here is impedance, which basically means electric resistance (measured in ohms). the various subwoofers on offer will allow you to settle on between 2 or 4-ohm ratings, and this suggests that you simply will take impedance when trying to attach subwoofers and amplifiers once you want to put in one.
There are not any quite two subwoofers (basically a pair of subwoofers with an impedance of 4 ohms means you’ll need an amplifier of the nominal impedance of 8 ohms); However, if you’re trying to line up a dual voice coil (DVC), which is for quite one input connection, things can get tons more complicated.
Power handling is one of the key features of a speaker or receiver, which is the amount of power required from the receiver/amplifier to operate the speaker and reproduce the sound while minimizing audio distortion. It is measured in Watts and indicated by w. Other common terms for this include RMS, Vertex, Program, and Continue.
As a general practice, most manufacturers refer to force and impedance. However, if a manufacturer has listed maximum power or RMS (average output power), it is worth checking again. It is also important to note that some home theater manufacturers refer to recommended power amplification in terms of the main speaker specifications.
For example, if you have 6 speakers with a power handling range between 100 and 150 W, then you will need a receiver or amplifier with a power rating of at least 100 W (RMS) up to 150 W. It is worth noting that if your amplifier has less than 100 watts, you may experience distortion and speaker damage.
Ideally, an amplifier should provide 10% more power than speakers. This well compensates for lightning peaks due to dynamic range fluctuations. Beware of sudden hits with action sequences in a film, such as an orchestra or an explosion with drums or a musical part, as this can cause the tweeter to fly.
The sensitivity space can be found on the speaker’s datasheet. Typical sensitivity for public address speakers is 95 to 110 dB-SPL / WT / m. larger speakers typically have higher sensitivity than smaller speakers, and higher frequency drivers have higher sensitivity than low-frequency drivers.
Importance of the pairing
To make sure your car stereo has great bass, you need to find an amperage that matches your subwoofer. In other words, the amplifier’s capabilities must match the subwoofer specifications to work together.
For the best sound quality, make sure the RMS watts of the amplifier and subwoofer match.
Who Needs a Subwoofer Amplifier?
The short answer is that everyone who wants a subwoofer in their car needs a subwoofer amplifier too. For example, if you need a separate amplifier for your subwoofer, it depends on the hardware you already have and the car audio system you have built.
Since everyone wants something different in their car audio system, there really are no wrong answers, but this is probably the best answer for your particular situation.
Select your subwoofer and amplifiers
When selecting a subwoofer, you can choose between a single voice coil and two voice coils. Single voice coils have one set of terminals, while dual voice coils have two sets of terminals.
The advantage of the dual voice coil is that it offers you more wiring options than the single voice coil. Another advantage is that the dual voice coil is designed to improve performance and handling power.
When it comes to the top, the most important thing is the amount of power required for your submarine. Once you determine the amount of power required, you can go ahead and select the best amplifier. There are two main amp styles available for most bass systems; Mono and 2-channel amplifier.
Always keep in mind that single-channel amplifiers are best for producing excellent bass sound. They are capable of processing a single audio signal using only one channel connected to the subwoofer to achieve that excellent bass. You can connect multiple subsystems to a mono channel amplifier and each subwoofer will receive the same frequency.

Finding the right subwoofer for your amp
Find the power range of the amplifier
The RMS watt rating of the subwoofer must match the amplifier’s electrical range for optimum sound. Find the power of the amplifier at 4 ohms, 2 ohms, and 1 ohm in Watts RMS.
Choose the RMS power rating you want to achieve. Your subtotal impedance will be the load impedance (ohm) of that rating.
Decide on the membership number
Take the RMS power rating you selected in the previous step and divide it by the number you want on your car stereo. The result is the target RMS rating you will need for each sub.
Divide the target RMS rating by 1.5 to get the minimum RMS rating that will work for each sub, and then divide the target number by 0.75 to get the maximum RMS rating.
Time to matching
Finally, you are ready to pair the right subwoofers with the right amplifier for your new car audio system. Therefore, to get the best possible bass sound, you should consider the following when it comes to matching:
A single subsystem
It is generally preferred by professional installers for reasons of simplicity, compatibility, and affordability; basically, a bogey standard 4-ohm single sub-channel amplifier is going to be a great option because the amplifier output needs to be brimmed properly and cheaply at that point.
Such a subwoofer should give you plenty of wiring flexibility, meaning that in addition to a wide variety of sound options, great operating power, and good performance (which is why the 4-ohm DVC subwoofer is a good choice for the mono sub is. Amp). Phosphor 😉 The latter is intentionally designed to provide high power at low impedance.

Two 4-ohm single voice coil subwoofers
Why opt for two subs? Easy; to get more bass, you are going to choose the mono sub-amperage for your sound system and the best match for them, as they will both sub-wire in a parallel connection, thus providing a two-ohm amplifier impedance value. , One position is ideal for a mono amplifier to obtain the maximum possible power
Two 4-ohm DVC subwoofers
Going for this option has to do with the flexibility of the strings, as it provides a number of separations to add to the combination, resulting in terrible bass production; for intelligence, a two-channel amplifier would be ideal in this scenario.
A more powerful amplifier makes your speakers louder
A more powerful amplifier will give your audio system more headroom and improve the sound quality of audio. More power will allow you to turn on the music before amplifier distortions. However, if the speakers cannot handle the extra power, they will distort. With more powerful amplifiers and speakers that handle the power, your speakers will definitely make a louder sound.
Manufacturers recommend wiring specifications for their products in terms of wire gauge (thickness) and material. Using wiring that is too thin or is made of inferior material, the power can redeem the amplifier, which you need to perform better, thus limiting the performance of the amplifier.
When 2 channels form a channel jointly this process cuts the ohm load in half, thus providing more power to the speaker than the amplifier. This practice is commonly used to feed subwoofers in multichannel amplifiers. For example, if you have a 4-channel amplifier, channels 1 and 2 are used to provide power to the left and right speakers, channels 3 and 4 have subwoofer power. Note: Not all amplifiers can be bridged.
Although it’s easy to seek out an entire set of the simplest subwoofers and amps, most people like better to buy them separately. For best results for your vehicle’s audio system, the mixture of a subwoofer in an amplifier can only be achieved by combining the first components.
When purchasing a subwoofer, always confine mind its frequency response and sensitivity. For crisp, clear sound, confirm the amplifier and subwoofer match impedance and power handling capabilities in the maximum amount possible. Additionally, an in-depth combination of the amplifier’s handling capabilities and secondary power ensures the safe operation of your equipment by reducing the risks of overheating.
