In today’s age of high tech cars and sound systems, an amplifier can literally make or break your car’s audio system.
Most of the time, car owners are not satisfied with the stock in-car entertainment.
The amp plays a major role in producing more power to put out great sound quality.
If you’re looking for an amplifier that will power all of the component speakers of your car, then you’d need a 4-channel or multi-channel amplifier. However, if you’re looking for a gadget that will really bring out the best in your subwoofer, then you need the best mono amp for your car.
Why a Subwoofer?
For many car owners, having a subwoofer on your car is a testament to your somewhat eccentric tastes. It is one thing to drive around town listening to your favorite tunes but it’s clearly a different matter to be looking for new and better ways to enhance the optimum quality of the sound you’re listening to at all levels.
Your car’s ordinary speakers can play bass. However, standard car speakers are generally not sturdy enough to manage or handle the lower register of bass at certain desired levels.
This can lead to acoustic distortions providing you not with a pleasant listening experience but a splitting headache.
Your car’s audio system will also struggle to accommodate the increased volume and the higher bass levels.
A subwoofer takes the bass load off your standard car speakers.
It also helps protect your smaller speakers from blowing out so you won’t have to worry about replacing your entire component speaker system. Sufficient power to your subwoofer will also eliminate popping noises or even distorted acoustics.
As such, to power your subwoofer, you will need an amplifier specifically designed for it.
Why Do You Need a Mono Amp?
An amplifier is a very important component for any sound system.
Its main function is to boost the electric signals that are sent by the head unit to the speakers to provide you with an absolutely more pleasant music listening experience. To deliver power to your subwoofer, you will need a mono amp, also called monoblock or 1-channel amplifier.
Mono amps produce single power signals that are ideal for the low-frequency acoustic characteristics of subwoofers.
Because mono amps are more stable in the maintenance of resistance to electric currents especially when power demands are increased, you can actually wire two subwoofers to a single monoblock to give you an even richer acoustic experience.
What are the Advantages of a Mono Amp?
First and foremost, a mono amp is generally stable to 2 ohms. As such, it can deliver efficient power to two subwoofers, each of which can have a rating of up to 4 ohms.
If the speakers in your car are wired in parallel, it is even possible and entirely safe to connect two 4-ohm subwoofers without risking damage to your speakers.
Mono amps are compatible with speakers that have ohm ratings in multiples of 2, such as 4, 6, or 8, and so on.
Mono amps are also very cost-effective.
Since they are not as electronically sophisticated as a 4-channel or a multi-channel amp, they don’t cost as much. You can save more money by buying a less expensive mono amp to drive your subwoofer while your multi-channel amp will provide the stereo signals needed by your other speakers.
This creates a truly fantastic, cleaner, and definitely richer-sounding music.
Matching the Right Mono Amp to Your Subwoofer
In choosing the right mono amp for your car audio system, particularly your subwoofer, it is important to match the specifications of your subwoofer to the capabilities of the mono amplifier.
As a general rule, you need to look for a mono amp that can put out 75 percent to 150 percent of the total RMS rating of your subwoofer and at an impedance load that your subwoofers can be effectively wired.
For instance, if you have 2 subwoofers each with a rating of 350 watts RMS, then a mono amp that has an amp putting of 525 to 1,050 watts RMS should suffice.
Next, you’ll factor the impedance load. If you have a 2 DVC 4-ohm subwoofer, then it can be wired to form a 1-ohm or a 4-ohm system. As such, you will need a mono amp that can deliver 525 to 1,050 watts RMS at either 1-ohm or 4-ohms.
The lower values on your watts RMS will require greater values in your load impedance. For instance, you can choose 650 watts RMS at 4 ohms or 1,000 watts RMS at 1 ohm.
Now, you’re ready to choose the best mono amp for your car.
