Monoblocks Amps: What You Need To Know?

Monoblock amps are considered as the power supplies for the subwoofers. These subwoofers would require more power and will not play high frequencies. These monoblocks are not full range amps however they do offer optimum power output as well as efficiency. The car amps would have a single channel having no differentiation of left or right. They could power more than a subwoofer.

In addition, there are also different kinds of monoblock amps that are available in today’s market. Having a suitable amp which would match your needs could be a challenge. Every type will offer distinct capabilities and features. The prices would vary based on the features such as power output levels, performance, and brand.

How To Hook Up Monoblock Amp?

Hooking up the amplifiers would need proper placement in relation to the speakers as well as a preamp. Follow these steps on hooking up monoblock amp:

Place every monoblock amp on either side of the preamp almost about one or two feet away from the preamp.
Connect the RCA cables right from the preamp outputs into the RCA inputs on every monoblock. There is a need to make sure that you run the left output of the preamp into the monoblock which would power the left speaker and also the right output of the preamp into the monoblock that would power the right speaker.
Now, connect the speakers into the speaker taps on every monoblock. Check the taps output rating against the speaker into the right tap. Most monoblocks would have both the 8 and 4 ohms output taps. Once the speaker is a 4-ohm load it should be connected to the 4-ohm tap.

Monoblock Amplifier: Specifications

Once shopping for the best mono amps, there are important considerations that should be kept in mind. And three of the most important specifications are the following:

Amplifier Power

The amp power output is considered as the maximum amount of power being measured in watts which the amp could offer. The number is given every channel though some amps would list the total power. There is a need to make sure matching the amp output power into the power that is needed by the speakers since too little power would lead to weak as well as distorted sound. On the other hand, too much power could blow out or destroy the speaker. 

Amplifier Channel

Amps are being categorized by the number of channels they could power. A mono amp could power a single speaker and is used in adding a subwoofer. The two-channel amps could power two speakers, four-channel amps could power four speakers and so on. The first step in choosing a capable system having four full-range speakers as well as the subwoofer is to know the number of channels needed.

Amplifier Sound Quality

The sound quality is dependent on certain factors and also the overall quality would be determined by some other equipment such as the CD player or the speakers. A low-quality amp could act as the bottleneck that prevents other components from reaching the potential. There is a need to look for an amp that has the wide frequency response as well as low deviation. The amp should also list the THD or distortion. Choose an amp which is well-constructed.

Watch this for the car audio amp power comparison:

Things To Consider Before Buying

There are also things that should be considered before buying a mono amp including the following:

There is a need to be sure that you are getting what you are paying for. In most cases, you might find that the better quality amps would advertise a more exact rating. You should first check the fuse and do the math to ensure you are getting what you pay for.

Amplifier’s Warranty. There is a need to make sure that you are to get a warranty on the amplifier. Prior to buying an amplifier, there is a need to verify that the seller in question is authorized.

Physical Size of the Amp. You should make sure that the amp will fit. You must not buy a big amp and expect it to suit under your seat.

The wiring of the amplifier is also an important consideration. There is a need for you to buy good wiring.

Amplifier feature set should also be considered. The amp must definitely do what you need it to do.

What the amp will power is also important. The amplifier should be compatible with the ohm load which you are going to be wiring it up. The amp will die if you overload it. The amp should also have crossovers which are compatible with the needed application.

And finally, you should purchase a more powerful amplifier than what you need.
