Monoblock Amp FAQ
What Is a Monoblock Amplifier?
A monoblock amplifier is a single channel amp used to provide power to single-channel speaker systems. That’s why they are the typical outfit for powering subwoofer(s) – if you need to connect the speakers you should check out 5-channel or 4-channel ones.
The mono amps are designed to produce a single power indicator that is perfectly suited for the low-frequency sounds (e.g. deep bass), besides boosting specific features in the subwoofer.
Mono amps are also useful when power demands increase as they are more stable at maintaining electrical current resistance, besides having the capacity to support two subwoofers connected to a single amp. See more FAQs on mono amps.
Can you put two subs on a mono amp?
Yes, you can. Doing this will push the subs with more power at way lower resistance.
To do this, you need to know how to cut wire, use simple tools, and follow instructions.
You will need a speaker wire, a wire cutter, and a screwdriver. The first step is to cut two lengths of speaker wire and strip the insulation off of the ends of the cables by half of an inch.
Then, you connect one end of the first wire to the speaker’s output terminals located on the amplifier.
Lastly, you join the other end terminals of the subwoofer and tighten down the terminals to ensure that both wires are secure.
Can a monoblock amp run speakers?
Yes, but it has to have a full range option. So be sure to first check that. Most mono amps support 15hz to 200hz, but can not handle anything above that. Also, this way you won’t get stereo sound.
What is a Class D monoblock amplifier?
An amplifier’s class refers to its output stage. A Class D means that certain parts of the amplifier turn on and off to create the signal instead of constantly changing the volt or current. For example, Class A is the least efficient with the highest sound fidelity, while Class D has the highest efficiency with lower fidelity. The current on a Class D amplifier only flows when it’s “on” making it run smoother and more efficiently.
Monoblock Amp Vs. 2 Channel Amp?
The main difference between a mono amp and a 2-channel amp is with the number of channels, the power signals sent to the speakers. Mono amps have got a single channel (oriented in one direction), while 2-channel amps have got 2 (left and right) power channels.
With this in mind, we’ve put together detailed product reviews on the best class D monoblock amplifiers to help you overcome the confusion that may arise from the various configurations, technical details, and marketing angles.
