Single-channel power amplifiers for a car are sometimes called subwoofer monoblocks. They are designed specifically for connecting multiple subwoofers.
Monoblocks have some distinctive features related to their scope and are widely popular.
Features of single-channel amplifiers
Many motorists want to buy a monoblock, because it has the following features and advantages.
Firstly, these are monophonic amplifiers. When you feed them a stereo/mono signal from the radio that is collected in the amplifier, the output is a mono signal through the subwoofer
- Secondly, single-channel amplifiers have a fairly high power. At 4 ohm load, the power per channel is from 150 W.
- Thirdly, in such subwoofer amplifiers, there is a high-pass filter that cuts off all frequencies that are higher than the filter settings frequency. And this is a prerequisite for connecting a subwoofer.
- Fourthly, in monoblocksoften there is a so-called subsonic filter, which cuts the ultra-low frequencies from the musical signal. This is a pretty important thing, because hitting the subwoofer with ultra-low frequencies can damage it.
Famous Manufacturers
Alpine is well known in many countries. Models of amplifiers let out by it differ in the compact sizes and high-quality sounding. Alpine's digital broadband all-in-ones are consistently in high demand.
The Audison brand presents monoblocks for Hi-End class cars, which are distinguished by detailed sound reproduction and high power. The manufacturer attaches a certificate of conformity to the device, which confirms the characteristics of all the specified parameters.
Monoblocks of the Korean company Kicx are represented by many models with different capabilities, price and functionality. This brand is a leader in the production of car amplifiers, speakers, subwoofers, cables and accessories.
Choose a monoblock
Single-channel power amplifiers have many parameters and characteristics that must be taken into account when choosing. The most important ones are:
- amp class;
- subwoofer power;
- max amp load;
- minimum system resistance.
Most of the all-in-ones on the market are class D. They have higher power and are smaller in size than A/B devices, besidesthey heat up much less. But at the same time, the sound from single-channel class D amplifiers is slightly inferior in sound quality to analogs A / B. Although if the signal is sent to the subwoofer, then the difference in quality cannot be felt.
A/B all-in-ones are cheaper, which is why they are a budget option.
Next, we offer an overview of single-channel power amplifiers of the most popular models with their technical characteristics.
Kicx AD 1.400
With the highest efficiency, the all-digital circuitry of this monoblock allows you to get up to 360 watts of power from miniature amplifiers for a four-channel amplifier and 650 watts for a subwoofer model. This single-channel subwoofer amplifier "Kix" is part of a series of economical, high-bandwidth and ultra-compact class D devices.
Specifications:

Alpine PDR-M65
The new single-channel PDR series amplifiers feature an all-new design that delivers superior sound quality, high performance and excellent reliability. This digital mono amplifier has dual internal error correction technology. Now the input signal is first analyzed, then compared and corrected twice.
This monoblockuses a separate circuit for multi-stage power controls. It constantly monitors critical component temperatures throughout the amplifier and reduces output power as needed.
This amp has an amazingly clear and uncolored sound.
- Max power is 1300W.
- Rated power - 450 W.
- Frequency range - 8 to 400 Hz.
- Amp class – D;
- Dimensions - 229 x 165 x 51 cm.
