Efficiency of Class A/B Car Audio Amplifier and MOSFET Technology

Amplifiers with class A/B topology use two types of transistors. The good qualities of each are put together resulting in the best compromise of the two classes.

An “A” amplifier has a massive volume of current passing through its output transistors without an audio signal while a class “B” amplifier has no current flowing through its output transistors with no audio signal. Having the two classes of amplifier combined, it gets rid of almost all crossover alteration.

As a result of the combination, Class A/B is more efficient compared to class “An” amplifiers without the probable distortion of a class “B”.

Metal oxide semiconductor field effect transistors (MOSFET) is used to switch the amplification signals in the device. It influences the flow of electrical current thus it controls or prevents movement of power resulting to an efficient amplifier. Because of MOSFET technology, you will still get high-efficiency output even if you rapidly switch from full to non-conduction.

Variable Crossover Combined With Switchable Bass Boost

The crossover effect is a process produced by subwoofers wherein it reproduces a sound based low range frequency. This occurs because most of the audio system does not have the capability to cover the entire spectrum sufficiently thus sound distortion is common.

For the Boss Audio R1100M, it offers variable crossover which allows the user to set the frequency resulting to defined sound specification on the subwoofer.

Adding to the quality of this amplifier is the switchable bass boost which enables you to control how much bass output you want from your subwoofer.

With the variable crossover and switchable bass boost, you can customize the sound according to your preference.

Boss Audio R1100M Reviews

Boss Audio R1100M got an editor rating of 8/10 because of its excellent performance at a very reasonable price. It’s sleek and compact design allows easy installation. One customer commented that he installed his amplifier on his own without any issues. He said that the controls do exactly what they’re supposed to do so you won’t have a hard time figuring it out. It is a great choice for a novice who is not into technical stuff.

In addition, the buyer said that the system sounds remarkable and even after several months from installation, this amplifiers durability, and quality is still the same. He initially thought that he would have to replace it after several months of usage because of its price, but it definitely exceeded his expectations. He highly recommends this for people who want to enhance their audio system who are under a tight budget.

Things to Improve

Boss Audio R1100M is by far one of the top performing amplifiers, however; it also has its minor issues. One issue that a few users point out is that the remote subwoofer control does not work. This only happens when the amplifier is switched to a full range which rarely occurs. To get the best out of the remote control, turn the amp to low pass mode and avoid switching it to full blast and it should work perfectly.

Despite some issues with its remote, the Boss Audio R1100M still tops the list because it performs well. It does not only produce superb quality sound at a reasonable price. It is also very durable and will last for a long time.


For quality and affordability, Boss Audio R1100M amplifier is something to consider. With its minimalist design, this Monoblock amplifier produces a power of 250 Watt RMS output and it has a maximum amplification of 1100 watts for a powerful sound. It’s built-in variable crossover and switchable bass boost drives the subwoofers so you get an impressive sound to noise ratio of 102 dB. It is ideal but not limited to your car stereo.

With this amplifier, you will get more than what you pay for.
