Class D Amplifiers are ideal for Car Audio

When efficiency matters, get a Class D Amplifier.

When working with car audio, there are so many factors to consider before approaching amp classes like Class D Amplifiers.

Space and efficiency are top concerns next to sound quality and sound pressure levels because of how they affect Sound Quality and Sound Pressure Levels.

For maximum efficiency in the substage, most opt for D Class.

D Class Amplifiers differ from Class A/B Amplifiers in several ways. They are made for greater efficiency, have a smaller footprint, and provide greater heat dispersion.

They are switching amplifiers

In switching amps like Class D, the amplifying circuit, or MOSFET, rapidly switches on and off during operastion.

MOSFETs have the lowest resistance when they are fully on and therefore operate with great efficacy.

Compared to Class A and Class B amps, Class D’s low energetic losses allow for the use of a smaller physical heat sink, permitting for smaller and lighter amps. This translates to more efficient performance, greater enjoyment of your music, and less hassle to play that music.

Class D boasts between 85-95% efficiency

Class A/B Amplifiers lose upwards of 35% of their energy as a result of biasing and operation.

There is a massive amount of efficiency gained by using a Class D Monoblock Amplifier like the Q1-2200.2 Monoblock Amplifier over Class A/B Amplifiers.

When size, efficiency, and operating temperatures matter, opt for Class D Amplifiers. SoundQubed offers a stellar selection of Class D Monoblock Amps with an affordable S Series line for daily drivers and a Q Series line for competitive bassheads.
