FAQs
Q: What is a MOSFET Amplifier?
A: A MOSFET amplifier is a type of stereo amplifier that works exceptionally well in car stereo applications particularly where mid and high range frequencies are important. The word MOSFET is actually an acronym that stands for Metal Oxide Semiconductor Field Effect Transistor. In plain English this just means that there is a highly efficient conductor inside of these amplifiers that helps them be reliable and produce good sound. Not long ago, MOSFET amps were only available as very high-end units, but now the majority of amplifiers are MOSFET type amps.

Q: What is the difference between a mono amplifier, a two-way amplifier, and a four-way amplifier? Which one should I buy?
A: When choosing an amplifier it is important to know what your goals are for your sound system. If you want to power a single subwoofer a mono amplifier is a good choice. A mono amplifier is a single channel amp that is ideal for low frequency situations because our ears cannot hear the difference between stereo and mono when the frequency is that low. Two-way amplifiers have two channels and are also often used to power sub-woofers however they can also be used with smaller full range speakers, but they cannot be used with both subs and mid-range speakers at the same time. A Four-way amplifier is the most versatile unit of the bunch. It features four output channels and is best suited for use in multi-speaker setups when you want to power four or more mid-range speakers or a combination of full-range speakers and subwoofers.
