Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
Installing sound damping or deadening materials, also referred to as sound deadener or "dampening" (one of the most misspelled words in car audio), in various areas of your vehicle is one of the best ways to enhance your car's audio system while adding the proper insulation. Vibration absorbing materials from popular brands such as Dynamat, Hushmat, NVX, Cache and Stinger allow you to significantly decrease road noise and vibrations, soundproofing your car for maximum audio quality.
