Amplifiers or amps are used t increase the strength of the audio signal so it can power the speakers properly. Car amplifiers are designed to take up lesser space, a lot of them fit under the passenger seat. Amplifiers are expensive devices, with slight variation in prices depending on the brand and specific model one chooses to buy.
An amplifier increases the signal strength so it can drive speakers with more power. The only difference between a car amplifier and a regular one is that the ones for cars are designed to be more compact and handle heat better, given they are in an enclosed space. Especially since a lot of them are placed under the driver or passenger seat. This being one of the reasons that at times the whole body is designed like a heat-sink and made from aluminium, making for the most efficient possible cooling.
Importance of amplifier
The original signal from most devices is too minimal to power large speakers and create a full-bodied sound. Once such a signal passes through an amplifier it is strong enough to drive speakers enough to create the wanted levels of sound. This gives them that kick one needs to really feel their music.
Car amplifiers are available in various designs, depending on the brand and the specific line by them. Amplifiers have multiple inputs so one can connect various devices, some also work in tie with a media console. This variation depends on the car amplifier you choose. The power ratings are different too, and one can choose the right one based on how many speakers and subwoofers they want to have powered.
Available at many different prices given many brands produce car amplifiers. The prices are from a higher point on the price spectrum. Known brands include Sony, Alpine, Rockford, Kenwood, Pioneer, JBL, Lanzar and many more.
