Amplifiers are designed both for homes and vehicles, each with differing features suitable to the required space, need and specification. There are the stereo channels and the DVD audio support systems. For cars and other vehicles with the space constraint in mind, smaller and more compact amplifiers have been designed. They come even as small as 5.4cm high and 30.6 wide and there are others which measure 10+cms high and about 43cm wide. Car amplifiers have a class A/B MOSFET Circuitry which heightens the audio quality and the epoxy circuit board that ensures longer life because it comes with semi double glass. There is the variable high and low pass crossover of 50 to 120Hz and the bass boost buttons that can be switched on and off as required.
There are various brands offered in the market and most of them come at affordable prices. There are the RCA throughput connections which can be utilised effectively by the listener. There is a three way protection circuitry which offers additional security in the car. Keeping the noise levels on the road in mind a special device has been added to help to keep the signal to noise ratio less than 100B.

The cooling fans guard against over heating. The block terminals of the amplifiers are made out of nickel plated coatings. The high gloss chrome plated finish gives a very sleek look to the device and enhances the ambience of the interior of the car. The special indications show up with cobalt blue illumination.
There are more complex amplifiers which come with more fine tuning features and tone adjustments. For better stereo effect there is a switch to balance the tone. There are five inputs found within the unit along with the tape unit. For outstanding amplification effects about 50RMS power is required.
For home needs where there is more space and the music system can be enhanced by better amplification the specifications may be slightly different. Some amplifiers measure 420mm width, 113mm height and 369mm depth. The quick response power supply circuit ensures that there is immediate response.
There are two phone pre - amplifiers and can function as AV receivers. Some offer a firm under base construction and stabilizing plate. There are aluminum side panels and metal insulators, a honey comb chassis and twin mono symmetrical construction. The equivalent serial resistance is a useful feature for high speed responses. Some also offer continuous power output up to 20 to 20,0000Hz at four Ohms and eight Ohms. The sound retriever analogue and the large speaker terminal for that extra amplification effect are quite out of ordinary. There is also the System remote control unit and LCD dimmer. Many of these are power saving machines because they run on low power.
