Car audio specialists also concentrate on the signal to noise ratio. By and large, they agree that the higher the better, as it will enable a listener to hear mid-bass and range, as well as the higher rangers. For bass lovers, there are a number of amps on the market, which are purely dedicated to bass. However, they often have issues with signal and noise issues.
Efficiency is not only integral to saving power, but if your amplifier is not efficient it will not have the correct continuous power. Manufacturers sometimes claim an efficiency rate that is not quite correct due to using a smaller sized fuse than is needed. Check the maths out with this one. A standard amplifier should be at least 50% efficient and any less is generally not worth your money. To find out if your amp is efficient, divide the total power by the battery voltage - the number you get out will be the size of fuse you need in your amp. Any smaller sized fuse will lower your amps efficiency rate.
A guitar amp is basically an electronic amplifier which is designed to make your electric or acoustic guitar to be heard through loud speakers.

When you say preamplifier, it is the one responsible in amplifying the guitar's signal to a certain level that then drives the power stage.
