Line Drivers & Crossovers
A line driver is an electronic amplifier circuit designed for driving a load such as a transmission line. The amplifier’s output impedance may be matched to the characteristic impedance of the transmission line.
In analog audio, a line driver is typically used to drive line-level analog signal outputs, for example to connect a stereo music player to an amplified speaker system.
When you have long wire runs to the back of a large vehicle, your signal strength may weaken before it reaches the amplifier or be clouded by noise interference. By using a line driver/crossover, you can rise the signal for better sound quality, and a noise free signal.
A standard head unit, even an after market can still produce a weak signal. Signal loss can be caused by multiple factors including weak head unit output, using mutliple devices and other factors. By placing the line driver between your head unit and amplifier, you can increase the signal as well as adjust accordingly.
