An amplifier is the heart of your car stereo system designed to take a low level signal from your head unit and then boost it to drive speakers. Depending on the type of your system, the amplifier may range in power from dozens of watts to thousands of watts per channel as well as vary in quantity of outputs. If you have a basic factory sound system, most probably it utilizes a built-in amplifier with just a couple of outputs, while the majority of high-class factory-installed stereo systems come equipped with a powerful external amplifier which supports up to 8 channels.

    In fact, an amplifier is usually out of sight and out of mind, which is why we remember about it only when it is already malfunctioning. However, this component is crucial for your audio system and makes the difference between good and great sound, so it is rather important to fix it in time. If you’re looking for a quality replacement amp, we offer you the widest collection of top-notch factory replacement amplifiers for your system. Designed with maximum precision and quality in mind, they will provide years of reliable service and excellent performance.

    Since we listen to most tunes in stereo, nine of ten factory amplifiers have at least two channels. In practice, the most common factory amplifier supports four speakers which are usually located pairwise in the front and rear side of the vehicle's interior creating a surround effect. Some of them may also have a separate output for a loudspeaker to provide the most realistic audio experience possible. That is why, while choosing a replacement amplifier, don’t forget to count the number of speakers you have to pick out the right device for your vehicle's entertainment system. On our website you will find a broad variety of replacement amplifiers, so you will undoubtedly choose the perfect one that meet your specifications.

    The power rating of your factory amplifier is one of the main characteristics that you should check prior to purchasing a replacement amplifier. It describes the ability of your device to amplify an audio signal it gets from the head unit or stereo receiver. The standard for obtaining amplifier wattage ratings is RMS that stands for "Root Mean Square" and measures the magnitude of the output signal. Evaluated in watts, it determines the maximum sound power that your amplifier is able to provide at its peak performance. In brief, it says how loudly your stereo system can sound when you turn the volume regulator to the maximum. The majority of factory amplifiers provide a significantly high RMS rating for powerful and clear sound.
