Amplifiers Products
Basically a mobile Audio amplifier, a car 'amp' is a term used to refer to a dedicated electronic amplifier separated from the other components of the system. Though most head units have an amplifier, some do not, or lack desired features. External amplification is available and most often used when existing amplification is insufficient. This is usually the case when powering a subwoofer, where desired wattage may be several multiples more compared to other cabin speakers.
Though less common, oem external amplification can be found in 'premium' audio packages, or in luxury cars. More common is aftermarket amplification installed later to satisfy the expansion of an existing system in some way.
During operation, it is common for a vehicle's charging system fluctuate, so a regulated amplifier will maintain its power output regardless of voltage fluctuation. Amplifiers rated at 100 watts @14.4 volts can not be regarded equal as to an amplifier that can maintain 100 watts @ 12 volts. Oustide of certain standards, it is not uncommon for manufacturers to list a 14.4 rating & not post a 12 volt value.
