Abstract
An audio adapter is used with a vehicle audio system including a power amplifier, a head unit serving as a tuner, and a plurality of loud speakers mounted in a vehicle compartment. The audio adapter includes a transformer provided for every one channel between a non-genuine head unit and the power amplifier when the head unit is replaced by the non-genuine head unit. The transformer matches an output impedance with an input impedance between the non-genuine head unit and the power amplifier. The transformer adjusts an output level of the non-genuine head unit to an input level of the power amplifier.
