Legacy amps are some of the most advanced car amplification products
available. These quality audio products are designed and engineered to afford
you years of uncompromised musical service. Legacy has utilized the latest
electronic technologies in order to deliver a superb listening experience.
This innovative system has been designed utilizing a 12 V DC Negative Ground
power supply. The LEGACY Red SERIES 2 amps incorporate two to eight
MOSFETS in the different models.
This design produces enough available voltage to supply the main amplifier
sections, and still have a huge amount of reserve voltage for peak “high
demand” situations.
The Legacy line has been designed to ensure adequate headroom for even
the most demanding peaks and dynamic ranges found on today’s CD’s and
recordings. Used properly, these amplifiers will provide you with years of
listening pleasure.
