The factory that builds our unit and the ATI unit also manufacturers under contract several other brands of power amplifiers. Some of these models are made for very famous large companies in conventional distribution. Other models are for the rapidly growing custom installation area. Suffice it to say, that the Outlaw power amps are only a small portion of what comes out of this factory, but the design is our own. To anticipate your next question, our circuitry is entirely different than that of the ATI designs.
