Not just any PCS tcm-2000 but a tcm-2000 specificly prepped for the 722.6 by Sound German Automotive. Whipplem104 has spent a tremendous amount of time and effort with PCS developing their controller for the 722.6 and AFAIK is the only source for it. Whether its respect for forum rules or just modesty, he doesn't much toot his own horn about it. As a highly satisfied customer I'll take the opportunity to plug it for him. It's a great product and his support after the sale has been top notch.
