Class D amps have power supplies that are constantly switcing on and off to save power. They gain efficiency but sacrifice control n the outputs and have a alittle higher THD ratings.
The JL amps I can never ever reccomend to anyone based solely on the reason that they are probably the most inneficient power hungry amps every made. I've used them in quite a few installs at the customers requests and they always run really hot, and pull alot of amperage.
For quality of output the PRS are a "smoother, warmer amp" and are over 70% efficient so they are not power hogs.
