Jerry, I have 2 JBL MRX518S subs (only 1 - 18" driver per cab) and I power them with one Crown CTs 2000 delivering 1000 watts to each sub at 8 ohms. This setup provides more than adequate power for almost any application. I also do all my processing with a DriveRack PA and not let the amp do it.However, since the power handling of the MRX528S is 1000W / 2000W / 2000W you should put at least 1000W into each sub. Perhaps even 2000W to each sub. Its better to have a more powerful amp than speaker because you're more likely to blow a speaker with distorted signal from the amp than a signal that is too high. You should perhaps ask JBL their opinion about which Crown amp to use. Sweetwater engineers are also very helpful!
