DBX DriveRack PA first edition

Hello, I'm wanting to set up my D R in a tri amp mode using EV horns , JBL 15" X 2 for the mids , and JBL 18 " for the subs . I tried setting # 8 and performed a custom set up crossovers etc. But when I tried to power up under this setting both cabinets JBL 's sounded as if they were playing at full range , so I stopped there ! I would appreciate any serious help to set this up , Thanks in advance.
