Go to the JBL professional site and look up "suppoprt", "Downloads", "tunings", and "SRX700 series" in that order...in the zip file locate the last file " SRX700 tunungs for dbx driverack PA vev..." open it and scroll down to the SRX725 W subs, there are the tunings.. you could also download the tunings into one of the amps and then just manually configure the others using those settings they provide for a single amp bi-amp...
Good luck, keep us informed.. I'm off to weddingsville
