The JBL SRX715 Bi-Amp specs state that the horn can handle 75w Continuous @ 8ohms but it will handle 150w Program and 300w Peak. I don't have an amplifier that only produces this wattage. The lowest I have is an old Fender SPL6000 which will send 150w @
8ohms. And just my luck this old amp doesn't have Speakon connectors. So, I will need to use a Peavey GPS 2600 which produces
650w @ 8ohms. Well beyond the specs. Will this hurt the horn driver? I am going to use a new dbx Driverack PA+ and of course my Peavey GPS series amplifiers are not listed in there. The system will have the JBL SRX718S subs too and I will run the mains and subs with the Peavey GPS3500 amps (775w @ 8ohms). Any suggestions or comments would be greatly appreciated. Thank you.

Having too big of an amp isn't necessarily a problem, so long as the operator doesn't keep turning things up. Any amp is only going to put out as much power as you tell it to by how loud you run things. Set your system up so the levels are balanced and you should be fine.
As an extra safety precaution you might lower the levels of any input sensitivity controls (volume knobs) on the amp itself, but you don't have to.
