Today I got teo GK backline 115 BPX cabs. They are 8 ohms at 200 watts. Is that peak? My B2R/SVT 350 is 200@ 8 ohms, and 350 @ 4 ohms. When I am running it like a half stack would I be ok as long as I didn't push my amp to the max? Also when I run both cabs I am running a speaker cable to each each cab. Is that pushing 350 watts to each cab? Or is it about 175 to each cab? Trying to make sure its ok to run this head with these cabs so I don't blow any speakers.
