this is my first post and cab building experience. Im building an 8x10. I have a Ampeg SVT3-PRO head with an output of 450 watss at 4 ohms and 275 at 8 ohms. It has two jack outputs(wired in parallel). If i wired the cab as 2 4x10s down to 8 ohms each, could i run both outputs at 275 watts? Would this relieve the amplifier a little? Hope this makes sense its not my area of expertise....yet!
