I get horrifically confused about ohms and such. I currently own an SWR Workingman's 4004 head with a matching 4x10t cabinet and I am that close to buying an ampeg SVT15e to put underneath it all. I want to gradually upgrade my entire rig to all ampeg so this is phase 1. I just want to figure out if this current rig system will work and not damage anything. would be running both cabs (both are 8 ohms) out of the 4004 head. the power output specs for the 4004 head are: 400 Watts RMS @ 4 Ohms 260 Watts RMS @ 8 Ohms (Minimum Impedance 4 Ohms) will it work?
