Has anybody rewired a 4-10 8 ohm cab to run as 2 2-10s at 4 ohms? I am considering a 4-10 setup so that I can compete with the drummer with 1 cab....1-15 just falls a little short. The head is a Groovetubes preamp with an old QSC 1400 power amp rated at 200@8ohm/300@4 ohm per side. Considering used pro line cab (eg SWR/Eden) which could stand for 600+ watts. If I run the cab @ 8ohm I would be limited to 400 watts with the power amp in bridged mono operation. Would I run into maximum displacement power limits? Budget wont allow for new amp at this point.... Tell me if I am crazy.
