Just a quick question, though maybe a silly one.... my mind has gone blank so help me out here.... I have an Ampeg SVT-III Pro Head and a Mesa Boogie 2x15 Diesel Cab. The cab has two 8ohm inputs (one for each speaker) and a 4ohm input for both speakers together... My question is this: Should I run two cables from the two outputs on the back of the head into the two 8 ohm cab inputs? Or should I run one cable out of one of the outputs on the back of the head straight into the 4ohm input? Which is better / more efficient / safer / louder?
