Right now i have a 2x10 8ohm 200watt cab. Might be able to trade for a 4x10 8ohm 200watt cab. Would it be any louder being the same amount of power? would the 2 extra speakers make a big difference with no extra power?I was thinking of getting a 4ohm cab so my amp will push 350 watts to it. Most it would see would be playing with a band/small gigs.
