I'm currently on the lookout for my first head/cab setup, and like many of us, am a little confused when it comes to ohms and compatibility. (And yes, I have already read the sticky at the top of this section.) I ran across a used Genz Benz 4 x 10 cabinet, but it's an 8 ohm cab. Which means any amp I use will be running at the lower wattage 8 ohm setting. Based on what I've learned so far, I would want a 4 ohm cab to get the maximum wattage output from my amp, as most amps list their max wattage for 4 ohms, right? Or is there away to change the cab from 8 to 4 ohms? Thanks in advance for any helpful advice!
