Yesterday I bought a Aguilar GS112 cab, I wanted something portable. I also bought a Eden Nemesis NA320 head. I am new to bass, I did have a Crate 160 bass combo years ago, but this is the first time I got head and cabinet. I didn't do any research, I just went out yesterday afternoon and bought the stuff since i just joined a band as bass player and need gear. manual says the head produces 350 watts into a 4 ohm cab, or 200 watts into 8 ohm cab. 4 ohms is louder than 8 ohms? So if I plugged into 4 ohm cabinet it would be louder? My cabinet is 8 ohms so if I plugged into TWO cabinets, it would be twice as loud? better to get a louder amp, or another cabinet? I've always played electric guitar, in combos, i have no idea what I'm doing with cabs and heads.
