    I have a 6x10 AIMs bass cab that is rated 5.3 ohms. (If you have more information and think this is wrong please feel free to say so). I've even using an acoustic B2ooH head that is 4ohms. I wanted to know if this is safe or very bad? And what new head would you recommend me to get that would suit the cab best?

    A higher impedance of the cab is fine with a solid state amplifier. It will not give you the maximum output power but it is not dangerous to either the amp or the cabinet

    With a 5.3 ohm cab you'll get very slightly less power from the amp than you would with a 4 ohm. Not even noticeable.

    How did you determine 5.3 Ohms? With a DVM? How much resistance in the test leads?

    He said it's rated 5.3 ohms so presumably the manufacturer determined it.

    You'll be fine. Any solid state head rated for 4 ohms or lower will work fine with that cab. If you get a tube head, use the 8-ohm output. I'd recommend the Gallien Krueger MB Fusion 800 for you.

    Many six-driver cabs are rated at 5.3 ohms.

    Reciprocal of sum of reciprocals of parallel loads. Sum of series loads.

    3 parallel sets of 2 series 8 ohm drivers.

    1/(3/(8 + 8))= 5.33333.
