4 ohm or 8 ohm???

[Broncrider32]

I'm currently running a Mark III Centurian which is 130 watts at 4 ohms. I am running one 15" 8 ohm cabinet. I was wondering if I was getting the most power out of my head with this 8 ohm cab. Also I'm thinking about adding a 210 cab but doesn't it matter if it is 4 or 8 ohm. I guess I really don't know really what the ohms stand for or what the difference is please help me out. THANKS>>>

For your needs, add another 8 ohms cabinet to get the most output of your amp, which will be then at 4 ohms.

Although 130 watts at 4 ohms is not much power to run two cabinets I find. 130 watts of power is not big for Bass amp, but if it fits your needs, go for it.
