Hey, i'm running an amp that is 8ohms into a speaker that is 8ohms.

And i'm wondering, would it be safe to run a 4ohm amp into a 8ohm cabinate? would that destroy it in anyway?

that will be fine...it's called a safe mismatch. going up one 'ohm level' is safe. Examples: 4ohm head into 8ohm cab is ok...4ohm head into 2ohm cab is not. 8ohm head into 16 ohm cab is OK...8ohm head into 4ohm cab is not. It's always best just to match ohms if possible, but sometimes that's not an option.

quote for that link above:
'However, when running the head at a lower ohm rating then the cabinet, the result will be a significant degree of power loss. In the second case of using a 4 ohm cabinet with an amp that must be run at 8 ohms, this will stress an amp and cause it to overheat.'

My friend once said to me: Ohms into same ohms = full power. Ohms into less ohms = less power but safe. Ohms into more ohms = BOOM

How do the same things equal different outcomes

People would leave guitars for me in a box on the doorstep with a note "Please look after little Johnie, we just cant cope anymore, all he wants to do is hook up with Marshalls, We thought he would be a fender boy.

If you are running a tube head, you should really be matching ohms...


It's a solid state.

I always remember the bucket analogy. You can pour a 4 oz bucket into a 8 oz or 16 oz bucket without it overflowing. But if you try to do the reverse (8 or 16 into 4) you make a mess...
