Frazled!!

Ok im all ohmed out... 2 inputs in the back of an amp....8ohms total.....so if i Plugged 2 8ohm cabs in this would then be 4ohm in put?? Id have to use 2 16 ohm cabs??!! My head hurts!!

Two outputs into two 8ohm cabs provides a 4ohm load. Usually.

If you have (for example) an amp which is 500W into 4ohms, you would get around 300W with one 8ohm cab and the full 500W with two 8 ohms cabs (a 4ohm load).

For the sake of clarity and defrazzling your brain...

Two 16Ω speaker cabinets will give you an 8Ω load.
An 8Ω and a 16Ω speaker cabinet will give you a 5Ω load.
Two 8Ω speaker cabinets will give you a 4Ω load.
A 4Ω and a 16Ω speaker cabinet will give you a 3.2Ω load.
An 8Ω and a 4Ω speaker cabinet will give you a 2.6Ω load.

If your amplifier states that it expects an 8Ω load then going below 8Ω is almost definately going to damage the amp.

If you're unsure what your amp can handle then tell us what it is and we'll see if we can give you a definitive answer.

If it's the amp he posted about recently then it's a Marshall valve amp.

It which case going above the stated impedance (or using it without an speaker connected) will fry it.

Quite so, But the power wont be evenly distributed between the cabs.
