ok ok ok...even tho (several years ago) I did my physics A-level I still have a nightmare getting my head around this whole wattage/ohms thing!
Broken down: Low ohms = more watts get through = louder. I get that bit, maybe not the why or how, but I get that it happens.
Now, the big question...I've got a Hartke HA5500 (so that's max output 500w@4ohms but it's currently running 250w@8ohms) and I've got a VX215 cab thats rated upto 500w@4ohms.
So, they're matched, it should all work OK but on the speaker outputs on my head it's saying '8ohms'. Does anyone know how I can get the full 500w@4ohms? Will I need to send it back to the factory, or is there a secret switch I need to flick?
Any Ideas?
