Alright, so soon my and my buddies will be jamming out, and recording a little bit of it (more jamming than recording) and I'm bringing over my audio equipment, plus all of our amps. We will be in a rather small room (size of a bedroom roughly, maybe smaller. As the room is at my buddies house so I do not have dimentions) and have a bit of equipment: 2 30w bass amps 1 15w guitar amp 1 65w guitar amp. another guitar amp prob around 30w A computer with a 300w power supply. and a 8 input mixer. a medium sized stero for listening sorry, most of the equipment isn't with me at this point in time so I can't check how many amps each pull. I don't know what his fuses are rated at but I'm assuming somehwere around 20-30 amps? The room being so small in probably on one circuit too. So i guess my question is, should I bring some extention cables and pull from other parts of the house with surge protectors? and how many amplifiers can I put per circuit?
