My amp is an old Carvin PB900 which puts out "450/450 watts/Min. impedence: 2ohms ea. ch." which I'm assuming means that it puts out 450 watts through each speaker jack (since there are only 2). However I'm not sure about the minimum impedence being 2ohms. Does that mean the total load going through both channels has to be 2ohms (one 4ohm cab in each channel)? Or does it mean that each channel can handle a seperate 2ohm load making the total load going into both channels 1ohm? If it's the latter, then does anyone actually make 2ohm cabinets? Or would the only way to get the full power out of each channel be to daisy chain two 4ohm cabs per channel (meaning that I'd have four 4ohm cabs in total)? I don't actually have any intentions right now of getting more cabs. I'm just asking because this question's been bugging me lately.
