The problem that arises is this: One buys an amplifier from the emporium,rated 1200W pmpo. It sports handles at each end by means of which it may be carried by two people, and a heatsink that would do justice to a Porsche. Someone has been telling the truth. To go with it one has a pretty pair of speakers, rated 1500W pmpo, with their 6 inch bass drivers and 2 inch cone tweeters, and sturdy 1/4 inch thick chipboard cabinets. Someone hasn't. Who is to blame for the smoke and confetti? Can one get one's money back?
