Hi This is my first post on this forum, and maybe it has been answered somewhere else, but I didn't really knew what terms to search for. Anyway I'm very interested in home audio, although I don't have the money to upgrade my old Technics amplifier and speakers. This is purely hypothetical, maybe I choose poorly rated items, but that is just to base myself on something. Let's say I have a Sony STRDE685 receiver. In the description, it says: - 5 Channel Power: 100 Watts X 5 - Stereo Power Per Channel: 100 Watts X 2 Does it means that having a set of speakers rated more than 100 watts, like the JBL ND310II rated 250 watts, is useless? But at the same time, does it means that speakers rated, for example, at 60 watts would break if the volume would be set too high? Another thing I don't understand. The receiver is 100 Watts X 5, so does it means that all the 5 speakers will receive 100 Watts of signal? If this is true, well there's no way rear speakers can handle the power of front speakers... and does this goes for the subwoofer too? Okay maybe I'm completely out of the track. All that watts thing is unclear to me. Thanks for helping me out. EDIT: I think I can kind of summarize this in one question: What specs should match between the receiver and the speakers?
