Not neccasarily, most amps can be bridged. As long as the impedence is right technicaly you could wire a multitude of speakers to a single channel of an amp. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifOriginally posted by jONnyBOi83 make believe each channel means speaker. so 2 channel means 2 speakers, 4 channel means 4 speakers, and mono means 1 speaker (sub). hope this helps.
