Is it possible to convert Bose Acoustimass satellite speakers for use with a normal 4 or 8 ohm amp?? My best friend has a yacht which came equipped with a Bose Acoustimass entertainment system. He likes the Bose systems (has one at home) but has totally given up on the one on the yacht. The Subwoofer/Control units obviously do not like the various marina hookups or the on-board generator as two have "gone south." Obviously the boat presently has no on board surge protection. He likes the Bose satellite speakers and would like to keep them and wire them to a normal reciever/amp. Each speaker is sealed with a four wire cable leading into it. Is it possible to connect them to a standard amp.???
