Hi. I have a stereo that has 4 outputs for each speaker (separate +/- outputs for high & low range). Someone has given me some better speakers than the ones that came with it but those other speakers only have the two red & black wires... Can I connect those speakers to that system instead and have them receive both high and low range? Any ideas? I'm a real rookie to this stuff and don't want to wreck any of my gear but hopefully there is a way? Thanks.
