you should install better wire with the comp. you have but won't change anything if u just cut the speaker wires.Make sure you cut the wire and join on the speaker side.
if you have short wires open the top of the unit , try to id the power wires . power it up and find your speakers and remote wire. then solder and heatshrink.
