you should have two wires on each side where you cut the plugs off. on the right you should have a brown wire with a white stripe and a red wire with a yellow stripe, one the left you should have a grey wire with a white stripe and a blue wire with a yellow stripe. the wires with the yellow stripes are your positives, hook them to the speaker wires without a stripe. hook the remaining wires to the wires with a stripe.

sorry if thats confusing, but you should have the following:
two wires coming from your right speaker, one with a stripe one without, the one without a stripe should be hooked to the red/yellow wire, the wire with a stripe should be hooked to the brown/white wire.
on the left you should have the same except the blue/yellow wire should be hooked to the one without a stripe, and the wire with a stripe should be hooked to the grey/white wire. make sure you do something with them, tape them or something until you can get some connectors
