Google Volvo wiring diagram. They are available free. The diagram shows the wire location and colors. Otherwise, run a continuity test with a simple meter to discover a connection with some resistance between a pair of wires. If you here a click or two, from the speakers, you have found the right pair. Continue and label the pairs left, right, front,rear, until all are identified. Then reconnect. A pain but not rocket science.

You can buy adaptor plugs that allow a simple hook up at most car stereo places.  However, when you increase the power going to the speakers you also have to replace the speakers to handle the higher power or you'll toast them.

you have to get the cable that conects your factory deck harness to the aftermarket deck, and that will allow you to use your factory speakers and amp, the wire harness is availiable at canadian tire or any stereo shop

Yes, it will sound horrible. like a opera on full treble sung by a mouse if it works at all.

Your aftermarket radio should have color-coded wires which identifies power, ground, speakers, etc. most depaetment stores carry a radio harness adapter kit. This will connect to your radio's exact color coded wires, and will plug right in to your factory's wiring plug. And don't forget electrical tape.
