Agreed with everything tbm has said.

Also, with the pen light thingo, it's easy to use for finding power wires and what not. You attach the clip to a ground point, such as a bolt attached to the body (or the body itself) and then poke wires with the pen. If it lights up, there is a circuit, so that wire is live. It's good for finding main power, acc power, illumination wire. Just find the one with power when the car is off, then find the one when the car is on acc, but turns off when acc is turned off, then find the one that turns on and off with lights.
But not helpful for speakers. A double a battery and tape and wires is though. attach some wire to each end of a bettery, tape it together, and you can find out which wires go to which speaker. The battery will make the speakers emit a popping noise. Not 100% sure if it's bad for them, so don't do it for long. Very handy for finding which cables go to fronts and which go to backs and what not.

But yeah, tbm is on the money for everything

Nice one drifter i forgot about the battery test, that doesnt tell you which is pos and which is neg tho does it? also id probably do it with the stock speakers if i was to do it, just to be safe.

with the test light he could still use it to determine which wire was which but he said his was missing the cable on the pen so i didnt go into it further. If you ground the test light and wrap the pos then neg wire onto the 12V constant then you can test which of the 4 cables are running to the headunit. that requires him to undo some of his harness tho so multi meter is better as you dont have to unhook wires to test.
