Yesterday I reconnected the speakers in the two front doors as the connection between the factory wire and wire to the speaker (aftermarket) seemed to be bad because they were randomly cutting out (wasn't conisistent, but just from time to time and volume level wouldn't matter) so I used a cap conector instead of butt connectors. I noticed when I stripped the wires they were no longer gold looking, but rather a brownish colour and looked burnt.

Im using an aftermarket Pioneer head unit and have replaced the factory 6x9s with pioneer 3way 220W and am still using the original factory speaker wiring w/ a wiring harness from best buy.

What is causing the speaker wire to look burnt? The sound quality still seems to be fine. Am i pumping more juice through the wires than they are able to handle?

too much current. They are overheating. YOu would need a huge amp to push enough power through with just listening, My guess is uyou have a short somewhere drawing the current

Yea we see this a lot with OEM wiring. Most of the time if you strip the jacket back a few inches the wire will be fine. It seams to happen a lot near the ends of the wire where they connect to the speaker. Most of the time it is because the connection to the speaker is not tight. When you see the factory speaker plugs on most cars you will now see some kind of Dielectric grease in the connector to help prevent corrosion which will also cause this discoloring.

Any time you have a break in a wire that is passing current (like a cut wire that was reconnected) that the flow of electrons has to cross if the transition is not smooth you will get a heat build up. That is what causes the discoloring/burning of the wire. I have seen a 4 ga power wire with less the 100 amps going through it look like someone held a torch to the end because the fuse inside the fuse holder was loose.

So to answer the question you are not overloading the wire you just need to check and make sure the connections to the speakers are very tight. You should not be able to wiggle them at all. It is always best to solider the wire to the speaker to eliminate ANY problem. But if you are using some kind of terminal connector just make sure it is tight!
