Quick wiring ?

[singlehanded]

I putting my alpine type-r front pass. speaker back in it has a crossover that I thought was bad so I took it out. Ended up being the amp, so I am putting it back in. I Know what is the power and groung on the x-over but not the two wire coming out of truck stock speaker wires. Is there any way to figure it out easily and quick hopefully? One is orange with a green lin and one is light blue with a white line. I already took the pass. door apart and the wires were different colors. Any help please.

Ps it the f150

orange will be positive and blue will be negative. Not 100%, but that sounds right if I remember correctly. Also if you checked the other door you could tell.... the darker wire should be positive and the lighter color should be negative. If its vise versa on that side then blue will be positive and orange will be negative.

Thanks, I already figured it out the first night, but I found a nice single 10" sub box on the site that will fit perfect under my rear seat with my amp.
