I need help putting my aftermarket speakers in my 1998 Honda civic ex!!?

[Drew]

I bought some Sony Xplod speakers to replace both my front speakers and rear speakers. Problem is, my fActory speakers used four wires. My front left has two brown and black wires (one with one silver stripe and one with two silver stripes) and two orange and black wires. Same deal with the silver stripes =\ I need to find which ones are positive and negative so I can hook them up.. If anybody else had this problem, please help. I'd rather not have to buy more wiring harnesses for my speakers
