does anyone know which is negative and which is positive for a 93? i have a feeling my wires are crossed.. i assumed the darker wire was negative. thanks for any feedback

the red or orange wire is positive. Go to installdoctor.com for a wiring diagram and color code

Well i just put Infinity Speakers in today. I think the 2 wires are brown and yellow. I am pretty sure that the yellow is posivitve and brown was negative. I will double check with my brother.
