So I bought me a new set of Phoenix gold RSD 6.5 inch coaxial speakers for my car. Today I decided to install it into my car, I removed old factory speakers and since wires going into factory speakers was not red or black I took my multimeter and checked to see what wire was positive and what wire was negative. hooked wires to speaker and turned on my alpine cda 9886 and next think I know was that speaker started to smoke. I know for a fact that I wired the spaker currectly ( negative wire goes to negative on speaker and positive wire goes to postive on speaker ). rechecked the wires again useing my multimeter and wires was correct. My question is did I screw up or did I wire the speakers correctly?
