okay I have an 04 grand prix. I have a sony headunit hifonics amp and 2 infinity 1260w subs. I had this system in my old car and when I took it out everything worked. everything still works my subwoofers just will not hit, my headunit turns on so does my amplifier. I bought some harness adapter (scosche) from Walmart and spliced every wire but 2. there is an orange wire and a blue/white wire not spliced. the orange is supposed to be for dash lights. yet they still work, the blue/white wire says nothing on it. not sure whats wrong or why they wont hit but I need help!
