i just recently traded in my ford explorer for a 2004 saturn ion redline. Everything worked just fine in the explorer, but now that im trying to put my system into my saturn,nothing will work. i have hooked the wiring harness up and everything,but i am not getting music to come from my speakers. Another problem i am having, may or may not be related, is that when i have my power wire and ground for my amp hooked up, with the car not on at all, the sub will start hitting and the amp turns on and off, i have no idea whats going on... any ideas?
