sub disaster :'(
Alright, my friend (he is experienced in putting subs in cars) and I tried putting a sub and amp in my 09 focus se. It has the basic stereo so we had to take out th head unit and put in the line out converter. So he snipped some wires to get the converter in their and then he snipped another orangish grayish wire to fuse in with the power wire or whatever wire controls when the sub is on and off. So in conclusion the sub does not work still and now my passenger air bag light thing doesn't work right. Please help. Im stressing!
