[QUOTE="soundstream5ch, post: 8361759, member: 664228"] Hi, I got myself a lc7i unit and I'm having a bit of a problem making it work. Let me describe the way I set up. I have a 2010 f150 with the basic stereo system (4 speakers). I bought a metra harness cause didn't want to cut factory harness. I also bought a speed wire (9 wires) to make it easier to connect the lc7i. So I cut the metra harness speaker wires (8 wires) and connected the speed wire which is pretty straight forward. Next, without cutting the red +12 volts wire (just removing some insulation) from the metra harness, I connected the remaining wire from the speedwire to it leaving me with one black ground wire and one yellow 12 volt constant. Then I brought all these wires to the lc7i proceeding to connecting them in the speakers input, and in the +12 volt input. Then I grounded the lc7i to a verified ground. Inside the lc7i the auto mode is on since I only have 2 speakers and I tried the GTO feature to ON and to Defeat mode and nothing is working! Is there anything I did wrong with my connections? Is there any other way I can try the lc7i to make sure it is working? I really need your help, thank you very much for your help. P.S. If you go to my profile, you will see a picture on how I wire all this. [/QUOTE]
