If I connect just the hot and ground the Alpine still doesn't come on. I have the remote wire running through my LC6i and I think that might be an issue for the Alpine even though I didn't even have it connected for the RF since it had that AutoSense as a backup. I am off the next 2 days. Looks like I get to start digging into it. I rolled down my passenger front window and hear a clunk noise. I'm sure that can't be good. I will start there tonight when I wake up for the night. All this from sliding off the highway into a field. Go figure.
I'd disconnect the remote lead from the LC6i, connect it to the hot, and see if the amp powers up.
Thanks guys. I am up now and after dinner (breakfast for me) I will be at it in the garage. My remote lead is showing 9.9v when on and 0 when off. That is really weird. I am going to run it off the hot 4ga to see if it comes on. That should tell me if the remote is not working for sure. I added a tap fuse while I was diagnosing the Fosgate and that might be part of the problem too. My next step will be to take the LC6i out of the loop to see if I can get any sound that way, to make sure it is working.
Got an update. I ran a hot 12v to the remote switch on the Alpine amp, the light turned blue and went back out. The remote wire I had running to it only shows 9.9v and that is feeding off the LC6i. I pulled a high level input from my LC6i and ran it directly to the wires leaving my amp and running to the speakers. They all work but the passenger side front door, the one that had the clunking noise when I rolled the window down after the accident. The pillar speaker on that side works. I think I know what went wrong in the door but I have yet to remove the door panel. I am taking it off now. My question is, if the door speaker is damaged and shorted, would it have cause problems with my LC6i? Like killing all the signals leaving it and going to the amp? I took it out of the truck and opened it up and nothing looks amiss, not that I would really know if there was. My plan so far is to fix or remove the door speaker that is damaged and connect everything back up. Will post more later.
I pulled the door panel. Speaker works when out of the door, no damage to it. The pigtail on it was kind of iffy so I redid the ends. They are good and solid now. My glass was getting caught on the wire harness to the speaker when it was rolled down. No damage to the wires but when the speaker is plugged in there is no sound. I pulled the pillar down thinking it might come off the tweeter but it doesn't. Still working on it. I took a pic of the inside of the door where the wires go into the body and I don't know if this is normal looking but it looks broken to me?
Found the problem in the door. The factory plug had a broken wire. Snipped it off and put another plug on it. Door works like a champ now. However, I still have no working amp. Here is where I am at:
The 4 high level outputs that go into the LC6i are putting out a signal. I ran each to a speaker and they all have sound.
The LC6i has a red power LED, 2 green "connected" LED's and a yellow "Maximized" LED. Only the red power is lit at any time.
The amp has 4ga 12v and negative run to it. Volt meter verified. The remote voltage coming from the LC6i was only 9.94v coming out but 12v going in so I bypassed the LC6i and ran the remote 12v straight to the amp. With only the hot, neg, and rem 12v running to the amp the blue light comes on for a brief second and then goes out. If I connect all the speakers it does the same thing no matter if I connect 1 channel at a time or all at once.
When I had the wreck my truck shutoff and the display said to take it in for service or something like that. It was quick so I did not get a chance to read it all. I turned off the key, removed it and restarted it and it has run fine ever since, no CEL or anything. Is there a way to recall that message? Since my radio was coming on and my truck was running fine and the message never came back, I assumed it was ok.
One last thing. About 30 minutes after I started working on this (doors open and stereo on (no amp) I got a message telling me to conserve battery power and turn off the key. That has happened before but it seems to me it is usually alot longer than 30 mins or so that the message happens. After working on this for a few hours and letting the stereo run my battery was low and when I started the truck you could tell it was indeed running low of charge. This is a 2014 and this is my factory battery. Could my problem simply be my battery? I don''t really think that is possible since it still does this when the truck is running.
So you took the LC6i completely out of the equation, and connected the speaker-level outputs from the factory system (which you verified are working) to the Alpine amp's speaker-level inputs, and still don't have any sound from the Alpine? That's a real head-scratcher.
I'd call Alpine and explain your power light scenario. That sounds wonky right from the start.

No, I can't connect them directly to the amp because the amp only has rca inputs from the LC6i, no high levels. I disconnected the high level inputs from the LC6i (they come from the HU to the LC6i) and connected them to the speakers directly to make sure the signal was getting out of the HU and the speakers worked. Essentially I took the amp and the LC6i out of the equation but the amp has been replaced and even the new Alpine does the same thing. I thought about buying a set of those rca cables that convert high level inputs into RCA's though and ditching the LC6i. Truthfully, I think it might be bad.
I do have a power issue though. After working on it my truck had trouble starting. On my way to work tonight my OEM HID's would not come on. I was half way to work before they would ignite.
