He's just trying to boost his post count by posting useless crap lol.
If you can get ahold of a multimeter and see if it's not getting either power or audio. That'll give us a better place to start
Ok. So I went back through the install and I learned a few things.
1. My truck either A doesn't have rear roof speakers or B someone had taken them out or disconnected them. I confirmed this by putting the stock HU back in and still no rear audio except for the SUB.
2.The sub will not accept an amplified signal from the Alpine KTP 445U and assume the same for any other amplified input.
So I ran the speaker out green/purplefrom th HU to the green/purple wires and as soon as I did the sub began to work.
I left it wired like that for now and the sound has improved slightly but I feel like I need more mid/high from the rear.
I will also be adding a real SUB because the stock does the truck no justice, but we all knew that.
Still a bit perplexed about the rear not being there or working at all. Is it possible the 2010 model had an option for rears and they are not there?
