No signal

So I recently got all of my audio equipment in and I have everything installed now and I have no audio. I don’t have the jbl system that I’m aware of. I’m using the taco tunes harness to a Lc7i and then to an alpine pdx v9 amp for right now and the amp is turning on but the Lc7 is showing that there is no output signal. My thought is that I just have to unhook the stock amp but I don’t know other then that on why it’s not workin. Any help would be greatly appreciated lol

 

Not much help but I would like to see what the fix is

 

Did you splice into the stock amp?? When I installed my amp it replaced the stock one. Not sure why you would keep the stock one in the truck?

 

I ended up just unplugging the stock amp and then everything worked for the most part. I’m getting signal to all my speakers but for some reason I’m the front only 1 will play correctly and the other is muffled and then when I switch rcas it swaps so idk why it’s doing that
