I used to own car audio stores so this is double frustrating. I have a 98 with the 460 and the right side is not playing through the Metra harness adapter and aftermarket deck. I was thinking the front amp was the issue since both the front and rear sub and tweeter are all not working on that side. I read the front amp pushed signal to the rear amps, if that is the case then it would make sense that is the issue and the front amp has a fault in that channel and isn't feeding the rest of the car.

I am using the Metra harness that is just wires, not RCA's and still not getting any signal to the right side of the car after verifying the harness is making proper connection.

So this harness which is just wires. I know to step the voltage down so thats not an issue, I simply am not passing signal.




Anyone care to chime in on the front amp possibly not working on one channel and not passing signal along to the rear? That's all I can think of for the entire car to be dead on the right side.

 

I needed to clarify that the problem is that when I fade to the right I hear no sound at all. The tweeter and mid in the front door play very low volume when balance is in the middle. The left door is as it should be.


Unfortunately I didn't find anything obvious with this front amp. I have my o'scope if i need to dig around in it, but I'm hoping someone has some insight on the amp inputs so I don't have to probe this thing.
