Rodney - okay, as for what I replaced, that should be a moot point, here's why. I replaced it about a year ago and everything worked fine. I had a sirius that played through the FM and it worked fine . . . for the last year. I purchased a new SiriusXM radio to get the extra channels. When I was hooking up the new one, I sparked a wire and started all my issues. I have since got everything back working except for the volume.
Randy, I understand what you are saying but want to make sure I was clear. I am getting sound. My radio goes from 0 - 30. At 0 I can still here the music, it is quiet but NOT FAINT as I can definitely hear it. At 15 I can hear a tiny bit better but it sounds more like it would be at 5 or 6, not 15. At 30 I can hear it a little better still but not much. Going up to 30 at around 24 I start hearing some pops and static (speakers are fine, new speakers last year and used existing wire) but sounds more like 8 or 9, not 30. Amp fuse is fine. I guess I could bypass it and see what happens, but I want an amp so if it is fried I just assume replace it.
My concern is that I fried my factory amp and the fact that I get any sound is simply because it is wired properly. But, maybe if the amp was fried I wouldn't get any sound at all. I don't know enough to know that answer for certain.
One other thing of note. The volume issue is all the time. By that I mean that if I turn off Sirius and tune to a radio station it is the same thing. So it isn't the new Sirius. So I continue to
