A quick look at the setup of my system. I have a Premier CD player about 9+ years old, Boston acoustic mid's and high's driven by a Kicker KX800.4. 12" Eclipse sub, driven by a FS BD1000.1. This is in my 97 Chevy Lumina. I recently swapped out my no-namer 4 channel amp for my kicker mentioned above. when I had the no-namer in my car everything worked fine. I had to run 4 gauge power and ground for the kicker. I had problems earlier with the kicker amp before I ran the 4 gauge wire. I would get a random static in my speakers and the amp would pop off and on. After running the 4 gauge wire I was still getting the static with smaller pops from the amp that sounded like a cd skipping. That wasn't due to a CD since I was using my Ipod. I was coming home the other day and it started popping off and on again and then nothing. The amp has power but no sound. Also there is always a delay before the music would start playing. I could hear my sub working before my mids and highs. Is that just something to do with my amp? Like a system check or something, or is it wired wrong? I ran RCA's to my Kicker amp that went straight to my Ipod to see if I could get any sound, but I got nothing. Please let me know your thoughts.
Sounds to me like the amp is fried... You stated that the no-namer worked, all you did is swap a problem prone amp in, and it worked for a little while, then didn't. There is signal coming from the deck, indicated by the sub making sound, but the highs don't. You ran a direct signal into the amp from a known good source, still no joy...
You have done everything anybody here would have suggested you try, and zero desirable result. Amp is DOA. Repair or replace.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
