Here's my problem. There is a constant hissing noise coming from my speakers. It's very constant and stable noise. When I turn off the headunit, the noise goes away because of course the headunit is off. By the way I have an amplifier running the speakers. I unplugged all the RCA and the hiss was still there. But I really don't think it's my amp hissing because I've had several amplifiers with the same problem. Here is my setup---------- speaker wires + RCA + remote wires on the right side. Power wire is on the left side. I also tried different ground for the amp and doesn't help. I also have a ground loop isolator and that didn't help. Please help someone. This hissing is really annoying.

Since you labeled your noise as a 'hiss' instead of a 'whine', and the fact that it is there even without the rcas plugged in, I would venture to guess you have the gains on the amplifier set high enough to allow you to actually hear the equipment noise itself.
All equiment generates a hiss type of sound when its on, some WAY more noticable than others. I would suggest trying to level match your system so that max output from the speakers is achieved right below max volume on the head unit. If you have any crossovers, equalizers, etc in line, this will only make the hiss more noticable also.

I don't have any eq's or anything and my gain is all the way down. You were mentioning about the alternator whine but I'm ok with that. Could there be anything else? thanks for you help.

My opinion: you have a faulty wire somewhere, grounding out on something. Thats why when you move the ground around, it don't help! Hope this helps and good luck

Check everything you can! If the car itself has a short somewhere, you can take it in and get a short test done to it. It's a special scanner they use, about the size of a cell phone, they walk around your vehicle, and it let's them know what area of your car, the short is in. Then they can address it. I had to do it once, cause I could not find the damn short for the life of me. Here in Canada it costed me $45.00 to do it, but it was worth it. Hope this helps
