OK, so to update everyone I stupidly took the installer advice, got rid of the supposed bad amp and bought a JL audio 600/4v2 (the amp with the highest signal to noise reduction in cruthfields catalogue that was under 600).

I put in the new amp my self using the old wiring and what do you know, the NOISE GOT WORSE.

I put in the new amp my self so I could answer some questions about the install.

The ground is bolted directly to the metal between the passenger seat and the door jam....under that plastic panel that pops out...he didn't sand away the paint...so fixing the ground is my first mission

The power wire is run around the back of the front seats to the left side of the vehicle then to the front and the battery, the RCA's and speaker wires are run directly from the passenger side to the front along the door jam and up to the deck. So in other words the rca's and power wires never come close to each other until they reach the amp. The RCA's and speaker wires are run together.

I am starting easy and working my way up, first I bought a JL audio ground bolt, I'm going to dremmel some paint away, and use the bolt to ground the deck and the 4 channel amp in the same spot (so I know for sure there is no ground loop)

Three questions I have are:

1) should I ground my sub amp to the same spot at the ground bolt or leave it the way it is?
2) is it ok that the RCA's are run with the speaker wire on the way back to the deck?
3) I believe what the installer did was run new speaker wire back to deck and spliced it with the old factory wire, instead of running new speaker wire to each speaker...could this be a problem?

Any help and comments would be appreciated, this noise is driving me insane...
