Check the grounding on your 4 channel amp first. Make sure its grounded with the same length wire to the same spot in the boot as the monoblock. Make sure all paint has been sanded off the earthing point, then screw it up nice and tight. See how that goes. If there is still an issue, reground the headunit with its own stand alone earth not the original factory loom. Once again, make sure its bare metal, not painted metal. You may of had engine noise issues b4 the 4 channel amp, but u may not of been able to hear it through the monoblock due to a lower frequency output.
See if that fixes the issues. Also make sure that your earth from battery to body is good, clean and big. Once again, no paint, bare metal.

Whoa, dude that's a fire risk LOL
Run your RCA's down one side of your car and your power cables down the other just to be safe.
Make sure that none of your RCA cables or connections touch the body of the car anywhere, and none of your speaker earth's either.
Interfearance is usually caused by somebody bolting a speaker into a door and having the speaker's negative terminal touch the metal. Or the wires wearing where they exit the car and enter the door.
Also as mentioned above, make sure you have a very good earth on each amp, (back of the seat is ****ty. Use the boot floor)
If either amp or your deck has a crappy earth, it will try to use your RCA's or speaker cables to find one. The result is you hear the alternator through your speakers, That's why it only makes the noise when you start the car. You wouldn't hear this through the monoblock kos the alty makes a high pitched whyne. The low pass filter would eliminate it.
Basically you just need to tidy it all up, a LOT and your probolem should dissapear.
and if you still having issues, go to a car audio shop and get a noise filter for the back of the alternator.
Hope this helps

rcas are along the left of thecar, power on the right, i already said that didnt i?
i was looking at noise suppressors, do these work?? looks like a cheap fix....
ive got the earth cables hooked upto the baby seat thing, in the middle of theboot, took the bolt out of the top and put it throught the bottom with the tabs of the ground wires....
im starting to hear some low like stomach gurgling sounds when the car is off, this is really starting to gimme the ****s
