im confuzzled, Amp gets power, but when grounded it doesnt? Options

[LimitedST]

Alright. im waaay confused.

Heres my situation
i got my amp in the trunk.
The power from the battery in the engine bay travels from their to the trunk. the coords from the head unit also do the same. Now the grounding wire that came in the rockford fosgate amp kit, is only like.... 8" long, its not going anywhere but in the trunk.
So, i found a screw already grounded, inside the place where the jack goes, put the ground wire there, gscrewed back in... no power? decided it was a bad ground.
moved it. drilled a tiny little hole under the carpet, next to the place where the jack goes. screwed it in. no power?

unscrewed it. turned car on. it has power....

The amp will turn on when not grounded, but when it is grounded it wont turn on.
The amp will turn on, but wont send signals to my speakers or amps. so i dont know what its doing.
im really confused. and any information would be helpful! thank you.
limited.

fye amp = p3002 subs = 8" phase 1
speakers = 6 x9 40ways

rockford fosgate of course

okay here is my crappy drawing.



now if the GND isnt connected, the amp will power up, but wont send signals cuz the thermal light is ON.
if the GND is connected, the amp will not turn on at all.
If the GND is not connected, and i have 1 speaker connected, i get the same results if there was no speakers connected, or all 4 connected, no signals sent from amp to speakers/subs.

The head unit has 3 wires comign from it. 2 of which look like sumthing you would connect your PS2/xbox to your tv with. with a red + white end. and then theres the really small little skinny one too. which is labeled REM on the amp. the red and white are labeled IN. right next to the 'IN' area, theres two more spots for a "pass thru" which im not using cu i dont have another amp. Right of the "in" spots, is there you connect the (in order left to right) REM -> GND -> B+
left of the "in" theres (fromt right to left) a little knob for cross over -> the boost controller plug in -> speaker 1 + - speaker 2 + -

so yeah. thats what my drawing is. and is exactly how my car is set up right now.
ill get batteires when i go get my new razr since my phone broke.
