possible blue remote wire problem

hey whats going on.   i just installed a Cd player and amp in my truck.  ive had everything hooked up for a week.  there wasnt the first problem.  tonight on the way home my amp stopped working.  i checked the fuse, it was fine, even put a new one in.  i checked all the cables, nothing is lose or disconnected, i even pulled my cd played to make sure the blue remote wire wasnt disconnected. 

after all this i noticed that when i start my truck, the amp turns on for a second then turns back off, i checked the ground and when i touch it to the ground it comes on but goes back off, so im not sure what it could be. a side note:  the amp wasnt hot, no wire terminals werent burned or melted. soo i dont know.  any help will be appreciated.

grab a meter and meter your power and ground... do you have 12 volts on your blue remote wire?  do you have 12 volts on your amp main wire? does your ground connection meter as a good ground relative to the negative post of the battery or chassis?

shouldnt be too, too difficult to track down this problem......

BTW, dont  disconnect your ground when you still have the primary power cable hooked up.... thats just begging for disaster....

^^^^^^ I agree.

But didn't you say you can touch your ground and the amp comes back on?  Cause you said when you touch it to the ground it comes on and goes back off. Sounds like a possible ground problem. Redo your ground and see if that works, or see if its corroded at the grounding point. Your ground point has to be free of any paint, rust, etc.

A bad ground will cause an amp to turn on and then fizzle out.
