unknown problem?!

From the sounds of it everything should be ok. Have you taken it out the car and just tried running power to it to see if it starts up? Maybe your power wire or ground or remote has a cut in it somewhere along it? Thats all i can think of.

i got new remote wire for it so that should be fine.
ground cables i've checked it all..
power cable i used a multimetre to test and it reads 12v so that should be ok aswell.

Is the remote wire connected to the back of the head unit properly maybe its coming loose when you put the headunit in the car. Sounds like everything should be working fine.
