fiesta sound system!!!

[aussie0001]

installd a sound system into my girlfriends car consisting of;
-splits in the front
-6inch speakers in the rear
-sub
-2channel amp
-4 channel amp
it was a pain in the *** to install but got there in the end and sounded awsome!!!

until yesterday she came home and said it all stopped working.
so i opend the boot and the sub had rolled over and pulled the earth out

so i reconnected the earth and it was all fine

now today she comes home and i checked it out again and the front left speaker was barley putting out any sound

so i swapped round all the speakers and tryd a few other things but it still aint working!!

its only the left + and - that seemd to be playing up so i try to run it off the 2 channel amp and the same is happening stuff all sound unless u bridge it or use the right terminal

please help
