Vibe a0 amp stuck in protection mode

[FlashRedThree]

Hoping somebody can help here. My sub stopped working and upon inspection the amp has gone into protection mode. I then found out that my earth cable had actually come away from its eye connection on the end that was bolted down to the chassis. This clearly is the problem, I thought.
However, after shantily wrapping it around the eye connector and electric taping it up, the amp is still refusing to come out of protection mode. Does it know that my cable is bodged  or is it fully knackered? I've tried it without speaker cables attached (just earth, +12v and remote) but it doesnt turn on at all unless i also plug in the RCA cables alongside these, and then it is still in protection mode.
Thanks for any assistance!

sounds like what has happened is that since your earth cable came away the amp had been trying to get its earth through the rca's
now obviously the earth on an rca is very very thin and not capable of supplying an earth and therefore you may well have blown the amp
the easiest way to check is to temporarily hook up another amp to your existing wiring and see if it works

I put my sub in my friends car and used his amp and it worked, so the sub hadnt blown.
I then put my amp in his car to power my sub, and it worked, so the amp hadnt blown (phew.)
Went to maplins and bought a new earth cable, and its all good again!

Cheers for the tip troublestarter.
