got a call of a friend ,asking if i could hav a look at his audio in his of on the way home, put a multi meter across the terimals & thier was only 6 volts to both of them...closer look at the power cap find it hadn't been earthed at all but the worsr thing was the amps were not secure(screwed down)thing what had happenend is when he was driving home the amp slide in to the power cap & touched the terimals & turned the amps of...anyway i don't know why but after a bit of testing i got the amps working..so the idiot starts messing about with the wiring and touches the amp onto the power cap & shorts the system out & turns the amps of again,so my question is is the alpine amps gone back into safe astra...he tells me the his mate installed it all & was working fine bue it went mode & come back on or are they f--ked
