Hi, i am having trouble with the head unit in my mk1 golf gti! i have put in a jvc camilion head unit which i had in my last car, every time i turn it up to about 23 on a cd and about 24 on the radio it turns its self off and then comes on and then cuts out and this continues until you trun it down, now it seems to be getting worse, some times even level 19 on the radio will cut it out! its doing my head in, it worked fine in my last car! i have some jvc 6 by 9 s in the back and the standard poo speakers in the front! any ideas?? cheers rob
