Hi All im having some issues with my new headunit, it powers on but im only getting sound from the tweeters, all i did is connected the new harness ran the red cable to the fuse, however stopped a few hours later so i need to make sure the cable hasn't come loose from the back.

1 issue im having is i can only hear sound from the tweeters and not from the other for speakers (front / rear doors)

also the fuse on the headunit is 15 amp and when i used a dual piggy back on the fuse box i used 30 which is for the jet washers and 10amp in the other slot, Will that cause any issues? the one on the head unit is 15a.
