Need help!!!

I just bought an Alpine 9847 like a week ago. It was running fine and then it blew a fuse. Not on the HU itself but in the circuit box. I replaced it and it worked again. But like a half hour later it turned off again and switched fuse again but it blew again. Took HU out then put it back in and it was working again for a couple days. All the sudden it blew again. What would be causing this????

Which fuse is blowing? The constant or switched power? And what is the fuse rating? Does the fuse supply any other devices, like cigarette lighter or dome light?

make sure you don't have too much of a load on that fuse, i had a friend who had an audi and EVERYTHING was connected to one fuse. If this is the case i would run another fused wire or get a relay.... just my 2 cents

i'm not sure what fuse it is. It just says radio on the circuit reference. It is the one inside the car under the dash. it is a 7.5A fuse.

what does grounding out mean??? how does that happen???

check all your power wires 12 volt constant, ignition etc... make sure they are fastend tight and put some electrical tape around the connection. Your power wires are probably hitting a ground in turn causing your fuse to blow.

Thanks for the help. I taped all the wires away from the ground and it is working fine. THanks for your help. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
