My Headunit Keeps Blowing Up!
Right, ive never had a problem wiring em in, got a Sony CDX-5000R 50W, disconnected battery, wired up ground to headunit, wired up the 12V constant, wired up my 6x9s. Connect the battery - jump back in the car, i hear the sound of the headunit trying to eject a cd breifly then nothing..
checked the wires - all correctly wired up e.t.c :dontknow: no idea!
Think i've blown the tiny red fuse that sits in the back of the headunit, can someone fill me in?

Well i've got a red wire with fuse box, a brown wire and speaker wire that needs to connect to the headunit.
The red wire with fuse box is quite obviously 12V constant and the brown is earth, i connected em up and it blew the fuse.
My headunit is a Sony CDX-5000R 4x50W, i've had it running fine in a 79 and 83 polo. Havn't replaced the fuse with a new one yet, once i get one ill try wiring it up again. Also got a spare shity headunit that came disconnected, will try to connect that and see if it works.

you need Constant +12V - Red, Ground -12V - black, and Ignition +12V - yellow, then your speakers, auto ariel etc, make sure you have an inline fuse on the Constant 12v+ as well as unit fuse. if it keeps popping fuses there is a problem with the unit. DONT KEEP REPLACING THEM until the fault is found. HTH :wink:

Ok well i've had alook at the wiring the only wires i've got are:
Red wire - 12V Constant, Black Wire - Ground
there is a seperate wire thats been removed obviously by the previous owner, its a yellow wire with a black pastic box on, do i connect this to the 12V constant and run it as an extra wire off that? - making it the ignition or not?

If the yellow wire is not connected then the head unit will not power up. The noise it makes when you wired it up initially is just the headunit "starting up" so to speak after being disconnected. If you connected the yellow wire to the red your stereo would be "on" all the time regardless of the position of the ignition switch. Ideally you need to find a wire that is switched by the ignition and connect that to the yellow wire. Hope this helps.
