Audio sound problem

[g_kn]

Hi guys, connected a Sony headunit in my car.
The deck lights up and works fine.. except no sound.
Ill only get sound if i unplug all 4 RCA and replug them all back in.
I dont want to keep doing this every time i switch the car on.
Any ideas?
Thanks.

So you've been a member here since Jan 2007 and you still don't know to post this kind of question in the Audio section? :\

Well it still is a noob question. Relax.

Have you checked that when you installed the head unit the wires were connected up properly with the corresponding wires from in your car? Sometimes for example the black ground wire may not be black on the car.. if you get what I mean.

Take it back out and re-check its all connected properly.

r u running the rca to the amp for the speakers?
or you just running the speakers from the headunit power?

this will make r differece
