Headunit No Sound

[corpse.]

Hi thought id ask here before i pay $150 for the audio shop to put the headunit in.

I bought a JVC SHX855 headunit and for some reason no matter what i try i can't get any sound coming from the speakers? The headunit turns on etc etc and everything works within it but just no sound.

My cars a 1994 r33 4door gts.

But i tested something. if i run one of the headunits speaker wires through the blue/white cable on the headunit (its called amp turn on wire) i get sound?

do i need to wire up the blue/white wire to something?

I really don't want to pay $150 for the audio shops if its simply join it to a wire which is sitting right infront of me.

Oh and the previous owners cut the wires so i don't have the original plugs which sucks.

You must have it all wired wrong. What you can do is get a 9v battery and with the car off connect it to what you suspect are your speaker wires(make sure the deck is unplugged). You should hear a pop in the speaker. If you do not hear a pop then you are not connecting the right wires.

Are your speakers wired to your head unit or are they connected to an amp? Did you connect any RCA cables? By the sounds of it, it sounds like your speakers are connected to an amp and you are just not giving the amp the power wire(its blue I think, just double check, blue white is usually antenna power). If they are amped up, make sure the RCA's are connected and you are giving it amp turn on wire.

Any non f**k around audio shop will do this job for $60. Unless of course they need to run new wires to every speaker which isn't likely.

im running the speakers off the headunit. the previous owners had a crappy old kenwood headunit and cut the wires. Only thing i can think of is that the car use to have a factory amp but it was taken out?

and theres only 1 place in town that does the audio installs and they are charging $100 for the install + if they need to run any new wires etc etc
