    My car is a 1997 Ford Mustang, and it just had the stock cassette player in it. Just recently I just went and got the head unit because it had the ipod input. After all the trouble of taking the old one out, getting the wiring harness, splicing everything to the input for the head-unit, no sound at all comes out. Everything else works fine though...I can find the radio stations, I can plug my iPod in and it detects it and starts playing. It will play CDs...there is just no sound at all.

    I am at a complete loss of what to do:wtc:

    That can't be it because the stereo turns on

    look, if you used a harness, hook the blue with white stripe wire up to the blue wire in the harness. this will turn the factory amps on.

    The remote wire only comes into play if he has external amps. Is the head unit on "mute"?

    Thats the only thing other than having the speaker wires connected wrong that would do that?

    yeah... and the odds are, since it's a mustang... it's probably factory amped... that's why i asked what i did.

    if it's not that, then there's a shorted out speaker.

    Correct sir. If the Remote on isn't connected, and he does indeed have factory "premium sound", the factory amp isn't receiving a turn on signal and isn't amplifying the sound. It doesn't sound as if this is the case, since he said he got the harness, etc, and wired it all up and plugged it in. If it were amplified, he wouldn't be able to use a standard harness, he'd need the amp bypass harness for his vehicle, which he did not say if he got that harness or not.



    If it is factory amplified, the amp needs the remote on wire attached (depending on the h/u, it's blue or blue with white stripe *your manual for the unit should give the color coding for it*). If it's not, you've got poor or shorted connections on your speaker plug/wires.

    it's also around that age range where some have 2 sets of plugs, amped and bypassed.

    it would help if we knew which harnesses he has, and if all the speakers played fine before the install.

    :bowdown: It was the blue wire that was connnected. At first I didn't know what it was so I didn't connect it. Thanks for the help OT!

    putting the factory back in(factory radios don't have a protection mode, like aftermarkets do.), and making sure every speaker was working... checking for shorted speaker(s), or shorted wiring... checking the pioneer for output... bypassing the factory amp, if it was the problem(which is rare, but possible.)... etc..
