Hi,
I have a 1989 Ford Mustang and I installed wire connectors for my new head unit but I am not getting any sound from my speakers. I checked all of my wires and everything is wired correctly except the blue/white amp wire. Do I need this hooked up. If I do where do i hook it up at? I would like to get my radio working asap. It has 6 speakers in it. My radion turns on all of the speaker wires are hooked up correctly the only wire that isnt hooked up is that amp wire comming from the wire harness. Please help ASAP.

Thanks Much,

P.S. When i hook my factory radio back up it works again.

 

you do need to wire up the remote/amp turn on. there is a large octagonally shaped metal box with a bunch of holes in it below the radio, that is the factory amp. If you plan on running subs anytime you will need to bypass this or just as your subs are starting to sound good, your factory amp will already be distorting and sounding bad. If you follow the hrns that goes to it, you will find a standard for speaker hrns(70-1770). It is grey and normally in the dash, behind/below the glove box. It is a grey hrns that has 8 wires on it, if you look at page 2 of my cardomain page in my signature you will see me pointing to the hrns in my car. It is the same hrns in your car, just under/behind the glove box as I said. you can verify that you have the right hrns by disconnecting that hrns with the radio on. If you have the right one the radio will stay on and the sound will stop(of course assuming you get sound which you do not have at this time). Hook up the blue and white and then find/disconnect this hrns. If you get the 70-1770 hrns that is available at any autoparts store, you can connect the hrns's and then move it up to where the radio is, it will reach....... If you wire this hrns to your deck rather then the small black square one, you will bypass the factory amp and have better sound. It has never been easier to bypass a factory system on any car.... that hrns is the factory amps outputs that goes straight to the speaker.

If you are not running subs now and do not plan to, you can just wire the blue/white up and go. It will not sound as good as just running off of your new radio, but will not sound horrible.
