people from best buy told me i had premium sound and said i need a premium system interface so i bought it because he said that if i didn't have it that my amp in my speakers would blow. So i hooked up everything correctly and only the power turned on, on my cd player and then i took the cd player back and the system interface back and retried it and the same thing happens. So is it the system interface that is messing up the whole thing and not working? Or they gave me a wiring harness that only has 2 plugs and there are a total of 6 in my car with the original radio and cd player taken out, but the guy from best buy said that was the correct one...so basically all I'm asking is why my cd player won't play the music but it is on.

 

the only thing that i can think of then is that this best buy guy is a moron

 

i was told that if i change the radio in my car it would have to be rewired because of it being a mach460 but i'm not sure if thats true

 

iv heard the same thing.....actually from a best buy employee as well

i would believe its true, as i cant really see a way around it, but there is a good article of how to

just add sum subs to the stock system here........http://www.mustangworld.com/ourpics/fcar/despeeds1.htm

 

It actually sounds as if the amps are not being turned on. Is it a "smart harness". Did you connect the harness yourself? Did you hook up the remote turn on wire? If you have the amps on, you should get sound. The other thing that you may be able to do is bypass the amp system. All the Mustangs with the Mach 460 system should have another wireharness in the dash from after the amps. You can unplug the speaker harness, and hook right in. Ford wired them this way because the Mach system was an upgrade, and they could swap everything out at the Dealer to a non Mach system if they had to.

 

It don't have the mach460 sound i have the premium sound atleast thats what the best buy guy told me. and yes i did it myself...and i turned all of the knowbs for the system interface all the way up and down everything.

 

JUST REWIRE IT!! I just finished mine with an apline CDA-9851 and alpine component type s' in the doors, took all hte mach stuff out, put the old speakers in teh back but without the box. And put in some real subs. The SQ is AMAZING!

 

I don't have any factory subs. It just came with the regular four speakers, radio, and cd player

 

Is the amp in the new head unit funcional?

If you just have the base stereo, there shouldn't be any special work needed.

 

I got it to work tonight..what I didn't do was hook the remote wire to the amp turn on..i thouht i just hooked that to my remote wire for my amplifier. Thanks for all of the help though
