hey everybody today I replaced my Mach 460 headunit. I have a 2001. I used the Metra harness METRA 70-5519 FORD 2000-2001 AMPLIFIER INTEGRATOR PLUG. I have hooked everything up and only get sound out of the 4 tweeters, but not the other 4 speakers (subs)

The amp piece of the harness has 2 blue/white cables labeled amp power, and 2 grounds. I tied the grounds together and ran to chasse, and tied the 2 blue/whites together and wired into the remote turn on on the head unit. I verified voltage going from the blue/white to the remote turn on on the head unit. Also on the amp piece of the harness are RCA plugs, which I ran into the head unit RCA out. (which one should it go to, front, rear, or subs? It doesn't seem to matter )

I think the amps just are not coming on, I don't hear a click....or there is an audio problem. I noticed one of the wires / solder points on the amp harness piece was broken. There are a total of 8 pins I think.... 2 blue/white for amp turn on, 2 grounds, white RCA, red RCA, and 2 other black ones I believe are ground for each RCA. One of those black ones was broeken, would that cause this?

Any help would really be appreciated, I really need to get this up and running. I'm new at car audio and really need some help bad

 

well I was playing around trying things and all the sudden my key stopped working. I can't turn it either way I think it is a theft lock issue? Anybody know what is going on? My other key works still thank god. Also if I put the mach 460 head unit back in and connect the 2 harness wires and the antenna it will not come on at all

 

Can anybody help with this? I have great sound from the 4 tweeters just can't seem to get the 4 subs to turn on. I'm really stuck at this point
