Navigator w/Premium Sound, No Sub

I recently added a new Head unit to my navigator with the Harness for Premium Sound I purchased from Best Buy. I have all the plugs but the sub isnt working and frankly the other speakers dont sound that great either. Anyone have any ideas why this might be happening or if you had the same problem how did you fix it?

Any help is appreciated

Thanks

So what your saying is the 3 pc harness I gto from Best Buy wont do the job. You dont happen to know the wiring config to do this do you? Or would I be better off just taking it in and letting the installers mess with it?

Unless it was released very recently and I just don't know about it yet, there is no adapter for the sub connector.  I am very familiar with Lincolns - indeed one of my specialtys is the Lincoln LS sound system, and the Navigator uses the same hardware.  Does one of the pieces you bought have an 8-pin square connector on one end and RCA's on the other?

If you take the truck to a good custom install shop, they can probably get the wiring diagram and fabricate a way that you can use the OEM sub.  Best Buy will most likely NOT be able to handle the job.

NO one end does NOT have the RCA's we have a shop here called Cars and Stereo's I think this may be a better job for them, thats ALL they do.

I dont have problem replacing door speakers, but I am not ready to tackle replacing subs etc, at least not until this one takes a crap on me, and then I might go with the the MTX Thunderform, but not real sure yet.

If you get your hands on any wirign diagrams, that would be great, I could use them

Thanks

Is your factory in-dash HU a 6-disk changer with "Alpine" on it?  What year is the truck?

Your factory head unit should have three connectors on it.  The 20-pin is the standard power/speakers, etc. that I'm sure the kit you purchashed from Best Buy attaches to.  There is a 16-pin databus connector for your steering wheel controls that you now cannot use, just leave that one disconnected.  The third connector on the Alpine systems is for the center channels (if you have them) and the factory sub.  Here's the wiring on that connector:

position 1 = sub R line level signal (gray/red)

The OEM sub in Lincoln autos is a 6X9 sub pushed by a 35 watt amp, so it will add in missing low frequencies but it will not "thump."

By the way, if you are interested in selling your factory Alpine changer, let me know as I may have buyers for it.

Good luck!

So what I should do is on the RIGHT RCA on the NEW HU I should cut that and splice into it? Correct? Memory serves me right I do NOT have center channel as the 8 pin connector actually only has four pins. So essentially take those 4 pins and splice in to the RIGHT RCA on the NEW HU and it should go? I want omake sure before anything gets cut :)

By the way, yes, I am going to get rid of my factory Disc Changer if you know anyone thats interested. Make me an offer

Thanks again

I was re-reading your post and think I just answered my own question,  but essentially splice 2 RCA's connect both outer rings to pin # 3 and the center Right to PIN1 and the center of LEft to PIN2 and then PIn4 to Remote.

I think I got it I will splice a par of Male RCA's and plug them into the deck to see if they work, Ill keep ya posted if your interested. My new deck arrives Wed. so well see what happens

Thanks

BY the way, if I want to change out the SUB do you have any good suggestions?
