Stock Head unit

[C_Nutz]

I have 2000 Lincoln LS, I am trying to add a sub to my exsisting stock head unit. Does anyone know whick wires are the correct ones to attach to or does anyone know the colors of which wire ( speaker, remote, power, gorund ).

[CGGorman]

Which system do you have (Alpine or not)? Factory "subs" in the rear deck?

[C_Nutz]

I do not have the Alpine system. My lincoln only has 4 speakers. If i am not mistaken , the alpine has 6 speakers.

[CGGorman]

OK. I have the same system. When I added my subs, I used the speaker-level inputs and tapped into the rear door speakers for a signal. I believe the colors were purple/purple&white and gray/gray&white. I pulled the B-pillar trim to gain access to the wiring before it entered the doors. There is an unused plug on the left sidewall of the trunk, near the seatback, under the carpeting, near the top. I believe I had to run a line to the front passenger footwell fusebox to find a switched hot for the remote signal. Power and ground came from the trunk, since the battery is right there.

What is the easiest way to get to the " B-pilar " and where is it ? Will I be able to get both channels from the area?

[CGGorman]

The B-pillar is the vertical structural member that separates the front and rear doors. The rear door hinges are welded to it. Just FYI: A-pillar is the vertical member that makes up part of the windshield frame. C-pillar is part rear glass/door frame...

To access the wiring, pull off the interior trim from the B-pillar and find the wires running to the rear doors. Splice into those.

I have an 01 Lincoln LS, i want to put subs in and i do have the Alpine HU. There is a 6 Disk CD Changer in the glove compartment. Does it sound fine if u take the signal from the speakers to amplify because i have only fed signal from preamps to the amplifier.

[CGGorman]

If you have the Alpine unit, you can use the preamp lines that feed the subwoofer unit. Otherwise, yes, the speaker level connection provides decent sound.

[01 Lincoln LS]

are the preamp outputs behind the headunit or is there an amplifier that the preouts are running to somewhere in the car?

as chris stated - if you have the alpine unit (with subs) here is the wriring:

Stereo Wiring:

According to the FOMOCO wiring diagram for 2000-2002, the factory harness connectors are wired as follows:

The large 20-pin connector:
Position 5 and 6 = right rear (- white and + gray)
Position 12 and 13 = left rear (- whit/violet and + gray/white)
Position 7 and 8 = right front (- white/red and + gray/red)
Position 14 and 15 = left front (- white/black and + gray/black)

Constant power = position 9 (orange.black)
Switched hot in start = position 3 (gray/orange)
Switched hot in run or ACC = position 10 (yellow/green)
Ground = position 16 (black/green)

The 16-pin connector contains the connections to the steering wheel controls and various data bus signals. The cassette systems with external CD changer have a connector dedicated to the signal cable for the changer.

On audiophile systems, there is an 8-pin connector wired as follows:
position 1 = sub + line level signal (gray/red)
position 2 = sub - line level signal (white/red)
position 3 = shield for sub amp signal
position 4 = +12 remote power to sub amp (yellow/red)
position 5 = center channel - line level signal (gray)
position 6 = center channel + line level signal (white)
position 7 = shield for center channel signal
position 8 = +12 remote power to center channel amp (yellow)

The trunk connector (on the drivers side) is number C465 and the sub audio uses these pins:
1 = yellow/red: switched hot
3 = shield for low level audio signal
5 = red: constant power from battery junction box fuse F418 (20 amps)
7 = white/red: low level LEFT audio signal
8 = grey/red: low level RIGHT audio signal

Ok, i removed the stock 4x6s and the box that iwas in, i wired the amp and subs. Everything has worked out great, But the subwoofer volume isn't great, My gains on my amp are set right and even with my bass boost knob up i don't get much volume from the subs. Is there an alternative to replacing the HU to increase the bass volume? Would i need to buy an EQ, and if so wouldn't that be a bitach to install because i am using all stock wiring except for the subs???

[CGGorman]

I can't help at this point. Haven't been there, haven't done that. Sorry. All I can put forth is to recheck your gain.

[Quik_LS]

an EQ wouldn't help.

I am running a Sony Xplod Amplifier/Subwoofers Package (XM-2165GTX amplifier / 2x XS-L1200B 12" subwoofer). Gives a good thump and shakes the car if I want it to.

try unplugging the lead to the right or left side amp input - see if that makes a difference.

[01 Lincoln LS]

the subs do work and decently, nice thump but not exactly what i was looking for. My last car was loud, ranked 140.3 DBs on a new mic. But this one isn't pushing much. Switching left and right RCA leads will not do anything. I have my amp pushing in mono, not stereo. I need to get something that will allow me to raise bass volume more, i will probably end up having to buy a new HU.

You might want to try to make sure that you have the polarity right for the RCA's. You really do not need to hook up both right and left channels for a sub. But, if you want to keep it that way, just unhook one and see what it is doing.

Also, you never stated what sub, box, or amp you are using.
