Need color code diagram for factory 8 speaker (this number also includes door tweeters from factory) system in a 4dr 1999 chevrolet tahoe. found basic GM wire diagram, but my system is different due to the factory amp! i have in front doors=6.5'' & tweeters factory; rear doors are:6.5''; and clear in back located in headliner are 4x10's i believe and cannot get them to work after replacing faCTORY head unit to aftermarket! i used all the correct harnesses and still no sound... except on occasion (lately anyhow)

You only have 4 speakers, 2 at the front (L&R) and 2 at the rear (L&R). What you think might be Tweeters are just for show and don't exist. :>D

Yes your speaker are bad I bought a 2008 tahoe changed the radio out same problem no sound install after market speakers and problem solved

The wires provided for a radio system are as follows:
yellow = hot with ignition key ON
orange = hot from BATT at all times
Grey = dimming power from instrument panel

Black = ground

Harness Wires provided for the speakers as follows:
Left rear speaker = +brown -yellow
Right rear speaker = +dark blue - light blue
Left front door speaker and tweeter = +tan - grey
Right front door speaker and tweeter = +light green -grey
Note: connection colors at the speaker location differ as noted:
Right front door = +brown -yellow
Left front door = +brown -yellow
All other speaker connections are consistent with their harness colors.

I just built a factory amplifier/crossover bypass adapter for my 2002 Chevy Tahoe Z71 (non-Bose system) . This adapter will allow the full range of audio directly from your head unit to the door speakers. Without this adapter, the factory amplifier will cut out much of the bass / low frequency audio to the door speakers. This adapter will continue to provide an audio signal to the factory amplifier for the rear factory subwoofer and cargo area pillar speakers.


I have posted an article with complete set of step-by-step instructions and detailed photos of the build and installation process.

The article also includes direct links to the exact parts that I purchased on Amazon to build this bypass adapter.


This is what the end result looks like. It is a 100% non-destructive adapter than can be installed or removed from the Tahoe at any time. It just plugs in between the factory wiring harness and the factory amplifier.

Good Luck!

Hi, your factory wire colors are below. Please let me know if you have more questions.

Everybody's got it wrong including the Mitchell manuals everything is reversed example left front door the gray is hot the brown is negative right front door dark green is hot light green is negative can't imagine how many cars have been screwed up because of this you can easily checked by looking at the old speakers and checking the tweeters if they have them they are labeled positive and negative take a 9-volt battery pop one of the speakers see which way it goes should pop out make sure that you wire the new speakers the same way oh my God there's so many of these on the market I can't imagine how many people have wired their stereos in reverse

I can email you the diagram...would be easier for you to see...but here it is in writing (we can't post pdf. files).

Right Rear Speaker-- yel/red & grey/red
Left Door Speaker -- wht/blu & blk/blu
Left tweeter -- org/blu & Brn/Blu
Left Rear Speaker -- yel/blu & grey blu
Right Door Speaker -- wht/red & blk/red
Right Tweeter -- org/red & brn/red

FYI - I just took our 2004 Sequoia in because of speaker rattle coming from the front door speakers. Before I could tell them the problem, they guessed what it was. They see loads of Sequoias and Tundras with JBL systems due to the front door 8in speaker, basically, coming apart. His suggestion was to replace only the bottom 8in speaker, because the top tweeters usually are in good working condition. There is a minimal failure rate on the tweeters.
