i need some help. does the 2002 blazer ls 4dr have in dash speakers? its not the bose system but it looks like it has 4x6s or something in the dash i cant tell. i know for sure that it has rear and front door speakers im just unsure about the dash ones.
if it does have dash speakers, anyone know the wiring colors? because the wiring diagrams for everywhere i look seem to be LF RF LR RR but how is the in dash speakers wired?

I think it might just be tweeters in the dash with bass blocker in a 4x6 adapter plate. Now for the speaker wire colors, I am guessing the same as the doors.

The metra wiring harness for my 2002 came with a random loose red wire, about 16 inches long. It has a terminal on one end and the other side is just stripped. Any idea what this is for?

Man GM went buck wild with factory sound system options. My 1996 4x4 LS came with AM/FM/Cassette (but not the one with the built-in 5-band EQ). Apparently there was a base level AM/FM radio, a mid-level AM/FM/Cassette and an optional AM/FM/CD. I'm guessing that if you purchased the AM/FM/CD option, you got the 4x6" tweeters or was that part of yet another option called "Premium Sound System". I don't know if any of the 1996ers came with 2 or 3-way speakers in the dash.
So anyway, I have the fiber-board blank outs in my 4x6 dash pockets and there is no factory wire connector present. So it looks like I'll have to provide the wiring myself if I want to drop something in there AND I DO! The factory door speaker were probably fine for AM/FM/Cassette which didn't put out much high range anyway, but with a new Pioneer FH-X700BT HedUnit I'm sure that there's plenty of high-freq sound that's just not being reproduced by the original door speakers.
I'm not finding 4x6" blankout plates for mounting tweeters. Maybe I'm using the wrong search term. I just don't have the metal working tools to make them myself and I'm not inclined to anyway.
I guess this is a good place to relate my experience with the HU install. The Original Equipment stereo was only 5-1/4 inches deep. One thing I hate with a passion is the way that most speaker listings don't include a depth spec. The time-honored DIN standard doesn't and never did include a depth spec. So I blissfully ordered the Dbl-DIN Pioneer FH-X700BT and the Metra 99-1045 dash adapter and picked up a GM wire harness and antenna adapter at Walmart and thought I was ready to rock. Of course the whole scene took a nasty dive when I discovered that the 6-1/2 " or so depth of the Pioneer was too much to fit. I wasn't ready to take NO for an answer so I went at it with my Dremel. I cut a bunch of plastic out of the dash innards which was super risky because a large bundle of wires happens to be fastened to the backside of that plastic. Anyway, this surgery did what I needed and now the Pioneer HU is installed and looks factory fresh in the Metra 99-1045 dash mounting adapter.
Word To The Wise
Try to find a stereo with less than 5-1/2" depth or go with a Single DIN HU. A single DIN will require considerable less plastic cutting and the Metra 99-1045 comes with a pocket to fill the lower DIN space on Single DIN installs.
Bear in mind that this probably only applies to '94-'97 Blazers. Perhaps later models are more accommodating for deep head-units.

Try this link--->1998 Blazer Stereo Wiring
The constant 12V power wire in your vehicle is ORANGE, so you need to connect that to the 12V input wire on your new stereo. Your stereo may only have a single RED wire for that (depends on the unit). The YELLOW vehicle wire is "Switched 12V" so it only has power when the ignition key is turned ON or ACC.
Anyway the diagram at 12V dot com above shows what each wire in your vehicle does and your stereo should have come with it's own diagram so you can match everything up.

Is there a mounting kit for a 1999 with a 'pocket' under the head unit?
Websites are saying GM1583B is for '92+ but the first post in this thread says GM1583B is '02+

Very good decription but I would like to know this. I just hooked up a afterarket radio to my cousins truck tonight and it was playing through the speakers and then all of a sudden there was no sound and now cant get the sound to come back, what would cause this? And the radio still turns on and shows it is playing sound and isnt on mute so I am stumped.
