Hi... This may get posted twice since I think I forgot to put in my subject line the first time. Anyway I have NOS (new in the box) of El Camino rear stereo speakers assemby it has two speakers and everything you need to install them including instructions. The GM part number is 996550. My husband purchased the kit from Delco many years ago when they were moving the speaker lines to Mexico. Both he and I are retired from GM Delco Electronics. He had an El Camino back then but he doesn't know what years these speakers will work for. We're cleaning out the garage and putting stuff on eBay. I will gladly share the instructions and thanks for any help.....June :)

Here is a link to a discussion on this subject back in 05. It looks like they are not for a 78 - 87.

I saw that post on the forums when I put the number into google. Thanks for effort.

I've found out what these speakers are for from 2 different ebay members based on the installation instructions that I pictured in my listings. They are for a 78 to 87 El Camino. Mystery solved..... 8)

:banghead:

No, the 78-87 El Camino wasn't offered with a rear speaker option.

Well based on the installation instructions that I posted one guy and said that it would work in his El Camino and the other said it was definately for the '78 to 87. I worked for GM for 30 years and I even worked in the speaker dept. briefly. I worked on Delco radios for many many years -- tuner inspection, final inspection, audit and shipping etc. Sometimes things are added sometimes names don't make sense. You may very well be right but so might those other guys. Tell you what I'll put the link here on my listing that has the supersize feature. I'm not trying to sell it here but I can't upload the picture here. Besides it's already bid up more than I ever expected....
The pix of the installation instructions are in the last picture.
I do appreciate your answer.

Or what you can do is just go out and buy the same speaker size and put it in the back your self. Simple as that and you will not need to go through all of this to find rear speakers. Second if you put rear speakers in you know you will be losing some storage space

What you're selling is a generic set of inexpensive 4x10" Delco speakers that, according to the instruction sheet, must be spliced into either a single front monoral speaker or dual front speakers with the use of an external fader control that looks like a potentiometer. Someone at Delco put together these kits, probably for many different models, each with their specific installation sheets. If it was specifically designed to be installed into an El Camino I think it would just plug into the rear speaker jack in the back of the Delco radio.

Sorry to burst the bubble but somebody is paying a heck of a lot of money for a generic pair of speakers. Caveat emptor.

You're so right. One day we're running Buick, the next Chevy, and then Pontiac. They were all the same radio except for the escutcheon. Cadillac Wonderbar did have its own line. The fader went in on some models if it were stereo. Quite frankly all the radios used the same technology. I worked on push button radios MTR (mechanically tuned radio) until the 80's then the ETR (electronically tuned radio) came out and I worked on them. I will say that Delco Radios were better than all the competition. I've been in a room with all the competitor's radios and nothing compared to the quality of Delco except when Lexus came out in the late 80's. The first transistor car radio was invented and built at Delco.
As for the speakers of course they made them to fit several different models. It would financial suicide to make them all different. Yep they were cheap. Making thousands a day does bring down the price.
Yes they're paying a lot for GM DELCO speakers made in the USA. Economics 101-- supply and demand. The speakers on eBay are not generic.
I retired in 1998. I doubt that any GM radio is still built here in the USA. I have a Buick Lucerne with a Panasonic radio and it's not that good of quality. I didn't know it was Panasonic until I was telling my neighbor that it just didn't have the sound quality that Delco Radios used to have when they were built here in the U.S. and he informed it wasn't a Delco Radio. He's an engineer there and it's Delphi now.
In case you’re wondering, I was and still am UAW.

Hello, Junebug, good info.. Maybe if you and your husband have any other {OEM} GM parts, would you be interested in listing them here first ? Just a suggestion ! THANKS !!

I actually had two of those speaker kits but I sold the other one just last week. I don't believe we have any more El Camino parts. Do have 55 Chevy, Nomand, and mainly '57 Chevy parts. The trouble with the '57 Chevy OEM parts is that we still have an original '57 Chevy BelAir Sport Coupe and hubby says maybe some day he might need them. He's had this car since 1975 and he ordered and purchased a new one back in 1957. So now that you've done the math, at his age, when is he going use these parts? At least I'm getting the garage cleaned out a little bit. BTW I didn't know you could sell them here......

The first radio I had in my El Camino was a factory unit out of an 87 Grand AM I used to own. I had to pull it apart one day and found out the CD section was Blaupunkt and the Receiver section was stamped BOSE.

Not bad names hiding under the DELCO brand...

:D

I'm surprised it didn't say Bose on the front of the radio. The Bose radios had a different speaker system than other radios.
After Japanese autos started to become popular the name Delco was taken off the front of the radio on the more expensive cars and eventually off all cars because GM wanted it off. I worked in returned goods(radios that were returned because the owner wanted to upgrade to a different radio or there was a problem with the radio etc.) Once in a while a dealer would send back a competitor radio. It was amazing to us how cheaply they were made. Too bad people tend to think that Japanese is always better.
Do you think in 50 years people will collect Toyotas?
