is there a aux input kit or mod u can do to a 86-88 or that model era delco radio? ive searched all day and only found antenna adapters. ive also been looking for my blazer stereo too. thats a 98. only thing i have found for my generation of radio is a aux input converter for bose radios. or ones that have a cd changer with changer controls. nothing near what i have. my blazer has the aux tape deck. but for the late 80's delco's, i swear ive seen an adapter or kit to make a aux input for those radios.

There's no input on the back of these radios. So there's nothing to adapt to.

its an add on

Someone wrote up a little how to for making an input to the stock radio, lemme see if I can find it....

oh sweet. is that just for the 80's radios?

easiest is to get a wired in FM modulator. They go in line with the FM antenna lead and sound decent and do not have any problems with stations bleeding into the channel they are on. no modifications, just buy it asnd install it behind the radio, run the cable to where you want your mp3 player or satellite radio receiver.

No FM modulated does not sound as good as direct wired in, but on the Stock Fiero radio you cant tell the difference.

haha ya i know what ya mean! well it would be good to have untill i have enough $$ saved up for the stereo i want to do. its going to be a carputer....

I wrote the radio mod, along with another member providing pictures. While it worked fine when I did it to my radio, it caused problems with his.

FM transmitters and such generally don't give very good sound quality.

what mod was this?

ok, not sure which radio you have, but:

or this:

fm modulators work as well as those cassette tape adapters. fine if you like am radio quality. those above links cover it pretty well, all you need is a small tip soldering iron and about 5$ in parts ,

hmm, links. gaining more wrinkles on my grey matter....

I have the exact same unit in my car and it works just fine.
You might have to turn your volume up a bit. (It's adjustable on the side of the unit, too. Turn it all the way up when you install it.)

the12volt.com is just a great site in general. good info in those links! is there way to do this on the newer 95/96 later radios? like the pontiac monsoons or any other kind. like maybe even that radio that plays mp3's. i dont remmeber if that one has an audio input or not. if anyone has done it seen it done, that info would be excellent to have.

Actually the wired in version do not sound half bad, they have a wider bandwidth to them so they end up sounding a lot like a NPR station. it's the type that run off batteries that sound really crummy.

well i just found this. just not sure what models of radio it applies to

Someone followed my instructions...

so your directions would apply to any yr radio?? my blazer has the aux tape player. so i guess i would hafta see what wires are what on that. its a 98 btw. but i was just talking to my brother about a newer delco for our fiero's and he said he would like one. im sure he would love this mod since hes got an ipod.

quote Originally posted by Jax184: Someone followed my instructions...

I followed Jax184's instructions on my 84 EQ radio and had similar bad results as Fiero hoho.

Not to be deterred I set out to figure out why, and I discovered that as a cruel joke the Delco engineers labled the board the same way but the wires are not the same as the non-eq radio.

I set out to figure the correct mapping and I got it to work. I was going to post my results but haven't gotten to it yet.

wow, good on you. posted results would be great to have so no one rips their hair out, tosses their radio or kicks their neighbors dog, beats the wife and plays with the kids/beats the kids and plays with the wife.....lmfao. bootcamp had its funny moments.

oh and also how would i amp the regular outputs? if i remember right, the regular outputs are a bit too much for a decent sound quality as compared to aux outputs.

Okay, I'll save you from hoggin your own thread... By this evening I'll post the method that I used, based on the Jax184 method.

wow. did a search on the12volt.com in the car audio forum and got this

lots of good info!

***patiently waiting...foot tapping***

Ok, so where'sitat?

***tap, tap, tap....

yes....tap tap tap tap grumble tap ta.......ah crap, im starving.

I'm waiting also, kinda wondering if I destroyed my radio when I did the up-grade attempt or if it's still useable.

Hope he posts the fix as it would be nice to do this to the wifes GT for an upcoming trip.

shoot, be nice for any gm car. input that ipod!

Well we know my method works on the non-EQ version. For those of you who have one of those, you can go ahead and use my mod.

are there any schematics for any yr gm delco radio? i want some for any yr radio i get for both my cars. a monsoon sysem would look and sound great in a fiero....

Okay I was hoping to add some insight into this thread, but as I was playing around with the bare wires I shorted out my MP3 player...so now I'm kind of bummed out and don't want to mess with it anymore.

OK, so is it safe to say though that the actual audio wires you hooked into are in the same row of wires where the "L" & "R" marks are on the circuit board like in this pic?

Yes, but it was my experience that the wires marked "L" and "R" are not the correct one on the EQ radio. If you accidently connect the wrong ones you will fry your MP3 player. I'm still bummed about that. Trying to see if I can get it fixed as it wasn't a cheap one either.

OK, thanks.

I'll have to pull the old EQ radio out of the storage tote and put it back to normal, if it still works I'll try to figure out which are the right wires on the EQ style.

Man I'd really like to get this to work.

anyone know of any delco radio schematics? for all years. like 84-present

You and a host of others, fierohoho!

So we have the correct instructions on on non-EQ versions, working in the EQ version.

My GM9 AUX adapter works oin the data port in the back, but I am still ahving issues. An MP3 jack tapping directly in would seem to make sense. Has anyone done anything on adding a MP3 jack to one of the Pontiac single CD players?

if i could find some delco radio schematics, i could easily figure out how to do this as i am a electronic tech and i work with a bunch of electronic tech. i a aviation electronic tech in the navy. got all the tools and what not i need for this project. except the schematics. ive had no luck searching the internet. i think i reached the end......saw a lot of **** , and found out where jimmy hoffa's body is hidden....amazing but useless info one can find online! haha, ya, im a dork. a dork with a fiero!

ok, then, I don;t have an acdelco radio to play with, but that won;t stop me!
I went thru this finding wiring diagrams back in the 87-88 timeframe, they dont seem to exist, except for certified repair places.

So, if you have all the equipment, it should be a 2 minute job! Gotta teach these kids everything!

from that picture above, and from other radios I've worked on, you have an amp board or section of a board. they are ususally labeled, sometimes, even correctly.
So you set the radio up so it is safe to power on, power it on, put a tape in or hook an antenna up so it will produce some sound. you don;t need speakers, just don;t crank the volume, but do make sure it is at least 1/4 way up
Now take your signal tracer and with it in speaker mode, probe each line going to the amp board/section til you find the sound. use the balance to confirm wihch line is which channel (may not work on all setups, some put the balance in the amp section).
now if you don;t happen to have a signal tracer capable of audio, you can use the aux inputs of any amplifier, make a probe out of an old rca signal cable. the shield to a ground clip, which can clip to the metal chassis, and on the center wire of the coax, use a 0.1 or 0.01 mfd disk capacitor connected to it as your probe. this will block any dc voltage from thumping your amp too hard. Keep the volume low on your test amplifier, as it will be a rather high signal level usually. look for the sound,as before and verify it with the balance.
if you are checking the level with a scope, that point on most amps is in the 1v to 3v peak to peak range, depending on the volume levels.
Happy hacking!

And here I was, just about to suggest the same thing.
It'll take much longer to do this the "proper" way with schematics than it will to just poke at the wires.
