Doulop rear Bose speakers with amp $213.99 each. Ecklers. They match OEM. My dilemma is the CD player is not working which might be the head. Expensive, $227. My radio works fine. Regarding your problem, Delco/Bose has a radio receiver refurbishment program via Ecklers as well. $134.99. Sounds like your receiver is shot. Call 877-815-5799 for complete details should you decide to refurbish your radio. Love my C4 and I like to keep things OEM but I may look to buy a modern radio and speakers. It will cost me almost $700 to restore it all to OEM. Maybe a new unit with Bluetooth and sync would be a better return on investment.
what a blast from the past! I won't look ahead so as not to spoil the outcome. I also have a '91 that I used to use as a daily driver. I bought her used but she was cherry and needed a lot of TLC at first.. for which she rewarded me well with many dependable miles. But from day ONE.. when I turned her stereo on.. she SCREECHED in four channel pain! Seriously. I only turned on her radio a couple more times to know that she had a serious flaw in her stereo system.
I appreciate the way you approach diagnosing this sticky problem and also share your frustration. I have a '91 Corvette Convertible and the radio stopped working a couple of years ago. I have been avoiding fixing it, but your video has me motivated. So thank you for that. My radio's symptoms are different from yours where my radio turns on and the power antenna operates, but only a high pitch static noise comes out of the speakers. I also thought it was the CDM. It is a shame that it is such a pain to access it. I live in Syracuse, so I'm planning to take the CDM to a local automotive electical repair shop, United Radio. So as soon as the weather warms up I'll let you know what they find out. I'm just hoping it isn't too expensive. Keep us apprised of your progress. Lastly, I agree with you that Corvettes need to be all factory stock.
Hi Chuch, thank you so much for your kind words. I still have not fixed this issue. I need to send my CDM to Dr. Don which is a well-known Corvette radio repair man and have him repair mine back to factory. I just hate to spend 200 some dollars for a radio. Hopefully sometime soon I can do that. I hope you get yours figured out too. Thanks for commenting and take care!
I haven't pulled the CDM out of my car yet. With today being a pretty nice day I went out to the garage, lifted the car cover and surveyed the situation. I noticed that the glove compartment is located directly above the CDM general area. It looks like taking the glove box out looks pretty simple. Before I start that task I thought I'd ask the question: did you notice in your efforts if the CDM can be removed from the glove box opening? Thanks.
So glad you asked. No, it needs to be accessed from below. You can access it from on the ground. Just a pain. Good luck, Chuck! Let me know how you make out.
@@Doulop Thank you for being so responsive, that will save me from doing a useless task and just wasting time. My plan is to start with disconneting each speaker, then systematically reconnecting each one to see if there is one bad speaker. The symptoms: I get power to the radio head which lights up and the power antenna goes up and then a loud squeal. I'm hoping that by disconnecting each speaker sequentially I can determine if it is one or more of the speakers or none of them, leaving the CDM as the problem. In which case I'll need Houdini lessons. Thanks again, keep your great videos coming.
Hey Chuck, not a problem :) your plan sounds like the perfect way to approach it. I get nothing at all so I can’t do that. I wish you best. Please continue to keep me updated and good luck on the Houdini lessons :)
Doctor Don is the man Doulop. Going to send him my radio for service. The cassette no longer works and the radio receiver sometimes goes out and switches to cassette. If you hit eject it may or may not come back. The CD works though. I might get his CDR or MP3 connection to upgrade. I have seen many owners go with the touch screen radios or GPS in their cars. I really don't want to modify the inside of the dash mounting area and mess with a lot of wiring. Finding a place to install a new radio where they aren't a bunch of hacks is a concern if not doing the install yourself. Best of luck with getting your radio fixed. Doctor Don set up my friend Charlie's 92 ZR1 and it's great with the MP3 hook up.
Hey man, I’ve heard fantastic things. I am trying one more thing this week and if that fails, I will be sending to Dr. Don. :) good luck with yours as well! Take care!
Dang dude wish I knew you needed one. I pulled one out of my corvette when I went aftermarket and am having a problem selling it. The radio worked when it was in the car.
Hi Josh, at this point, I don’t know what the problem is. I replaced the CDM and it didn’t fix it. Could be ground or maybe the head unit. I have no clue. Very frustrating, though, thanks for your comment. Merry Christmas!
By some miracle, my '93s stereo system still works! I bought her used and when I first turned on the radio and it didn't work.. even thought the antenna DID.. I wrote that off to the awful experimental radios they made in the early '90s and bought the car anyway.. after all my '91s radio was burnt toast.. but I didn't miss it much. But after a few hours of driving my "new" 93.. I decided to try the radio again.. and again.. nothing.. but at least it didn't screech.. so I left it on.. Then after maybe 30 seconds, the rear speakers came alive. Cool! So I tuned in a radio station and it played reasonably well.. when two full minutes later.. the FRONT speakers came alive! I could not believer it! I KNOW that each speaker has it's own amplifier.. and it won't last for long.. With the hard top on and the windows rolled up.. it is like a huge pair of quad headphones.. as good as you would ever expect from a stereo of the era. Am I gushing? Nope. I haven't even mentioned the CD and tape player that still works as well. NOW I am gushing!
The original CDM you took out was a reman unit also. United Radio out of Syracuse New York. I live in CA but not about them from Eric O at South Main Auto. Good luck! Hope it works for you. I like stock also. Aftermarket looks cheesy and out of place.
My '91's stereo never DID work.. so I just never used it anymore. I found the C-4's original muffler system's natural hum to be music enough. But as fate would have it.. years later.. my red C4 was rendered totaled.. by a deer. Anyway.. I was fortunate enough to find another C4 for a reasonable price right after the mishap. This C4 is a '93.. two years newer.. and four years better. One way better is that the stereo still works! It shows every indication of quitting at any time.
Hey bud, don't loose hope. BTW, when ever you tinker on the car and find messed up or wrong hardware, rune to the car place and get some of the correct ones. Will make working on the car easyer and will take the 'Bubbaness. out as The Corvette Ben would say. I did on mine.... A LOT!
'91 C4, my CDM has a plastic cover with all kinds of wires attached to bottom, got most off, but don't want to break clips on last 2. This has been a bear to just get to the CDM, I wish mine was like yours with out the plastic cover. I'm afraid of damaging the thousands of wires they shoved down there and under the CDM unit. May change mind and just run new wires/speakers to go with my new radio.
Did you solve your radio problem? I to have an issue with my radio. It will blow the 15 amp fuse in position 1 at the fuse panel. Designation under fuse is CTSY it handles interior lighting speaker relays antenna and air cond. (c68), interior and interior lighting. I have all refurbished speaker amps and radio from Bose and have replaced speaker relay and did trouble shooting on antenna. Can’t fine any damage wiring so do you believe my next step would be the CDM? I am at a lose.
I am having the exact same problem with my 91 Corvette. The 15 amp fuse blows when turning the ignition on. The radio works if you replace with a fresh fuse, but will blow the next time the ignition is turned on. Did you find a fix yet?
Is it fixed? I’m sure there’s a bunch of us that want to see it working, love to watch videos where there is not immediate success. Seems like more true to my life’s experiences 😉 My Used C5 came with a 12 cd changer in the trunk but was missing the magazine and now they are obsolete or cost more than I am willing to pay for used on eBay 🙁
Not yet but I had a subscriber the other week tell me how his did the same thing and it was just A loose antenna. I plan on doing that here in the next few weeks and I’m hoping it is the fix and there will definitely be a video about it. The first Corvette I ever drove was a C5 and it had the CD changer in the back as well. Very weird spot for it but hey, it worked. I hope you can get yours to work at some point. Yes, I agree. I like being able to show the failures as well as the successes. That made me laugh
@@Doulop Did they say anything specific? Like which antenna connection or generally where? I've been battling this issue as well and it sucks, I sent my CDM out last week as a core. I just wanna hear some music in this thing.
You can send the radio to Ecklers and get it refurbished and buy new speakers however I found that investing in 90’s tech is numbers matching but not the best choice. I’m installing a Kenwood with Apple Car Play, Bluetooth, back up camera for less than $1,000
I'm all for keeping my Corvette all original also but you got to do some upgrades and enjoy the car , you don't have the original wheels on that car,you can put a nice double din radio in that with a screen and look beautiful,just keep all the old stuff for the radio if you sell the car you have it....
A big shout out to Daisy Mae! Hey girl! Contact your local Corvette Club and I bet one of the members would love to give you a thrilling ride in one of the member's Corvettes. Make sure to wear your Depends for the ride though!! ;)
I had a 96 with radio that would light up, buttons seem to work, but no sound. My problem was the wires to the Bose relay. No power was getting to the speakers which should read 12v when radio on. If you got nothing, then check the relay. The main orange +12v lead was bad. I ran a new wire from the hatch light. Then I found the blue "turn on" wire from the CDM unit was bad. It would work intermittently, not getting full 12v signal to the relay. Ran new wire directly from CDM to relay to bypass bad wire. This fixed my problem and got my stock unit to work. I was going to switch to Android, but when I saw my stock worked, I kept it and just paired it with a FM bluetooth transmitter and my iphone Velcroed to the status display screen to give me the same functionality. Maybe you have a similar problem with "bad wires". Took me 3 weeks to figure this out!
@@Doulop I saw this in a forum post: Do the wipers work on the car? On my 1990 (same bose) my cd/cassette used to only display the time. There is a white wire on the CDM tuner that is a source of ignition power and if it isn't present only the clock will display. This wire is tied into the wiper fuse. The radio fuse is only for battery power to the CDM tuner. There is also a bose power amp relay mounted kinda by the steering column as well as a ground wire kinda right by the place where the door wiring passes through the door jamb. www.digitalcorvettes.com/threads/1991-coupe-radio-not-working.154737/ That sounds like your problem. Also look at wiring diagram: www.digitalcorvettes.com/threads/radio-wiring-diagram-for-a-1995.250610/ There should be a wire which is only hot when the ignition is on. If you don't find it, that is probably the problem and you have to run a new wire.
I just installed my bose front unit after removing the working aftermarket one but it doesn’t work either. I’ll check the fuses. The guy that sold it to me didn’t even know if it was working or not. Anyway I’ll keep it like that just for looks
@@Doulop thanks. I’m waiting for the service manual to arrive and i’ll see what is recommends, probably the cdm is bad. I have the clock when I push the top button but it turns off after a few seconds, the cassette eject makes a sound when pressing the button, the buttons backlight works well, but nothing else, the buttons state leds don’t light up. one thing I could do is to check the harness between the cdm and the head unit but I’ll wait for the manual
I just purchased a 91 C4, and my stock radio is not working when I cut it on I’m getting a squelching sound coming from the speakers… I feel your pain still searching for a fix… I might be forced to go after market… My antenna is raising up and everything but still no music just squelch! Help! SOS … 😀
I really enjoyed your vid! I'm on the fence about buying a really nice 96 C4 or 5 to 10k more on a C5. Just curious when the top is on at highway speeds do you get a lot of creeking or flexing noise?
Thank you very much, Rob. Honestly, I hardly ever have my top on at all. When I have had my top on on the highway, the C4 is a very quiet car in the cabin. I don’t recall any creaking or flexing noise whatsoever. When the top is off on the highway, the only noise I can hear is wind noise. When the top is off and you’re driving over potholes and stuff in towns and things, you get a lot of creaking and stuff but it’s an old car, I don’t really expect it not to.
I am terrible at electrical stuff. I put a test light in all 5 of the harnesses that plug into the brain and one of them had the light come on. That’s it. Thoughts?
I’m old school. I use a old analog volt ohm meter. A test light proves you have power, but if you have a bad ground wire you would never know. Just a thought. I ALWAYS check for power and ground before going further.
Hey man My radio isnt working either, but my radio will light up, I just sent in my cdm to get rebuilt, since you’re didn’t work should I look into replacing my antenna? Thanks!
Hi Reese, my antenna was replaced with a brand new one back in 2014. I don’t think my antenna is bad but I did have a Subscriber tell me that his antenna was loose which was causing a ground connection issue and wouldn’t let the radio come on. He tightened up the antenna and everything worked. I have not gotten my car out of storage yet but I hope to do that soon. Best of luck with your radio, man. It is very frustrating when your radio doesn’t work. Thanks for watching
I think that's high. Buy one from someone that has kept the receipts. I personally wouldn't pay 10k. There's a ton of Vette's for sale, take your time. You can get a nice one for 7-8K.
@@Jeepfeenz Whomever you decide to purchase from, make sure to get a pre-purchase inspection. I guarantee you, it needs some work! After the inspection finds what needs done, you can use that info for bargaining. Or you may want to walk away. Whatever you do, get an inspection!
Is it worth trying to get my factory radio working? or should I just buy a new head unit... i get pretty bad sound from front left, decent sound front right, no sound rear left, and sometimes i get pulsing noises rear right.. I have a feeling it's not speaker related because I tried some known good speakers in the back and didn't have any luck.
Honestly, if you don’t mind going away from the stock look, you will get much better sound, technology and convenience from a new system. I just like the stock look too much to do that, personally. I wish you the best. It’s annoying not having a working radio!
I have a 92 left side speakers don’t work and the antenna works every once in awhile I had the radio rebuilt in 2014 when I got the car thinking about just going aftermarket
I have not. To go further requires money and I don’t have that to put into a radio right now. Big bummer for me. I am sorry I didn’t have a follow up to this yet :(
Hi Eric, actually, no. These were the power sports seats that were available that year. The later C4 seats are nasty looking. I am glad mine are what they are! Merry Christmas!
Hey Shane, what do you mean the lights are screwy? I recently had my headlight switch out just to clean it but it didn’t fix my problem. My headlights work but my dash lights never come on. Sorry man. Wish I could help :(
There is a module for instruments gauges I find out I’ve ordered one I’ll let you know how it works out ., also if you shine a light in the sensor your dash lights get bright
I’d go to a junk yard and get one out of another corvette to see if it works before spending $225.00. It’d prob cost $59 or less maybe. Idk for sure, just guessing.
Hey Ryan, it is 10086210 but that part number looks slightly different for different years.. Not sure if you are wanting to order one but here is one on eBay. Thanks for watching! www.ebay.com/itm/194092144782?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=iUOVNxJWSOC&sssrc=2349624&ssuid=rQmFyXNUTMS&var=&widget_ver=artemis&media=COPY
That is crazy! Makes no sense. Make sure you take the radio and the brain in as they require both pieces to work on them! I hope they figure it out for you
C4 Corvette Forum ....C4Corvette 1984-96 .... C4 Corvette Problems / Fixes ...are also very good ...Jeremy check out the last one maybe someone can help with your radio issues :)
I am sorry but no. I got so frustrated with it that I just buttoned everything back up and said forget it. I hope you can figure yours out. If you ever do, let me know.
@@Doulop 1994 ..and that was 5 years ago...I got a discount at the parts counter using a friends name using his garage discount then taking it over to the service dept..I know the guys at glenway chev so they have no problem with me doing that..The head was 325.00..I think the regular price was 500.00 ?..Garages get at least 20% and up off at the dealers..
@@Doulop The relay is in the front in your car. The key is to first check if you are getting 12v at the speakers when you turn on the radio (orange wires). If you're not getting that, your relay connections are bad and not your CDM unit. When you turn on your radio, a 12v signal goes to the relay from the head unit which then turns on the main 12v high current supply to the speakers.
I want to keep my stereo stock too. It sounds and looks surprisingly good. Usually I keep it off though because I'd rather listen to the exhaust. Lol
Yes, exhaust sounds amazing! Wish my radio worked, though. Bummer it don’t! Take care. Have a great weekend!
I feel your pain....my radio started this year....buzzing speaker.
Oh man, that would be super obnoxious. How do you fix that? New speaker, I guess?

Thanks for the laugh with your acrobatics trying to get to that module. Also good job I’m having the same problems.
Haha, thanks. Still haven’t done anymore with it to figure it out. Just wish it worked, haha. Good luck with yours.

Thanks Franklin. Where is the Bose relay located?? That would be awesome!
@@Doulop I saw this in a forum post:
Do the wipers work on the car? On my 1990 (same bose) my cd/cassette used to only display the time. There is a white wire on the CDM tuner that is a source of ignition power and if it isn't present only the clock will display. This wire is tied into the wiper fuse. The radio fuse is only for battery power to the CDM tuner.
There is also a bose power amp relay mounted kinda by the steering column as well as a ground wire kinda right by the place where the door wiring passes through the door jamb.

That sounds like your problem. Also look at wiring diagram:
www.digitalcorvettes.com/threads/radio-wiring-diagram-for-a-1995.250610/
There should be a wire which is only hot when the ignition is on. If you don't find it, that is probably the problem and you have to run a new wire.
Thanks so much!!
Had the hole dash out my 90 to change the blend door motor took the seat out made it a little easier
Yeah, I should do that. Just didn’t feel like doing anything extra. Getting it back in might be a challenge, though! Thanks!
@@Doulop at my age i need to make thing easy
Haha, I’m sure. Would definitely be easier!
My Radio and, cassette works however the CD doesn't. So I use a bluetooth with phone. Couldn't imagine not working at all. Good luck.
Thanks Jeff! If I had just 1 of those work, at this point, I would be happy.
I just installed my bose front unit after removing the working aftermarket one but it doesn’t work either. I’ll check the fuses. The guy that sold it to me didn’t even know if it was working or not. Anyway I’ll keep it like that just for looks
Hey man, sorry to hear this. These old radio’s are very finicky! They looks so nice as stock, though. I like what you did there :) good luck, man!
@@Doulop thanks. I’m waiting for the service manual to arrive and i’ll see what is recommends, probably the cdm is bad. I have the clock when I push the top button but it turns off after a few seconds, the cassette eject makes a sound when pressing the button, the buttons backlight works well, but nothing else, the buttons state leds don’t light up. one thing I could do is to check the harness between the cdm and the head unit but I’ll wait for the manual
Best of luck!
Had a vehicle once without a radio....deff sucks, hope you get it soon! but cool flag!
What’s up Chet?? Yeah, it’s lonely, lol. Thanks man. Love the flag too!
I just purchased a 91 C4, and my stock radio is not working when I cut it on I’m getting a squelching sound coming from the speakers… I feel your pain still searching for a fix… I might be forced to go after market… My antenna is raising up and everything but still no music just squelch! Help! SOS … 😀
Very frustrating, huh? This is my 3rd year without a radio. Wish I knew exactly what the issue was too! Best of luck!
I really enjoyed your vid! I'm on the fence about buying a really nice 96 C4 or 5 to 10k more on a C5. Just curious when the top is on at highway speeds do you get a lot of creeking or flexing noise?
Thank you very much, Rob. Honestly, I hardly ever have my top on at all. When I have had my top on on the highway, the C4 is a very quiet car in the cabin. I don’t recall any creaking or flexing noise whatsoever. When the top is off on the highway, the only noise I can hear is wind noise. When the top is off and you’re driving over potholes and stuff in towns and things, you get a lot of creaking and stuff but it’s an old car, I don’t really expect it not to.
One stupid question. Is the brain getting power at the plug or are you assuming it is? I’ve chased my tail many times forgetting the simple things.
I am terrible at electrical stuff. I put a test light in all 5 of the harnesses that plug into the brain and one of them had the light come on. That’s it. Thoughts?
I’m old school. I use a old analog volt ohm meter. A test light proves you have power, but if you have a bad ground wire you would never know. Just a thought. I ALWAYS check for power and ground before going further.
Do you have any idea where the ground would be for that?
You ever figure this out? Having the same issue on a 1995.
I’m sorry but no. Got frustrated with it so I buttoned everything back up and said forget it. Sorry!
did you check your ground that was my problem on my 91 turquoise corvette
Hi Paul. Where is the ground at that you checked?
@@Doulop the ground is the antenna
Really?? Oh man. I need to check. What do I check, exactly?
@@Doulop connection make sure it's a tight connection
I will. Thanks man!!
I have same problem in My 91
It’s very frustrating. I’m hoping to find a fix this season. Fingers crossed!
My car has had the radio system messed with so I don't know what is wrong with mine.
Sorry, Roy! I know it’s annoying. Maybe someday!
Is Dr. Don still in business?
I do not know. As far as I know he is. I called him last year and talked to him.
Did you ever find the problem, mine did the same thing it turned on for about 30 seconds
Nope, never did any more with it. Don’t have the money to spend on radio issues right now. Sorry man!
@@Doulop I like your video.
Thanks a lot!
My radio works but I'd rather listen to the exhaust .lol
Hahaha!! I have to agree with you!! Happy new year!
Hey man My radio isnt working either, but my radio will light up, I just sent in my cdm to get rebuilt, since you’re didn’t work should I look into replacing my antenna? Thanks!
Hi Reese, my antenna was replaced with a brand new one back in 2014. I don’t think my antenna is bad but I did have a Subscriber tell me that his antenna was loose which was causing a ground connection issue and wouldn’t let the radio come on. He tightened up the antenna and everything worked. I have not gotten my car out of storage yet but I hope to do that soon. Best of luck with your radio, man. It is very frustrating when your radio doesn’t work. Thanks for watching
Man I got the same problem 😕 I don't know what to do.
I know. It sucks.. I wish you the best!
I just picked up a 1990 c4 and my radio doesn’t work.
Sorry to hear that. It’s a bummer. Maybe it’s something simple :(
Hey man I'm looking at a 1990 vette with 61k miles white w/ peanut butter interior for 9,995 there asking. What do you think?
I think that's high. Buy one from someone that has kept the receipts. I personally wouldn't pay 10k. There's a ton of Vette's for sale, take your time. You can get a nice one for 7-8K.
@@shaggywagshaggywag
It's supper mint it's from the dealer If I could send you the link you could see it.
Also I was going with 8k cash on the table maybe they'll let me take it home
@@Jeepfeenz You can post link here in "reply" section.
@@Jeepfeenz Whomever you decide to purchase from, make sure to get a pre-purchase inspection. I guarantee you, it needs some work! After the inspection finds what needs done, you can use that info for bargaining. Or you may want to walk away. Whatever you do, get an inspection!
Is it worth trying to get my factory radio working? or should I just buy a new head unit... i get pretty bad sound from front left, decent sound front right, no sound rear left, and sometimes i get pulsing noises rear right.. I have a feeling it's not speaker related because I tried some known good speakers in the back and didn't have any luck.
Honestly, if you don’t mind going away from the stock look, you will get much better sound, technology and convenience from a new system. I just like the stock look too much to do that, personally. I wish you the best. It’s annoying not having a working radio!
I have a 92 left side speakers don’t work and the antenna works every once in awhile I had the radio rebuilt in 2014 when I got the car thinking about just going aftermarket
Quick question, are the lights supposed to make a clicking noise when you use them
Which lights, Jeff? Headlights, interior lights?
Doulop headlights
Umm, I mean, mine doesn’t make a smooth sound, you hear some noise but actually clicking? Mine doesn’t do that.
Did you get your sound system to work yet. If so do you have a video on it.
I have not. To go further requires money and I don’t have that to put into a radio right now. Big bummer for me. I am sorry I didn’t have a follow up to this yet :(
your seats look awesome. are they aftermarket?
Hi Eric, actually, no. These were the power sports seats that were available that year. The later C4 seats are nasty looking. I am glad mine are what they are! Merry Christmas!
Dude you have any knowledge on headlight switch , 1993 I put a used one in and the dash lights are screwy
Hey Shane, what do you mean the lights are screwy? I recently had my headlight switch out just to clean it but it didn’t fix my problem. My headlights work but my dash lights never come on. Sorry man. Wish I could help :(
There is a module for instruments gauges I find out I’ve ordered one I’ll let you know how it works out ., also if you shine a light in the sensor your dash lights get bright
I’d go to a junk yard and get one out of another corvette to see if it works before spending $225.00. It’d prob cost $59 or less maybe. Idk for sure, just guessing.
Thought about that too, Larry. Will have to see if there are any local junk yards with Corvettes. Thanks man
No corvette junk yards here in michigan
Do you know the part number for the panel you pulled for the CDM?

@@Doulop awesome! Thanks!
You are welcome, Ryan!
When I turn my radio on, the antenna goes up, the screen lights up but if I push a station button, it blows the fuse.
That is crazy! Makes no sense. Make sure you take the radio and the brain in as they require both pieces to work on them! I hope they figure it out for you
I have a 90 6sp vert. My radio has never worked. Can you give me the name/address of the folks who looked at your head unit?

@@Doulop thanks man, best of luck to you as well! One day you’ll get it. I’ll let you know how it goes for me
You are welcome. And thank you as well!
I went to my chev dealer and they put in a new head for 450.00..
What year is yours and when did you do that?
@@Doulop 1994 ..and that was 5 years ago...I got a discount at the parts counter using a friends name using his garage discount then taking it over to the service dept..I know the guys at glenway chev so they have no problem with me doing that..The head was 325.00..I think the regular price was 500.00 ?..Garages get at least 20% and up off at the dealers..
Thanks man. I would love to redo my whole stock system, just can’t afford it at this point. I appreciate the information!
@@Doulop its not as much as you think...Speakers are only 100.00 each...Heres the link to the factory for parts etc.................carstereohelp.com/
Not fixing the problem.
Well, I tried! If you figure yours out, let me know.
Did you ever get your radio working? I discuss radio repair on my video: ruclips.net/video/7I96pXCGsAQ/видео.html See 01:23
Thanks. I watched it. Not sure what relays you are referring to in the trunk. I can’t find anything like that
@@Doulop The relay is in the front in your car. The key is to first check if you are getting 12v at the speakers when you turn on the radio (orange wires). If you're not getting that, your relay connections are bad and not your CDM unit. When you turn on your radio, a 12v signal goes to the relay from the head unit which then turns on the main 12v high current supply to the speakers.
Thanks man! I’ll have to look at doing this at some point. I appreciate your help.
