So I just bought a MINT 04 C5 with a Bose system, I believe it's all stock.
Anyway, car's fine except today I noticed the stereo went into "muffled" mode. That's about the only way I know to describe it.
So normally you hear bass, mid and treble. And all of a sudden it was like the treble disappeared and a lot of the mid range went away too so all you're left with is some strange bass with a few mids thrown in for sound.
It seems to come back after 5-10 minutes. I dunno it's just weird and has me a little shaky since it's a new car.
It's only got 8000 miles on it so I suspect it's been sitting in some garage for a while.
Any known issues with these Bose systems I should know about? Any recommendations on where and how to even begin to fix this?
(This is my first Vette so forgive me if I'm asking a n00b question please)
Much appreciate the assistance on this. I'll probably end up having to have my dad or uncle who are do it yourself type guys take a look at this before I swallow my pride and take it to a dealer or something.
If I start taking it apart I'll never get it back together.
Much appreciate the help here. I'll check out the FAQ, I glanced at it but haven't really gone through it in detail (yet).
I'm bookmarking the disassembly site too cause that'll help whoever eventually decides to help with this.
My gut tells me that this car having only 8000 miles on it in 6 years means it sat somewhere and wasn't used and this thing just has "I haven't been used in a while syndrome" or something is loose. Leaning toward a wire or something being loose but that's just a feeling. I'm a computer guy, not really a car guy unfortunately.
Hey at least I'm not the middle aged guy that bought his first vette! I'm still only 26
Cool. Just keep in mind, alot of Vettes are low mile cars, mine has 1800 miles on it. One of the first things I did was a stereo removal and reinstall, just didn't like the OE setup, plus I wanted a ipod interface so it is worth checking out.
Just follow that how-to and you can't get in too much trouble.
Yea, honestly I'll probably get a new head unit anyway with an auxiliary input cause I don't really like the iPod accessories that use the radio or whatever. Direct is the way to go.
I figure I can have the audio chick at the local best buy take a look or whatever.
Yea I think you're right Hawk on the Best Buy deal. I had her install something simple on a chevy pickup. I was slightly kidding.
From now on, I will only talk serious about vettes
Bongo972,
Putting a LOL or kind of takes the edge off of the post. Just offering a suggestion. Like most of the buds on these forums, I worked hard for a long time before I could buy one. Putting kids through schools; paying for repairs and all the other things life throws at you, put a delay in my plans along the way. We are all happy for you to enjoy this great beast at such a young age. Personally, I am like you - a non-DIY guy. I hope you appreciate what you have my young friend.
The C5 radio schematics are available here if you need them.
In C5 the radio has an internal amp that powers the four mid/high range speakers, but not until after the line-level signal goes through the Bose sound processor. The Bose processor splits the low frequency signal and sends it to the self powered subs in the doors.
Since your door subs are still working, I'd have to guess the amp inside the radio is going out, the Bose signal processor is going out, or if you're lucky you just have a loose wire or plug somewhere between the radio and processor.
Please let us know what the problem was if you figure it out
Mark I think you're probably right. I'm thinking bad stereo at this point. Guess I'll check with the chevy dealer and get a quote on a replacement of the stock one.
I always get scared anytime someone is going to monkey around behind the dash
As we talked about in the other thread in General section good place to start;
"Ok, so the first thing I would do is pull the radio surround and check the connection. The car has low miles but you never know if an aftermarket radio was installed without looking, as I have done in my car.
You will have to take off the armrest, about four screws and then remove about four more screws from the radio surround, then pull the surround off, it uses clips to hold in place. Next a few screws holding the radio in place then slid the radio out and inspect. I'm not certain on the number of screws but its not all that hard or that many, I'll look for a how-to.
Corvette radio systems have a amp for the bass in the doors that is remotely located, I don't know where, and a amp in the H/U for mids and highs. So once you find out if all is stock and you have good connections this would be the next place I would look too."
If you then decide that the H/U needs replaced you can check the for sale section and see if you can get one there. I looked and there are some options, one for like $100 bucks, can't hurt to look.
Thx man. I think you hit it with the amp that does the mid and treb. I'll look for a new stock bose H/U.
Me again
I would NEVER spend money on buying another stock radio when you can have a zillion more features with a new one (BT, iPod, GPS, Movies, etc.). Just my 2¢
Good point. What's your favorite H/U (I've always heard Kenwood is real good for consumer stuff) that doesn't cost an arm and a leg? I don't mind spending $100 or $150 but once they start getting into the $500-$600 range it makes me want to cry.
All I really do is listen to the radio and plug-in my iPhone occasionally.

But if your budget is tight you may want to pick up a used stock H/U for the time. You will need an interface for an aftermarket unit plus the H/U so I don't know if $100 - $150 will do it. Someone will chime in I'm sure that will know. I did a complete system so I don't know anything about the interface hookups.
The search feature is your friend also when looking for more information.
