Would you agree with Martin as to the performance of your stereo? No hiss at all? Would you care to run any of the little experiments that I listed a few posts back?
Thanks buddy!
Ron
Well, my 8 speaker Premium Bose Sound System has been working flawlessly from day one (October '06). So, as a little background, there hasn't been any reason at all for me to replace my amplifier !! It's still all the original "stuff"....
Now then, after reviewing your post one more time, I went through the list of tests for you, and I have to honestly say that there is absolutely No HISS or any other noise or distraction in my system at all!! You know, in my opinion, both the volume control and sound quality here are every bit as good as any so called upper scale GM radio/sound system I have ever had. FYI.. About 30-40% volume on mine can be very loud..!!
Not wanting to be "puffy" here, but I do have somewhat of a discerning ear when it comes to the quality, clarity, tone, etc. etc. of music & system....So, this Hissing sound thing would drive me absolutely crazy and staight to the GM dealership for sure..!! Some say that enjoying Sound quality and enjoying Music are usually two different goals....
Geeeeee, I sure do miss my full-set of EQ's....
Have a great Easter....
Frank
Now, remember the words of Elmer Fudd here...
BE WERY, WERY CAREFULL......!!!!!!!!
Happy Easter
Frank
PS. Gee, I better say something about my car here or,
i'm in deep ********* Ok...Love my Chevy..!!
The cure I found is to switch on the turn signal for several flashes, and bang it's gone. Since it's so infrequent and I have a cure, I don't want the dealer to mess with it. Any one else have this? Thanks
Frank,
You don't sound "puffy" to me. I would put myself in the same class, as a matter of fact. Now that a few of you are telling me that the Bose system actually SHOULD be a quality system, I will be looking to find an '06 Bose system on the Chevy lot to compare mine with so I might be able to get some warranty work done. Mine definitely doesn't meet the standard of premium. I just wish we lived closer together so we could compare "face to face." But, I do thank you for your help...as usual.
Thanks and I still welcome other '06 Bose owner opinions. The more the merrier! I think we're 2-2, currently.
Ron
P.S. - Frank, one more thing, would you be willing to either take a picture of the amp in your car or give a good physical description? I'll post a picture of mine soon.
1 if your radio appears to be working and the cd tracks
2 if you have no chimes
3 if you have no power to your amp GO TO A SHOP AND HAVE A MECHANIC USE A TEST LIGHT
THIS IS YOUR TROUBLE SPOT
YOU WILL HAVE TO GO TO A BODY SHOP TO GET SOME NEW PLASTIC PINS TO PROPERLY RESET THE CARPET,USE A SHITLOAD OF ELECTRICAL TAPE TO GO OVER THE HARNESS TO KEEP IT DRY AND AS LONG AS YOU HAVE IT OUT CHECK THE GROUND IN THE FOOT WELL OF THE FRONT SEAT FOR CORROSION AS MINE WAS STARTING. I GREASED THAT AS WELL.
Hey Z, by the way,....What year Impala are you working on here...'06/'07 or...???
Anyway, Congratulations on your fix.
Frank
Older theft lock scheme: no VIN data is sent. Owner has to enable this feature and then enter his own security code. And that code is stored locally in radio's computer. As soon as Battery is disconnected from the radio (someone steals the radio and uses it somewhere else), the radio will be locked until the owner enters the correct code. For this type of theft lock, the dealer could also clear it for you for a small fee ($50)
For your 2002 Impala, you could buy an Aftermarket radio and stick in the dash to be done with. This vehicle supplies typical Aftermarket radio with essential signals to make it work (12 V battery, Ignition, Ground, and speaker connections) and forget about the vehicle bus. Circuit City is selling vehicle adapter harness ($15) for all types of vehicle. A decent Japanese radio could be had for less than $200. You probably have to buy antenna adapter too (Circuit City or Radio Shack) since GM radio uses smaller connector vs. typical Motorola type.

I had a car picked out, but when I went to the dealer and told him the one I wanted, he sold it about 2 hours before I got there. The dealer only had one Impala left, and this was during last year's 72-hour sale with 0% financing (around July 4th). So, I took the car that didn't have exactly what I wanted, figuring I'd save the extra money to get what I want later. Am I stuck with what I have, or can I add these things?
I feel like the dealer's giving me the run-around, so I'd like some honest answers and advice.
Thanks!
It is ironic that you state that the 2002 Impala radio can be changed without a problem and the 2006 radio needs the VIN to match among other things that would prohibit someone from doing this.
I have a 2002 Impala and that radio is outstanding, I would not even think of changing it.
My 2006 Impala radio in my 3LT or LT3 however you want to say it, sucks.
I have all options on this car just like the LTZ except the upgraded radio? The 6 speakers are great but the stock radio cannot push them. If I have too much back speaker, I have to literally turn the volume all the way up to maximum to blend the front and rear properly.
I am 55 but I still like to crank it up now and then and the 2006 stock radio is just so limp.
Why would Chevy put all available options in this car and not an upgraded radio, it is beyond my comprehension. I just did not catch it when I got the car.
So you may have a bad BCM unit and I do not know if the problem is software or hardware. If it is software related, then reprogramming the module seems to be a logical choice. If the hardware is bad, replacing module may be the only option. That will set you back $200-$300 for the replacement unit
The second dealer could be right on the bad radio also. If the replacement radio did not do the trick then the first dealer may be right.
There is also a third theory: pinched or intermitten vehicle
bus wire that somehow keeps on disrupting the communication between the radio and the BCM module. In this case, replacing either radio or BCM module would not fix the problem permanently. This theory is only valid as long as the vehicle VIN info is required by the radio
Some newer GM radios need VIN info from vehicle to unlock. That info is from another module outside of the radio. Every time you power up the car, the radio requires VIN info and compared with what it had last time. If the VIN info is not there or incorrect, then radio would lock up. It is their version of theft deterent. Older GM radios requires you to enter a code and that code is stored locally inside the radio. In this case no communication is required with vehicle's module to get VIN number. So consult your vehicle's Owner manual about the radio's theft lock to see if the code is required or not. That will tell you what scheme is being used on your Impala.
Good Luck

So far other than the lousy volume power of the 2006, (with standard radio) both radios are working fine.
I just have to make one comment:
What is wrong with this picture, when GM/Chevy cannot diagnose OR fix their own cars...???????????
Another possibility: if the system has external Audio Amp, that module could be bad.
If there is no Audio Amp, then sometimes short on speaker coil could cause the radio's own Amplifier to shut down. And therefore no Audio
jt
To figure it out, you will need to disconnect one speaker at
the time. If you disconnect the bad speaker from the system, the system should recover (provided its protection work).
If doing so is dificult, you could try to take the entire radio off the dash. You only needs 3 wire to power up the radio: 12V Battery, 12V Ignition and Ground (Ground is tied to metal chassis). So basicall, both 12V Battery and Ignition can be tied together and they are next to each other on the Main power connector. Next step is to find any portable speaker and connect them to at least one pair of Speaker output (Front Right+ and Front Right- for example). You should hear some white noise or even music if you tune to a strong local FM station. You should be able to find the pinout of this radio in some previous posting.

The only other antenna you have is for the remote start feature and that is located on the top of the front wind shield where you see the web like design across the entire top of the glass with a small button located in the drivers side corner.
When and if you replace the wind shield, this needs to be taken into consideration.
As far as installing after market XM, I have no clue but I know others have done this with Sirius radio.
Good Luck.
I have never had a purchased extended Warranty from GM dealers that has not paid for itself, whether the repairs are actual, bogus, or pin the tail on the donkey repairs.
I am not condoning extended warranty's but this seems to be the way dealers operate.
Just a side note:
MY wife lost her key and key fob to our 2002 Impala. (this is not under warranty)
I called my dealer and they quoted me the following:
1 Key fob - $63.00
1 - Key, non chip type - $7.74
Program new key fob - $40.00.
Bottom line approx. $110.00 to replace a lousy key and key fob.............
I went on line and purchased a key fob for less than $28.00 and programmed myself. I did pay $7.74 for the actual key but approx $35.74 is a far cry from $110.00 if I went to the dealer.
For you anti American car buyers the foreign car dealers are no better...................
I have attempted to fix this issue though 2 Chevy dealerships. Each attempt brings no resolution just frustration and them telling me that I’ll just have to deal with it and there is no fix.
This is why I am looking for people with the same problem willing to bring a class action law suit against Chevrolet. All I am after is a replacement radio or a monetary amount to fix the issue myself.
Please contact me via email apetersse@gmail.com if you are interested.

I am sorry that you are having hiss in your Bose system. I have an '06 Impala SS with the Bose system and it has no hiss or distortion or other problems. The sound quality has been truly premium from day one. I am very happy with it.
Has either of the dealers you went to replaced the amp? If not, I would suggest this is a place to start. There must be a solution to your problem but I am not sure a class action suit is it.
Have you had any work done on the stereo in your car? There was a fix for the stereo and I had it performed on my car. While it did improve the problem, it was by no means a real fix. The hiss is still there and the overall sound quality still leaves much to be desired. I actually refrain from listening to much music, especially at higher volume levels because there are certain tones that just seem to resonate through my skull. This doesn't happen with any other stereo, just my "premium" Bose system. I've adjusted my bass, mid, and treble all that I can to try to alleviate the problem but it just doesn't help.
As for a class action suit, it's a great idea in theory but I just don't think there are enough of us. Most of the folks who have shown up on this board either don't have the same problem or don't hear it. The Better Business Bureau may be a better option for us although I've pretty much given up. I will just never buy a Bose product again. Please let us all know if you make any progress.
Thanks,
Ron

Knowing less than nothing about these super sound systems in cars I relied on a couple of my employees who were always installing systems in their, and their friends cars. (Bad move) They told me what to look for in equipment and off I went to the stores. I got speakers and a good amp and some supplies on their list and they were all fired up. A week or so later they still had the car torn apart and nothing was working at all. They had burned up the first amp and I got another on warranty. I realized that they had no clue how to deal with the stock system which I insisted on retaining since the thing programs the whole car!
I finally made them put the thing together so I could take it to a professional shop and it cost me a ton to get it straightened out (suposedly) and it did work pretty well for about two days then one speaker after another quit. I'll not bore you with more details but I decided to try to get it back to the stock system with just some improved speakers (as the originals were destroyed by now) and it was restored by removing the output units needed to bypass the original amp. It worked for a few days then one side of the original amp fried. I called the local Chev store parts and found it cost nearly 400 bucks to replace the stock amp. NO WAY!
So, you guys in Chevyland that know all the good stuff, where should I go from here other than to my nearest Ford dealer? I have checked around for a used amp and had no luck locally. I am soon going to get the car back from my son (and his wife now) and get them into a nice minivan for the new grand daughter. I recently dumped a load into the engine and accessories so I will probably hang onto it because it is such a nice ride for me. I do need sound, if for nothing more than to listen to Rush Linbhaugh on AM.
I'll be listening to your suggestions.
This particular radio can drive 4 Ohm speakers directly since it has internal amplifier. Besides, the original cheapo amplifier is a lousy one so you will not miss it anyway.
At the location of the original amplifier, you basically bypass the amp by connecting its inputs (from radio) to its output (to speakers)
Four pairs of speaker outputs from radio :
1. Left Front +, Left Front - : to Left Front speaker
2. Right Front +, Right Front -: to Right Front speaker
3. Left Rear +, -
4. Right Rear +, -
Each of these wires (on radio side) are has DC voltage on them. They are normally set at 6-7V (1/2 BATTERY voltage). If you have Voltmeter, you should be able to double check.
To check if radio internal amplifier is OK: Since I do not know the physical connection at the external amp, my info is generic only.Amplifier box typically has inputs from radio and output (to speakers) located in the same connector. So you need to go to Chevy dealership to ask for help (electrical pin-out). This is available in their Electrical diagram
Here are basic steps
1. Turn radio on
2. Find the Left Front + and Left Front - pins (from radio).
3. Connecting each pin with each pin of speaker (known good one). If you hear sound , that radio speaker driver is OK.
4.Repeat Step 2-3 again for the remaining driver pairs
The above steps are to confirm that your radio internal amplifier is not dead yet.
After that, just connect these pairs to the corresponding vehicle speakers directly. Again the connections to the vehicle speakers are at the connector. If you suspect original speakers are bad, disconnect them, then try one at the time. Note that two terminals of each speaker must not short together. If that happens for long, the radio amplifier drivers will be damaged. Bad blown speakers could have their terminal shorted (causing radio amplifier to shut down or burn up) or open (no sound)
So basically, you need to get the electrical pin-out of the external amplifier's connector(s) for this experiment. Some people in this forum may be able to help. If not, stop by a Chevy dealer and ask them. From there, you could do your own experiment and save you $400
Another way: stop by a junk yard and they may sell you an used one for a lot less. Make sure they can let you return if it is not working.
Good luck

One bright side to your story, though. You DON'T have to listen to Rush in the interim. :P Sorry...couldn't resist!
I decided, after owning my 2004 Impala, for the past three years, to finally upgrade to a touch screen.
I heard through a customer in my store that the chevys have something called an information module/system that hooks into the factory radio. it basically controls the on-board monitor system/light in your dash about your oil/tire pressure/etc.
after the guy installed the new system and amplifier, all of my speakers in the car died. the customer, who had been through a similiar issue with his malibu, told me i have to find an aftermarket information module so i can access my car's electronic functions.
has anyone gone through this? and if so, did you you have to buy the aftermarket module, how much and from where?
any information would be greatly appreciated. thank you
