Stereo
I had a new Kenwood stereo installed in my 08 C6 about 2 years ago. Its fine until recently whenever I hit a bump the volume increases after a little static.
The Tech at Best Buy where I bought the stereo said the old Bose amp is most likely the problem and should be replaced. He said it should be replaced with only a Bose amp.
Any comments ? And where would I look for one beside GM parts ?
Thanks for suggestions

I think the Best Buy tech is just guessing here, it could be a number of different things such as the head unit going bad (fairly unlikely), it could be a bad interface (been known to happen), but it could be the amp (again, fairly unlikely). I suggest if you're unable to trouble shoot it yourself, you take it to a reputable stereo shop in your area (other than Best Buy) that would be able to troubleshoot your system for you. Keep in mind that Best Buy isn't all knowing, and that they hire a lot of inexperienced people. Do you know by chance which interface you're using ?

I agree with MadsonP. My guess is, it's most likely something with the wiring connections behind the head unit and maybe with the wiring harness interface. To the OP, if hitting a bump causes static, that sounds like a loose connection and your most likely culprit is what I mentioned. Best bet is to pull the head unit out and check the plugs that go into the interface. You may need to replace the interface box if it is not holding the plug securely enough to hold the connections, which is known to happen. Replacing the amp or head unit sounds like a wild goose chase. Start with the simplest, and most likely, fix first.

Was it doing it before? If not, it's likely the interface. The interfaces are less well made than you'd expect for their price, and it's not uncommon to find cold solder joints or similar issues with them.
It's pretty odd, does the volume keep going up, or does it just go up for a second and then go back to normal?
Side note, good luck finding an expert. The days of car audio being big are long over. Most independent shops hire the people that can't pass best buy's drug tests. There's a handful of guys around the country that still are good and in the business, but most everyone saw the writing on the wall and transitioned to new fields. It's not kike the 90s or 00s anymore where you could have a few good guys all making a living anymore. You have to either deal with money is no object guys that you can overcharge for everything amd do nothing less than a 5k build, or you try to go cheap and do a high volume of easy stuff with inexpensive labor.

If I were to replace the original Bose amp, where is it ? I was told it is in the back of the car somewhere, and should only be replaced with exactly the same model number.

It's next to the fuse box under the passenger side floor board. If you do end up getting one, look for one in the C6 Parts For Sale/Wanted section of the forum, you can find them there pretty cheap.
