Re: stereo loses power when vehicle is in motion.
Look for a loose wire or connection! Obviously something is getting disturbed by the bumps and motion of the vehicle.
You would have to get access to the wiring that is associated with the radio, and try moving, pushing, and pulling on the wires and connectors to make some kind of disturbance. They when you make the fault, you work your way around to zero in on the exact location.

It's not the receiver, it's the interface. If you recently had this unit installed with a door chime or, some other type of LAN data interface to replace the door chimes, the adjustment is off. The interface/door chime needs to accessed to turn the volume down. The interface is neccessary because when you remove the factory stereo from a newer GM vehicle you lose the door chimes, accessory 12 volt power source, ON Star, etc. The LAN data interface replaces these features when adding an aftermarket stereo.
I'd say go back to the guy who installed and get him to do it right. He's either left some wires exposed so they are intermittently touching, or has an open connection to one of the speakers. The amp will shut down to protect itself. He may also not have wired the speakers correctly. Some systems don't work unless both hot and ground wires run directly to each speaker. Some installers run only a hot line and use the car body for ground. At higher powers this can cause amp shutdown or keep it from working at all. In any case the installation wasn't done correctly.
mine does this too, I have the deck on my boat and on land the deck cuts out when a bass line hits or loud music comes in, cuts out at about 20 on the volume level, however, when on the water and the motor is running, my voltage is up to 14 vdc or so.. At this point, I can crank the deck up to 30-37, and it will scream , doesnt cut out or lose power just rocks. I have heard that kenwood decks are competition stereos and require 14-16vdc, but I have never found any proof of this. One thing you can do is order a battery from summitracing.com that runs higher than 12vdc. But then again im just speculating
Same problem as yours with my deck. Bought the deck a month ago, turned car on in the morning face plate does not move down, music plays everything ok but can not access the cd or move the plate regadless button pushing. Have you tried the reset button? Hold it for 3 seconds ( ball point pen to press the button above power button) U will lose the presets but Oh weel. I am going to remove power completey from the unit later on today, and if it still has issues I am returning it for a replacement ( Bought it form Best Buy) L8R
You are using an amplifier in this vehicle. There are two "Blue" wires on the back of the stereo. One, antenna, supplies power to the power antenna during radio mode only and the AMP trigger supplying power to the amplifier in every mode. You chose the antenna wire to power your amplifier.
i have alpine stereo's in all my vehicles and i have had this problem. if you run a 10-14 gauge constant wire from the stereo directly to the battery the stereo will not shut down in protection mode. it is not the cd it is the stereo going into protection mode because of lack of current not voltage. i hope this helps after i did this i could play the stereo as loud as it can go until my battery died
I fixed the sound problem with tech support from Kenwood. I had the blue wire from the Kenwood which is the antennae turn on wired to the amp turn on for the vehicle (2001 Blazer with Bose factory stereo). This is how I was told to wire it from the installation tech where I purchased the wiring harness. The tuning played fine because the Bose amp turned on when I played the tuner but when I played the cd or aux the amp turned off, thus no sound. The kenwood tech toldd me to wire the blue/white wire to the amp turn on for the vehicle so the amp would be on when ever power to the Kenwood was on. I rewired this way and everything works great now.
