Stereo power problems after installing aftermarket JVC Stereo
I did a quick search and did not find the information I was looking for so if it is out there, I'm sorry for double posting.
This weekend I installed a JVC KD-S100 head unit using the installation hardware received with the order from Crutchfield, including the necessary PAC adapter.
After the installation, the system sounds great until I turn up the volume and the stereo turns off and then back on. I called Crutchfield and they suspected it was a problem getting enough power to the stereo when I turn it up. I re-checked the wiring, switched from my "twisting" method of connecting to using wire connectors and I still have the problem. I know I am getting over 14v constant through the yellow wire and through the red (acc) wire I was getting around 13.2-13.5v. If that is the issue, any tips or tricks that I can use to get a more constant level of voltage to the head unit?
Any advice or comments will be greatly appreciated.

run a wire from the positive wire on the ciggy lighter to the 12v ign. wire on the stereo, check 12v and ground connections, and try it again. If you still have an issue, there could be a problem with the radio. What you are describing sounds like the radio is starving for power. You may have heard someone refer to an amp as "clipping", which is a similar problem.

Thankfully I ordered from Crutchfield because the JVC customer service is lacking or non-existent.
I took the voltmeter out and checked the voltage while the stereo was on. When down at a lower volume, the voltage was a constant 13.5V, but when I turned it up and adjusted the EQ, the voltage was all over the place jumping from 13.5 to 7 and lower and then it would turn itself off. According to the Crutchfield rep, the PAC adapter has a 1 amp draw limit on the acc wire, but some stereos will pull more than that amount from the wire which can cause the stereo to turn off. They are sending me (for free) a relay to wire into the system. Hopefully this will take care of the problem.
