Overloads with volume a third od the way up,i have 2 12 inch cerwin vegas hooked to it
There is not much info in your question to properly answer it but here are a few things.
1) The VSX-D307 is a home receiver that is rated for no less than a 4 ohm load. If you have two 12" 4 ohm CV subs on the same channel and they are in parallel, that would create a 1.7 ohm load which would easily cause the problem.
2) If you have one on each channel connected along with speakers that are for you mids and highs, the way they are connected could be reducing the resistance load the amp will see which would easily cause the problem.
3) If you have one on each channel and no other speakers the problem would be simply that your speakers can use more power than the amp can produce. Thus you are able to raise the volume of the amp passed it's maximum output which would cause the amp to clip and the amp will go into overload protection.
4) Your receiver has an 8 ohm rated amp. Which means it can run at 4 ohms but the amp will produce more power at lower volumes on the knob setting and will max out at lower levels than if you were using a 8 ohm speakers.
In short, CV's can use a lot of power and your receiver, regardless of advertised power levels, cannot give the speakers what you are looking for in sound levels. Buy a larger dedicated amp for the CV's as the clipping from your Pioneer receiver is doing damage to your CV's. Your speaker's can hear the clipping before your ears can so damage will start to occur before your ears can hear the clipping.
