I have a Sony CA700X headunit, it's really old. I had it for my old car for 2 years and then this car for another almost 2 years now. I've finally ran into my first problem with it though, my subs. I installed my subs the other day and everything works fine and dandy until I go to play a CD. The power to my amp and subs shut off when I switch modes to play a CD. So the only time the subs punch are on the radio. Is my HU too old or am I not hooking it up right? Here is a link to the HU, one on eBay atleast.
