Ok, I just picked up my MDX from the installers. They put a fiberglass enclosure in the factory sub location. My question is, he took out the little stock amp for the stock sub and just left it out. Now, when I got home and hooked up my JL 300/4, my radio would not turn on. It is an aftermarket Eclipse 7002. Could unhooking the stock sub amp have caused this? Does it have any kind of power connection that would keep the head unit from working? I hooked the Eclipse up with a standard Honda wiring harness. Any thoughts or is it just maybe coincidence. I am not sure where to start.
