[QUOTE="BobTheSlob, post: 246886, member: 547470"] After countless weeks of testing everything I could do by myself, I went to my friend's house. He recently ripped apart his system, so we had parts to spare. I put my sub box in his trunk, and tested the sub. Perfect. So, since we knew his amp worked with my sub, we put my sub box back in my car along with his amp. We plugged the Power, Ground, and Remote wire ONLY into his amp first. It powered on. It was glorious. But, then we plugged in my RCA cables. Before I go on, I would like to list what I have read for voltages in my car Battery gives ~14.4V while the car is on. My power wire reads ~14.4V while the car ison. My remote wire reads ~14.4V while the car is on. My GROUND wire reads ~60mV while the car is on. 60mV is pretty low. That's ok right? Now, the RCA cables. I tested the voltage by testing the metal sleeve around the plug. It reads ~14.4V while the car is on. When we plugged the RCA cables into his amp, it did the same thing mine does. It shut off. Now, my amp's manual says that if the RCA cables are sending DC voltage, which they are, then the Diagnostic light will come on, which it does. My RCA cables are sending ~14.4V of DC current to my amp. Why is this happening, and how can I stop it? [/QUOTE]
