[QUOTE="shivr, post: 8302645, member: 662573"] The sub just stopped working randomly when I went to start my car, then the next morning I started my car and the sub worked again and I went to double test and turned my car off and turned it back on again and the sub no longer worked and hasn't worked since then. I spent hours testing everything so I'll list everything I done and see if anyone can see something I'm missing, or confirm what the problem is, I suspect the SW output is dead on my headunit. AMP is brand new MB Quart FX Series 700W - Confirmed working. Sub has been tested in a different car with a different amp and worked. I am using a Kenwood deck - not sure what model but its 2-3 years old. I tested power cable to amp getting 12.3, Remote wire 12.3, ground is good, checked all fuses and they seem fine. I've checked the wiring at the harness and redid ALL the wiring and everything is perfect. I tested the RCA cables and they work, I figure the SW preamp on my deck is broken, but it's still putting out voltage, is that possible? I was testing on DC the 2000m setting it was getting 90~ on low and 120~ when I had the volume turned up. So in summary, I've tested every single cable and they all are getting power. I've checked my wiring with the harness and everything is connected. I've checked every fuse. I've checked the subwoofer. [/QUOTE]
