I have two type R 12" subs that are 4 ohm dual voice coil. I have my subs wired down to 2 ohms since they're dvc. They aren't seized or blown I've done the battery test multiple times. I also have a hifonics Brutus BRX 2000.1D amp. Recently I was having grounding issues in the cab of my truck but it was quickly resolved with a connector from the battery to a under the hood cab bolt. My amp is getting power and my speakers are connected the way it shows me to in the diagram but they still will not move. I have checked to ensure my RCA's are in the correct subwoofer ports in the back of my pioneer stereo numerous times. I have also made sure that my subwoofers are turned on in my stereos settings. I have been dealing with this issue for a couple of months now. I have reached the point of much frustration and any advice would be helpful. P.S. I have not tuned my amp and I also have a multimeter.
