I purchased the metra llc1 loc from autozone. I am installing it in a 2019 ford fiesta. I tapped into the right rear speaker wires and tied the left and right positive to the positive speaker wires, and tied the left and right negative to the negative speaker wire. Then ran the rca’s to the mono amp. I have tried adjusting the level output screws on the LOC, but when I turn the stereo up to half volume, the subwoofer cuts off, stereo keeps playing. I also have to fade almost all the way to the front to keep it from cutting out. Any suggestions?
