So its the factory amp thats causing all my problems then? Is it because my HU's amp is sending power to the factory amp? If thats it I'd like to just ditch my factory amp altogether. You said theres a bypass plug, where can I get one at for my car? But you still say hooking all the amp power and grounds blue & blue/white wires to power wires will get rid of the problem? I already hooked the blue/white ones from both harnesses together and it made the internal amp work. Should I take them apart and hook them to the red one then? Sorry for all the questions, but thanks for the help.
