Basically, I installed subs and they work perfectly fine when I don't connect the factory amp wire as i call it or the 2 blue wires that turn on the door speakers. they work only if i don't touch the volume and if I do I have to disconnect the indoor speakers and turn the sub up with music on then connect them and turn the radio up. other then that I have them connected and the subs won't turn up or something I'm getting enough power because they work fine when I don't turn the volume up. I have an aftermarket head unit and I also tried fuse tapping the REM to the fuse box and keep those 2 blue wires that turn on my door speakers and it still just goes out when i try to turn it down or up.. this is really irritating me please help
