Hi new to the group, need help please on installing an amp to boost the speakers, found the speaker wires and identified all of them no problem but how/where do I connect the other end of the amp loom to give the amp power/remote switch on. I have 2015 Insignia VX Line Nav 1.6 and the amp I am trying to install is a Pioneer GM-D1004. Any help would be really appretiated . Andy
