i know i had to screw the heating switches back onto the fascia before i could attach the wires but then when i attched the switches i couldent get my hand behind the fascia to push the things in, and i was thinking how the hell do they put these together in the first place but did it in the end and come out with loads of scratches on my wrist lol but worth it because the sound is so much better now with a sub and amp, thanks again mate
