Thanks, I was definitely worried about the wiring from the head unit to the amp, but it makes sense to go around the front if possible. I think new speaker wire will be the best bet too, I don't think it is too expensive, just hoping it isn't a pain to push the wire around everywhere. I will have to draw up a diagram to make sure I understand all of the wiring. TBH I have never even seen an amp in real life. I'd prefer to probably just buy a prefab box to save the hassle of figuring out exactly how it needs to be made.
