Sometimes s*** like that is the best method to just get it working. When I try to be perfect (I don't do it often), and stuff starts going wrong, I spend so much time on a small step like this, then when the next issue comes up, I just give up and walk away.
This weekend, I was relocating my sub from under the seat to the QPM and made a few similar wiring compromises.

I have no doubt they'll hold up for a long time but if they don't I just lose a subwoofer so not really critical. I really need to dig in to my antenna not working too. I have an extra one and need to bench test it and see if I just should replace it.
