Hello. I have a sub with amp screwed to it in my old car, which I'm thinking of transferring to my B5 avant but would like it to be removable because the dog lives in the back sometimes. Does anyone have any suggestions on how to go about it? I'm thinking of wiring the two power leads up with a 2-pole speakon joint and the remaining phono and remote lead with a 3-pole XLR. All routed through the cd changer hatch to the front of the car. Or do I make the amp permanent somewhere and just run a speakon lead to the boot for the sub. Any thoughts?
