Ha ha cool....... I've made that mistake before with a switch.. Have you switch the sub because you couldn't be bothered to wire up the remote wire? 
Partly

I did wire up the remote wire but it was a dodgy connection so the sub was flicking on/off, but also partly because the g/f. I think her words were something along the line of 'don't get me wrong, I like the seat vibrating, just not all the time'

So all in all it seemed like a good idea to just wire in a switch, simple and effective
