Hello,
I was amazed that my 10" sub box and amp fitted in the boot of my 2004 04 Cooper, but now I'm wondering if there is an amp wiring guide anywhere? I've had a good search but can't find one.
I have done this before in a few cars, but everytime I've struggled to find the best route to the battery (apart from my BMW where the battery was in the boot!

)
Any guidance or links about running the power and RCA cables and earthing points would be gratefully received!
Cheers.
