I've finally bought all the items I need, which are a MBQuart DHC254 sub, Genesis Profile Sub amp (secondhand no instructions) and a Autoleads Q-DOS competition pro QAWK4 gauge wiring kit. I was hoping that the wiring kit would have instructions in it but it doesn't .

I'm no electrician but how do I wire up my sub and amp . My headunit is a Alpine CDA 9856R and the car is a 05 STI Impreza.

Any help or links to help would be tops.

Or would I be better getting an expert to fit and set it all up?

Thanks, Wolfie.
