Hi Guys

Could really do with some help here please, as I'm insisting i install my own sub whilst i have time off from work.

I have a monoblock amp
Sub
And amp wiring kit

I've looked at Andy macs guide to installing an aftermarket sub with an amp but i don't quite understand it.

I want to maintain use of my rear speakers off the stock amp, and run a signal to my amp for my sub.

Can anyone clearly explain how i tap into my rear harness to do this??

Any extra parts that I'll need to buy? Do I need to use a line level converter? Is there an adapter I could buy to save me cutting the loom? I've attached a picture of the plug I'll be tapping into, just not sure how to go about it...
