Got hold of a standard sub, ready to go in but alas no luck, any help, please!

Okay so I recent had a thread explaining my sub was missing.

 

Couldn't be bothered with the fuss of fitting an aftermarket one so went standard (thanks octet)

 

Now, I expected to get it and just plug it in but the mess of the wiring isn't allowing me to do so.

 

Does anyone have any ideas? If not, where could I go to get the mess sorted out?

 

Here's some pics of my dilemma!
