My head unit is a Kenwood KDC-BT42U and ive been given some 6x9s for the back which i have installed. I have wired them from the speakers to the connection on the back of the head unit but they dont work at all. Im assuming its + to + and - to -??

Sorry mate, you've lost me here.
Yes it should be + to + & - to - but what are the pictures showing us?
You haven't connected anything in the pictures so I don't really know what you're asking.

Just a quick and obvious question - the fader isn't just set to front on the head unit is it?

From the looks of your ISO (connection blocks), whatever you end up with, it's probably gonna be messy and a fire risk! it's a right mess!! If you dont intend on buying a new one (£17ish which I would reccommend), please make sure you reconnect the cut wires using suitable electrical connectors or there's a posiblity you will be one day be listening to "great balls of fire" and end up in a great big ball of fire!

start from scratch if I were you. If you dont have an external Amp (big metal thing in the boot) it should be fairly simple (bit like hooking up a stereo system). The speakers are the simplest thing of an install. The wire should already in place from the standard speakers but it looks like it's gonna be difficult to tell which one is which now as they've all been cut from the block.

So, if you've already screwed the new speakers into the doors, you then need to find where these wire are (stereo end) and label them (this will pay dividends next time you come to to them) then follow the above post to re-connect to the ISO block. Now, because all the wires have been cut, then you need to check the "connections" part of your Kenwood manual to see where these wires (the stripy ones) connect the rest of the ISO.

I don't fancy the job myself, buy a new ISO!
