I’m a novice with wiring and electrical stuff so any help would be appreciated. Here is my planned system:
Don’t laff at the drawing!! Hahaha 
Is the rca bit correct for the amp? Do u get a distributor block like for the battery or do u run two rca’s???? I aint got a clue! Can sum1 edit the pic to show me how I will wire in the 2subs and what ohm they will be showing?
I was wondering what guage wiring I’d need for all the wires? Don’t worry about any earthing bits but what gauges?
This is the specs for everything:

get big power wires 4 or 8 gauge
you can get split rca leads that go from 4 to 2 to hook up your rca's ( there is no distributor block for rca's) but you can get headunits with 2 or more rca inputs so you could run both to a headunit.
Also get some good thick speaker wire and make sure battery and connections are all good. U2u me for more info / help

cheers corsa_sri04, thats a great help, got a picture now of how it should all be set up!
how can i ensure my subs are showing a 2ohm load? does any1 know how this should be wired using my above diagram of the + & - on the subs and monoblok amp. my subs are going to be on either side of the boot so in diff boxes so ill therefore have 2 seprate connectors.

2 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 6 Ohms
Dual-4 Ohm Subwoofer: 4 Ohms
Dual-2 Ohm Subwoofer: 2 Ohms
