Thanks for that mate, I'm too stupid to work that out though. I was thinking of just getting 0AWG as its 1500RMS @2ohms, but when I look for the cable, the only packs I can get are for 2-4 Amp connections
EDIT: Then I realise you can get the cables seperately, I think it's best to ignore my posts for at least 3 minutes, because I'll just figure it out
Ok so 1500RMS RMS into 2ohms
approx 750W RMS into 4ohms???
Multiply by 2 and divide by 13 = 115Amps
look on the table and for any length of cable (battery to boot we're talking here) greater than 3.3m you need 53mm2 cable which = 0 Gauge.
Not that hard
Figure may vary depending on the RMS of you amp into 4ohm.
Have a talk to some decent local dealers. You will probably find a better deal with better quality (higher copper content) cable than buying a kit from the likes of CAD or CAS.
This is a list of recommended dealers......

I got a great deal from MegaWatt in Runcorn on some Audison Connections Cables, very good prices and top quality stuff.
