whenver possible, i would run single large gauge back, and then distribute to the amps.
reasons are plenty.
1. cheaper
2. less chance of a wire being cutt
3. less holes in the firewall
4. easy to do single fuse / CB upfront so you can instantly cut power to everything int he back
there have been cases where i have ran two 4 guage instead of a single 0, mainly beucase hte car has very thin door sill area not conducive to 0.
btw, you should consider just doing a single 0 instead of 2, if you are going wtih a signle run, why not be safe and just do a 0?
