I am running 2/0 welding cable from the remote rectifier to my 8 L16's. From the Niehoff, three 4 gauge cables from the alternator stator studs to the remore rectifier. Get this, the remote rectifier consists of 3 positive and 3 negative 1,200 amp 1,625 PIV rectifiers. The anodized copper heatsink material (1/4" 12" X 16" plates would have cost me a fortune at today's copper prices. Top charging and checking those batteries is a pain of accessing but it has to be done. Rolls makes nice L-16's :)
Quicksilver started out looking like this...
