Electrical Questions / Wiring

Hey im looking to run my new electrical system next month and I just want to make sure I have everything im going to need to run it properly, Im hoping to run a newer sound system in the car something like 2x110 RMS at 2ohm, 2x100 RMS at 4ohm and a 2x 10in Sub with 300 RMS each at 4ohm with a final impedance of 1ohm, I got a 4500w 5 Channel. D series Amp and the alternator upgrade im putting in will be 140amps will it be enough to run this system, I have a decent battery something like 130min 950 cold crank only 5 months old. What types of wires should I run also with the MAD electrical work around can I still use the Big Three upgrade?, as well as any tips for running the wires should I put fuses in what parts should I need?, the engine harness is being changed to one that will support an Electronic Ignition, don't know if that will affect anything. any help or questions to explain anything more are always welcome thanks guys
