first us see what is your requirment and what you require....
from the above specs sheet we can see that the 1.400 requires 55 amps when wired at 1 ohms and the 4.300 requires 16.5 amps only....these are the max musical power demands if sine waves are played the amperes will increase more so a little more thick wire will be fine....

from the above chart we can see that these are the normal current carring capacity of a wire or we can say max a wire can take so always take a upsize...so we can take a upsize ...
for the 1.400 we can take gauge 8 cable or 4 will be more than sufficent and will be more than extra for the purpose...but I will recommend 4 gauge....
for the 4.300 we can take a 8 gauge for the job even if you use a 2 ohms speaker or a 4 ohms one.....
I would suggest drop the distribution block idea as it will require a good expert to do it and more joints will be there in the path....
for your job take two wire put the fuses in the engine bay and run the two wires where the amps are going to be mounted.....connect the main positive directly to the amp and ground the amp with a soild earth point like the seat belt bolt which is directly goes into the car chassis....
for the speaker wires and rca leads you can get them easily as they dont make a major amount.....
for the power wire you can use finolex as they come in mmsq size you can consider 16 mmsq or 25 mmsq for the 1.400 and 10 mmsq for the 4.300...
for more good option you can go for LAPP cable they are German product used in merc car wireing....the LAPP cable is about 40 % cosltier than the regular finolex cable....
the finolex 10mmsq one meter is for approx 60-70 rupess and the lapp would be approx 90 -100 rupes...the 16mmsq and the 25 mmsq prices I dont remember but would be in the range of 125 and 175 respectively....
for the termination you can get good thimbles made out of Oxgen free copper terminals made by Jainson avalable at any good electrical shop....they would avalable in ring-type, u-type, pin type....use the appropiate at the place required...like the ring type for connection at the battery terminal and the pin type for the ampilfier connection..here is a pic for the reference....
