System setup- wiring/distribution blocks

[wfofl3425]

Ok, whats up? Im brand new to the site so forgive me if I ask repetitive questions. While Im not new to installing sound systems, I am a bit out of date. I have watched numerous SMD vids. I notice sometimes he uses his ring terminal distribution/ground blocks and sometimes he uses the push-in wire/allen wrench securement blocks. Is there any more of a benefit from one to the other? Im your typical, middle class, blue-collar working family man with a wife and three kids so I dont have money just to burn. Any help in leading me in the right direction would be very much appreciated. I will be running a Rockford Prime R300-4 and a Skar RP1200.1D. Thanks again

I've also noticed sometimes he uses one fuse by the battery to his distribution block. Then another time he used his double anl fuse block up front to his distribution block in the rear. Btw, I will be using 1/0 main power cable.
