Grounding a Relay

[chibahawk 10+ year member]

Okay, I'm probably going to use some cheap-o 18 or 16awg wire for my relay and PC fans which will cool off my amp... just wondering though, I'm going to be using a Distro Block that is already accepting two 4awg wires and outputting one 0/1awg wire to the chassis.... would it be possible to just jam the smaller ground wire into the block or something like that?

Also I have an inline fuse holder with this wire.. any sense in fusing the ground for the REM turn on or is that being over protective? I'm going to be running 4 PC fans, 2 80mm and 2 120mm... and maybe some LEDs in the future

You can just ground the relay to any metal grounding point. Just a terminal and a screw. You don't need to fuse the ground, but you should ground the 12V constant feeding the realy with a 1-5A fuse, just to protect the wire "just in case."

yea but the way my amp rack is going to run... itll be easier to just run the ground wire to the d. block and keep all my wires together... would it be possible?

Yeah, you could do that, just as long as that is your ground d block.
