1/0 Rockford Fosgate Power wire and 1/0 Ground wire okay?

i doubt it was solely because of that. i had issues grounding places other than directly to the battery. most noise is introduced thru the RCAs. and those god awful pioneer decks //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

I have Pioneer AVIC N3; it doesn't have rca's built-in to the deck like pics I've seen on here where RCAs need to be grounded but, instead has an plug with the 3 RCA outputs. Anyone heard of have experience with the Pioneer Nav units?

Is it okay if fuse 1/0 power wire from rear battery to distro-block to 2 amps? Or I am just better off looking for a fused distro block?
