what wir should i use for this ground

[michigancapri92]

ok so i have a bolt going through a wall to go to my amplifier grounds could i run 2 4ga grounds to both amps to the bolt and then 1 4ga ground to the ground ?? or should i get a 0ga for the other side of the bolt ??? the amps are p400-4 and p300-1 so not a huge amount of wattage going through but would like to make sure before i solder all the connections.

You're fine using 4 gauge. As long as the connections are secured, I wouldn't worry about it. I see groung noise in your future though, just because of the nature of what you're trying to do, but maybe not.

why and how do you see ground noise in the future ?

Because generally you want your ground to be short and to the point. Not attach to a bolt here and there, solder there, widn there, crip here, there everywhere. lol. It might not though.

well it will be about 4 inches from bolt to amp then 6 or 7 inches from bolt to car ground ... all connections are soldered and bolt washers nut all copper all high quality Rockford Fosgate 4AWG OFC wire it would be that or i would use a distribution block to go from 2 to one so they both seem like the same.
