My question is about wrapping my positive wire through mix31 core only. as i have always been told that my negative wire should go to a chassis ground as close to the equipment as possible. this is for a mobile install .. currently my install is as follow radio positive fused and wrapped through a mix 31 core around 9 times by battery positive post.. negative wire to chassis ground next to or as close as possible to radio and then a 1-inch tin copper braid from radio case to chassis. 10-gauge wire is used as positive and negative wires also have an amp that is basically connected the same way and my antenna switch just has a 1 inch tin copper braid to chassis is the correct way?

For keeping RF off power cables you would wrap both the + and - wires through the same core then ground the - at an appropriate point close by. Otherwise you defeat the purpose of filtering your power lead(s).
thank, great information thanks for pointing me in a direction where i can learn and not just answers
thank you, after reading a bit more. i will get positive and negative wires twist them and wrap through the cores then ground to chassis and run positive to equipment

Don't need to twist them but they look nicer when wrapped around the core in parallel like it was two conductor speaker wire.
In the case of blocking rf or noise from a dc line via a ferrite core you want as many turns as will fit.
