New LS install. Quick newbie question

[kybluediver]

I've searched and searched and i understand the LS is a battery hog and needs some heavy wiring. The unit I am replacing already has a 10/2 from there straight to the battery. I have added a on/off switch to this wire as well. Here is my question. Can i power both the black box and the head unit 93sv on that same 10/2 via a bus bar or am i going to have to run a separate 10/2 cable bow to stern for the head unit as well?

I guess a 3rd option would be to piggy back on the other 10/2 cable i have that will be running the humminbird onix 10 that will be up front.

From an electrician's standpoint, could i even run all 3 on the same main wire/bus bar or does that effect the power that would get to each of the 3 devices?

Thanks

Nevermind. I found enough history on the forum to answer my question. Im going to run the 10/2 to a bussbar up front and then run the unit and ls to the bar on that main 10/2 run.

That will work. I have 2 units tapped off my buss bar that feeds the LS box.
